Nice video 👍🏻 and a 10/10 on the prononciation 🤣 Just finished the edit for a new post “10 tips on How to ride like a Pro”. Your content is really interesting congrats.
Thanks to the Riding School of Greece, trick No2 saved my life in a road trip in Italy, Summer 2019. I was in an open wide turn (over 100km/h) when a bag that I had tied on the back-sit of my bike fell and got stucked between my chain and my wheel. The bike responded like if I suddenly pressed the rear brake but without ABS. It all of a sudden lifted its self and started drawing "snakes" with the rear tyre. The only thing that instantly remembered was my training. "Let the bike stabilize itself and keep your eyes to the point you want to go". And I did. I stayed calm. I focused my eyes in the borderline so that I was less likely hit by a car either from my line or the other line of the road and literally hold the handle bar with just two of my fingers, smoothly. After just a few seconds the bike stabilized itself and I started braking gently. I was safe. In the middle of the borderline but safe. It needs tons of nerve to go against your nature and listen to the voice of the instructors in your head. The instict says "Do something, save the bike, save yourself". The truth is "Let it wobble". Great video as always Mike.

The motocross style leg forward on corners is to move your center of mass forward to get front wheel grip in the corners. You show it once at the end on the dual sport bikes really clearly. It's not quite the same thing as what they are doing on the GP bikes since you corner differently. Your upper body is more upright on an MX bike so the leg really helps get some bite on the front tire.

A few corrections/additions worth including imo 1. Bikes aren't necessarily limited to 1G in braking. The tendency of toppling is based on the angle between the line connecting the contact patch and cg, and ground. That's why despite having harder compound tyres, cruisers stop quicker than supersports. 5. While hanging off with the bike a little less leaned may not improve corner speed in an ideal world, it helps the suspension do its job. Otherwise, when leaned, the chassis must absorb the bumps partially by flexing, and they are lots stiffer than suspensions, the reason of crashes due to smallest of bumps at high lean angles.
Another one: Jorge Lorenzo noticed when he saw the telemetry of Valentino, was that he starts to press the rear brake before cutting the gas, to load the rear suspension and consequently brake harder! Greetings from Argentina, your channel is great!!!
@@KamenKachev During heavy braking the rearbrake isn't used at all !!! They only use the frontbrake and bodypositioning during heavy braking...because the rearwheel lifts off the ground.The rearbrake is absolutely useless when the rearwheel isn't even touching the ground.That's why you see them dangling their leg off the bike when they brake very hard...It provides the riders with more stability going into the corner and it gives them a little bit more surface area that causes drag to slow them down faster.When you learn to ride a motorcycle in order to obtain your motorcycle license...your instructor will tell you that 2/3 of your braking power comes from the frontbrakes and 1/3 from the rearbrake.And that's correct...if you are riding your bike on public roads like a normal person.But in Moto GP...those rules change.A rearwheel that's not even touching the ground doesn't provide any braking power at all.When the rear lifts...all power to decelerate fast comes from the frontbrakes and bodypositioning on the bike.
Motogp riders have a screw loose… they’re like “what if we tried to take high speed turns on a vehicle that is no good at turning and launchs us off if we mess up”
You can only brake at 1g if the center of mass is at a 45 degree angle of the front contact patch, because the braking force is equal to gravity then the total angle of forces equals 45 degrees. Many vehicles can brake at higher than 1g without using wind resistance due to center of mass being lower and further back keeping them below the line of the total direction of force starting from the front contact patch (the angle of the ground and center of mass is less than 45 degrees at the front tire patch). The wobble also has nothing to do with rake, and trail doesn't technically cause it but will amplify it and make it happen easier. Any bike, even with no rake, or reverse rake will wobble when the front wheel comes out of line from the rear wheel's path.
Number 9. Moving their body forwards while accelerating creates a torque to push the front down. But lifting their bottom off the seat shifts where their weight acts on the bike and effectively shifts the bike's CoG. When sitting, the riders weight acts at the seat which is above the bike's CoG, so during acceleration this creates a backwards torque. With their bottom off the seat their weight acts at the foot pegs which is below the bikes CoG creating a forwards torque. This is also why balancing is easier when standing, even just a little bit. The bike's CoG is effectively lower which makes it feel lighter.
0:37 This is assuming that the motorcycle and rider's combined center of gravity is at a 45° angle from the front tyre's contact patch. The higher that angle, the lower braking force is possible before the rear wheel comes off the ground.
It is roughly 45° in a moto gp bike. Trying to reduce the angle from front tire will increase the angle from rear tire, which makes the bike wheelie at very low accelerations. They balanced it where the angle from from and rear are both roughly 45°. One way of decreasing both would be increasing wheel base, which decreases the agility of the bike. Drag racers often stretch their rear axle to allow for much higher accelerations.

Loss of traction is not drifting. Using a vehicle's power to intentionally slide the rear wheel(s) is not drifting. What uneducated people typically call drifting is actually power sliding or just spinning donuts. I've seen idiots call pulling a brodie (e brake slide) drifting. I wish there were so many fucking morons in this world, why do the stupid people have to corrupt and co-opt everything?
@@rivermcratt3683 - you can't comment on the definition of drifting. There isn't really one. Even drifters would not be so toxic as that. Keep drifting fun, they say. Just let the people keep doing what they are doing if they are having fun.
@@Salpeteroxid - we do the same thing in FWD time attack, actually. My Civic time attack car (footage on the Falcon Autosport UA-cam channel) has a reasonable amount of a slip angle on corner entry, let's say about 9° of slip angle. Sometimes, it gets so much oversteer on corner entry, I have to gently correct it, so it will look like this bike thing. It works well in all cars, not just RWD sports cars! 😁
professional? half the gp riders not that smart - they are just gifted in how to ride a bike bloody fast and genetically their balls are bigger than their brains
I found a lot of what you are showing is illustrated in a couple of 30 year old biking books called Twist of the wrist. Beat thing I’ve read that really made me faster and a must for any budding racers
Another ancient book that's never gonna change is "speed and how to obtain it" There's stuff in there from the 30s(maybe earlier) on how to get the most from your powerplant. Here's a link (says our of stock but it shows the cover) www.amazon.com/Speed-How-Obtain-Motor-Cycle/dp/059208082X
Apparently, that's where he's borrowing his insight from, including Keith Code's obsession with reducing the bike's angle (let's see what Marc Marquez has to say on this...)
That book got me on the podium my first race back in 99 at the big Willow track. No engineering degree needed, just a ton of practice up there with the Palomar mtn mafia dragging knee on Sunday mornings 🤘
Finally someone explains speed wobble been looking for years for info on this instead of people saying it happens or just referring to it with no explanation.
Wow, I had no idea the max grip was during slippage. As a person who only Sim races in cars, the idea of gaining speed while basically scrubbing is crazy. Awesome.
I used to stick my leg out when I'd race my friends on my push bike about 15 years ago. Ahead of the curve, me. I used to think it helped me balance and move the bike better. I was right.
Yea haha my buddies are like : what is this MotoGP? I'm climbing all over the darn thing and it's an Enduro but somehow I keep up with the quicker guys in a ride. It corners pretty darned good for what it is but ya gotta throw your weight around to keep it planted. Haha it's like the stadium truck races on asphalt 😂
Same here. I would race my subbings on push bikes and it was ligit intense. And we used alot of the tricks shown in the video. And yeah it just comes naturally.
Every MotoGP bike is a unique prototype that costs a minimum of 1 million and uses the latest technologies for motorcycle innovations. Gyroscopic forces keep it upright! Useful video, but nobody here is Valetino Rossi and shouldn't try certain things either!
As a former road racer it took me actually thinking about it to realize at corner entry I was turning the bars left to enter a right turn(and vice versa for left turns) It all came natural as I slid my butt over to the right that I was doing this but as I thought about the physics it started to make sense. One of the more amazing things I learned when racing I never knew I was doing.
NR7: Short shifting is a driving technique in which the gear is changed up before reaching maximum engine rpm. For example if you accelerate a streetbike in the first gear until the rpm limit, you would land on your back. As soon as the front starts to rise you short shift in the 2nd gear. This will reduce the power and holds the front down.
Another part for #9 - If you watch pro riders come out of a corner, many times you will see them finish the corner then directly go to the other side of the track, basically extending the turn; this is to keep the bike on the smaller part of the wheel longer while accelerating so they can apply more power while keeping the front on the ground.
The only question I have im a kid,I'm 10 years old and I wanna be a Moto GP rider but my question is how do the riders make the bike go back up again when exiting the corner? For me it looks hard or its like the rider is using there on strength to move the bike back to its position if yes I'll lose hope to becoming one.
Hi man, there’s also traction control that helps not going on wheelie while maintaining maximum acceleration that enables you to push beyond that one G, like the computers lower the power to a level that we can’t feel so that we get max accel and traction force. It calculates the spinning speed of both wheels like multiple times every ms. Same with stoppies, there’s like an inertial command unit that controls the force of braking so you can get the max force braking output without flipping over the bike. Also rear braking shifts some weight on the bike. Personally I always initiate emergency braking by gradually applying force on the rear brake then the front. Getting upright is like something we learn when going downhill on a mtb as kids, if not then we have a nice scar on our chin lol. These techniques + the electronic gives like a looooot of gain in performance when combined. Once a gp rider got his traction control cut off by the disks of someone in his tail, exiting the corner he goes full gas : the bike launched itself into a backflip at least 1meter and a half in the air.
The one learned when I first started riding and it saved my life many times was to use the throttle when changing down the gears. Especially when you needed to stop quickly as it stabilised the bike instead of it locking it up and throwing you off. A lot crashes happen because riders just grab the front brake or hit the the rear brake at the same time because they never learned to use the throttle when changing down gears, even at the riding schools that they are supposed to go and learn to ride
@@MickAngelhere good way to train that is to shift without using the clutch (and without quick shifter) put some gas while downshifting and let go of gas while upshifting, there's a sweet spot on every model.
Wobble/tank slappers only cause crashes when riders try to aggressively prevent it. It's almost like a seizure, you can't stop and have to let it go through it's phase.
Yep I have had it happen to me and I just let happen, because the moment you try take control is the moment it throws you off. Scary but exciting at the same time, also the same thing when you go off the track at 150 Kilometres an hour into the dirt and the rear is fishtailing all over the shop . You just gotta let it ride and that’s why I tell people who want to ride a motorbike to learn on the dirt because you get used to the bike moving around and the skills you learn riding in the ditch helps on the road. Look at how Troy Bayliss used to ride in the GPs and in the World Superbikes
#8 is actually done because you want to be positioned where you need to be prior to entering the corner because your movement upsets the bike, and you don't want to be unloading the suspension or upsetting your turn in by sliding over last minute. It doesn't have anything to do with using G forces to move you so you don't use energy lol It's the same idea on corner exit but for the opposite effect - you move back over during a gear change, the shifting already puts a slight pause in acceleration, and if you time your movement with the gear change you can avoid upsetting the bike and having the slightest pause in acceleration on top of the one you get when shifting. Otherwise, good info.

Thankyou Jagadeesh e
Your motorcycle stuff explained series are great!!! I look forward to more of these. They really answer so many questions for me and are so well explained. Thank you!
Could be 1 of 2 things, some MotoGP bikes, if not all have the ability to have the rear brake automatically activate a certain percentage upon application to the front brake. This tech can be found on 2015 and up R1's and other high end super bikes, Ducati BMW Aprilia etc... Having that technology on their bikes is a preference so explanation #2 could be some racers would rather just use the front brake and engine braking to slow the bike, thus transferring weight to the front tire, de-weighting the rear tire forcing a controlled slide. Hope this helps!
@@009Daft600 I couldn't find much on this online😅 that's why asked. Could you give more information. Like which side of the handlebar is it located & can it modulate the braking ?
I think you went through the Trail braking too quick, its one of the most important skill right now which helps riders could brake later and accelerate more quickly
Curve Ahead trail braking will help you to brake more later, dont misunderstand with the sliding, when you doing the trail braking basicly the bike will turn more easier and quicker. In the past, lots of riders they braking on the straight, then using the engine to harm the bike during 1/2 or 2/3 of the corner, that takes time. So years later riders’ve change their braking style, thanks for the good front shock, tyres, and electric controllers, they could brake in the corner more smoother and easier, so usually they will brake to the 1/2 or 2/3 of the corner depend on riders and once they finished the braking they will go full throattle to exit the corner or even doing it combine! So insane
Dad (77yo) just got a ktm rc390 last year and I ride his old Yamaha wr250. I've been riding dirt forever , and got my permit last year finally. I was always spooked by the road and idiots on it , but we had a blast last summer. Can't wait to go ripping around this year, and I'm kicking myself saying I should have done this years ago. Quality time with pops , an old flattrack racer from the 60s that I don't have a prayer of keeping up with if he wants to run and hide. He bombs those corners like I've never seen someone do on the street. If I can pick up 10% of his skills I'll be a good rider.
In mountain bike racing we do tend to move or bodies to suit how much we are braking or do something similar with our outside foot while cornering too . Great video
i do a bit of trackriding ( check my vids) and although im not very talented i think almost everything you explained comes natural for any rider as he moves up slowly in pace
I love your content very much explaining how motogp riders do what they do. I've been following and watching all your videos from Tyre traction to motorcycle geometry. Am a motorcycle addict with no motorcycle
I see road riders all the time with their feet asking to get ripped off and i can't figure out why...The bikes are great but the riders are a different story. These bikes scare me so powerful I owned a 2010 R1 and it was so fast I got rid of it as I didnt have a track to ride to its potential or I was just a big pussy one of the 2. Ride safe lads
Loved the video mate but the LEG DANGLE was used AND ABUSED LOL on my HONDA MTX 200 IN THE WOODS IN THE 80`S and I sure as hell won`t be using it on my HONDA VTR 1000 ON THE ROAD :) LOVED THE VIDEO MATE !!:)
I miss the joy of tesring up the canyons in SoCal. Going thru the gearbox, hearing the motor rev, hard braking, lean angles, quick roll ons out if the corners and while front wheel is slight off the ground thru 2nd and 3rd gear, going into 4th, just to click 3 down and do it again, while diving into the next corner.
I used to say this to my ex wife. In the helmet you are truly alone. No kids, no nagging, no phone, no radio. Just you and your thoughts and if you're really pushing those thoughts go and you have a moment of peace
I learned all this from trial and error, well most of it since I raced motocross not on asphalt so things like the knee and leaning are different on dirt but the death wobble happens on straights on dirtbikes as well and if you fight it or try to break and slow down your screwed. Best bet in a wobble is to accelerate and you'll pull out of it.
Quality content. Technically accurate, spot on with the physics...and explained beautifully. Reminds me of things I know plus new insight and questions. 👍🙏 Liked and subbed. Looking forward to more.
Whoa. So when I’m at 45mph leaning deep in a corner, I’m actually only at 40mph. I knew this, but didn’t realize it - if that makes sense. Great video! Thanks. I’m gonna go think about these when I ride :)
Never watched MotoGP, but as I miss my bike (broke down), this just caught me and I wanted to see it. And now when I get my bike running again... well, I need to find a track (and a better bike).
This video is very interesting for some one like me, who knows nothing about how bikes perform. I enjoyed watching it and in fact watched it a few times. Thank you 🙂 Well done!!!

@@Salpeteroxid - we do the same thing in FWD time attack, actually. My Civic time attack car (footage on the Falcon Autosport UA-cam channel) has a reasonable amount of a slip angle on corner entry, let's say about 9° of slip angle. Sometimes, it gets so much oversteer on corner entry, I have to gently correct it, so it will look like this bike thing. It works well in all cars, not just RWD sports cars! 😁
The reason I keep coming back to this channel is the way you explain it with the physics involved which makes it so simple to understand
More proof that professional athletes are actually pretty damn smart... Very well done video!
professional? half the gp riders not that smart - they are just gifted in how to ride a bike bloody fast and genetically their balls are bigger than their brains
They're clever on what they do, but doesn't mean they're clever on anything else. Just like many football or basketball players.
I found a lot of what you are showing is illustrated in a couple of 30 year old biking books called Twist of the wrist.
Beat thing I’ve read that really made me faster and a must for any budding racers
Another ancient book that's never gonna change is "speed and how to obtain it"
There's stuff in there from the 30s(maybe earlier) on how to get the most from your powerplant.
Here's a link
(says our of stock but it shows the cover)
www.amazon.com/Speed-How-Obtain-Motor-Cycle/dp/059208082X
Apparently, that's where he's borrowing his insight from, including Keith Code's obsession with reducing the bike's angle (let's see what Marc Marquez has to say on this...)
That book got me on the podium my first race back in 99 at the big Willow track. No engineering degree needed, just a ton of practice up there with the Palomar mtn mafia dragging knee on Sunday mornings 🤘
Finally someone explains speed wobble been looking for years for info on this instead of people saying it happens or just referring to it with no explanation.
Do you know what a high side is? Fighting those at high speed in track conditions. Don't tell me you have had this happen, ha.
Wow, I had no idea the max grip was during slippage. As a person who only Sim races in cars, the idea of gaining speed while basically scrubbing is crazy. Awesome.
2:13 watch that in 0.5 speed
the way his head jerks when it hits the ground is terrifying
I used to stick my leg out when I'd race my friends on my push bike about 15 years ago. Ahead of the curve, me. I used to think it helped me balance and move the bike better. I was right.
It's just instinct, I do it too on my sportbike if I'm cornering hard
Yea haha my buddies are like : what is this MotoGP?
I'm climbing all over the darn thing and it's an Enduro but somehow I keep up with the quicker guys in a ride.
It corners pretty darned good for what it is but ya gotta throw your weight around to keep it planted.
Haha it's like the stadium truck races on asphalt 😂
I bet you weren't thinking about physics when you were doing it.
Pseudo effect. It does nothing. They do it because it feels better. Rossi did a couple laps doing the dangle and no dangle. They were negligible.
Same here. I would race my subbings on push bikes and it was ligit intense. And we used alot of the tricks shown in the video. And yeah it just comes naturally.
The violin goes so well with the intro.
These slow motion shots have my mind blow it’s so beautiful!
Every MotoGP bike is a unique prototype that costs a minimum of 1 million and uses the latest technologies for motorcycle innovations. Gyroscopic forces keep it upright! Useful video, but nobody here is Valetino Rossi and shouldn't try certain things either!
Thanks for all your time, i am an amateur racer and love techincal explination, you do it good, good voice, no clutter, great clips. Have a good day.
As a former road racer it took me actually thinking about it to realize at corner entry I was turning the bars left to enter a right turn(and vice versa for left turns) It all came natural as I slid my butt over to the right that I was doing this but as I thought about the physics it started to make sense. One of the more amazing things I learned when racing I never knew I was doing.
That's a really great explanation and right to the point. The clips you have chosen are really good as well. Waiting for the MotoGP season. Cheers :)
Thanks!
NR7: Short shifting is a driving technique in which the gear is changed up before reaching maximum engine rpm. For example if you accelerate a streetbike in the first gear until the rpm limit, you would land on your back. As soon as the front starts to rise you short shift in the 2nd gear. This will reduce the power and holds the front down.
I like the other tips. Sliding forward at the end of the brake manover simplifies so much.
Another part for #9 - If you watch pro riders come out of a corner, many times you will see them finish the corner then directly go to the other side of the track, basically extending the turn; this is to keep the bike on the smaller part of the wheel longer while accelerating so they can apply more power while keeping the front on the ground.
The only question I have im a kid,I'm 10 years old and I wanna be a Moto GP rider but my question is how do the riders make the bike go back up again when exiting the corner? For me it looks hard or its like the rider is using there on strength to move the bike back to its position if yes I'll lose hope to becoming one.
So basically I've accidentally been acting like a MotoGP rider by sitting up straight when I'm going to be braking hard
Yep, but if you're not doing the leg dangle, you don't qualify.
I didnt even watch motoGP but i love your explaination
Interesting to listen and watch. Keep up the good work 💪 thank you, Mike!
Thanks!
Hi man, there’s also traction control that helps not going on wheelie while maintaining maximum acceleration that enables you to push beyond that one G, like the computers lower the power to a level that we can’t feel so that we get max accel and traction force. It calculates the spinning speed of both wheels like multiple times every ms.
Same with stoppies, there’s like an inertial command unit that controls the force of braking so you can get the max force braking output without flipping over the bike. Also rear braking shifts some weight on the bike. Personally I always initiate emergency braking by gradually applying force on the rear brake then the front. Getting upright is like something we learn when going downhill on a mtb as kids, if not then we have a nice scar on our chin lol.
These techniques + the electronic gives like a looooot of gain in performance when combined.
Once a gp rider got his traction control cut off by the disks of someone in his tail, exiting the corner he goes full gas : the bike launched itself into a backflip at least 1meter and a half in the air.
The one learned when I first started riding and it saved my life many times was to use the throttle when changing down the gears. Especially when you needed to stop quickly as it stabilised the bike instead of it locking it up and throwing you off.
A lot crashes happen because riders just grab the front brake or hit the the rear brake at the same time because they never learned to use the throttle when changing down gears, even at the riding schools that they are supposed to go and learn to ride
@@MickAngelhere good way to train that is to shift without using the clutch (and without quick shifter) put some gas while downshifting and let go of gas while upshifting, there's a sweet spot on every model.
Finally my questions are answered!! Phew! Thanks for the clear explanations.
Thank you for all the slow mo these are beautifully shot
I did not know that leaving the bike Wobbling was a good idea.
Thank you for your work !
Wobble/tank slappers only cause crashes when riders try to aggressively prevent it. It's almost like a seizure, you can't stop and have to let it go through it's phase.
If you're really confident? the best way out of a 'Tankslapper' is a small wheelie and briefly get that front wheel of the floor.
Yep I have had it happen to me and I just let happen, because the moment you try take control is the moment it throws you off.
Scary but exciting at the same time, also the same thing when you go off the track at 150 Kilometres an hour into the dirt and the rear is fishtailing all over the shop . You just gotta let it ride and that’s why I tell people who want to ride a motorbike to learn on the dirt because you get used to the bike moving around and the skills you learn riding in the ditch helps on the road.
Look at how Troy Bayliss used to ride in the GPs and in the World Superbikes
#8 is actually done because you want to be positioned where you need to be prior to entering the corner because your movement upsets the bike, and you don't want to be unloading the suspension or upsetting your turn in by sliding over last minute. It doesn't have anything to do with using G forces to move you so you don't use energy lol It's the same idea on corner exit but for the opposite effect - you move back over during a gear change, the shifting already puts a slight pause in acceleration, and if you time your movement with the gear change you can avoid upsetting the bike and having the slightest pause in acceleration on top of the one you get when shifting. Otherwise, good info.
Hey Mike, love your content! Did you go to school for engineering? Your explanations are so good!
He did he went to google

Excellent video quality. Perhaps the best on UA-cam. Cheers, Kirb.
again excellent content ...good work Mike..makes one really appreciate the skill top riders have worked on through practice and commitment.. like all masters of one's craft whatever it is..thank you and stay healthy & well during these,challenging times ...having your videos to watch while being house bound more or less is far better than watching the news and the doom & gloom they present day in and day out...I am going to get out for a ride today...a little medicine for the soul.. have a good day

1:25 - A long time ago, I had an EX500 that would get a wobble on a certain section of highway due to the pavement. It used to freak me out. A guy I worked with said what you did - grip the tank with your knees, relax on the handlebars - and I couldn't believe how well it worked.
“but what are they actually doing, and why?” “here are 10 things...... to go faster” you already gave the answer
Extraordinary details you gave to practice in so many ways...thankyou...

Missed an opportunity to show off Dani Pedrosa's incredible stoppie at Motegi (?).
Wow, the whole leg dangle thing I've done that for years on bicycles, gives me more control
1st vid I‘ve watched learned more than in driving school cheers from Germany
awesome video. i must admit, your the only person ive ever heard pronouncing the p in pneumatic LOL
Your motorcycle stuff explained series are great!!! I look forward to more of these. They really answer so many questions for me and are so well explained. Thank you!
How do MotoGP Riders use their Rear Brakes when they are sliding into a Right corner, doing something like the Doctor's Dangle?
Amateur PetrolHead they dont use the rear brakes. they would imedeatly slide.
They have a button on the handlebar that controls the rear brake
Could be 1 of 2 things, some MotoGP bikes, if not all have the ability to have the rear brake automatically activate a certain percentage upon application to the front brake. This tech can be found on 2015 and up R1's and other high end super bikes, Ducati BMW Aprilia etc... Having that technology on their bikes is a preference so explanation #2 could be some racers would rather just use the front brake and engine braking to slow the bike, thus transferring weight to the front tire, de-weighting the rear tire forcing a controlled slide.
Hope this helps!
@@SebF423 oh, okay
@@009Daft600 I couldn't find much on this online😅 that's why asked.
Could you give more information. Like which side of the handlebar is it located & can it modulate the braking ?
Bro is a legend for using Valentino Rossi's Bank in the video, i noticed it cause on his back was "The doctor"
I think you went through the Trail braking too quick, its one of the most important skill right now which helps riders could brake later and accelerate more quickly
How do you relate trail braking to acceleration? That's two different phases in cornering, entering and exiting.
Curve Ahead trail braking will help you to brake more later, dont misunderstand with the sliding, when you doing the trail braking basicly the bike will turn more easier and quicker. In the past, lots of riders they braking on the straight, then using the engine to harm the bike during 1/2 or 2/3 of the corner, that takes time. So years later riders’ve change their braking style, thanks for the good front shock, tyres, and electric controllers, they could brake in the corner more smoother and easier, so usually they will brake to the 1/2 or 2/3 of the corner depend on riders and once they finished the braking they will go full throattle to exit the corner or even doing it combine! So insane
I wanna apologize for exploring your channel just now. Thank you so much for making this video.
I learned a few tips thru my grandad as hes done this sort of stuff decades ago rip grandad 🙏👍
Dad (77yo) just got a ktm rc390 last year and I ride his old Yamaha wr250.
I've been riding dirt forever , and got my permit last year finally.
I was always spooked by the road and idiots on it , but we had a blast last summer.
Can't wait to go ripping around this year, and I'm kicking myself saying I should have done this years ago.
Quality time with pops , an old flattrack racer from the 60s that I don't have a prayer of keeping up with if he wants to run and hide.
He bombs those corners like I've never seen someone do on the street.
If I can pick up 10% of his skills I'll be a good rider.
Dang he lost the gulag
In mountain bike racing we do tend to move or bodies to suit how much we are braking or do something similar with our outside foot while cornering too . Great video
i do a bit of trackriding ( check my vids) and although im not very talented i think almost everything you explained comes natural for any rider as he moves up slowly in pace
I love your content very much explaining how motogp riders do what they do. I've been following and watching all your videos from Tyre traction to motorcycle geometry. Am a motorcycle addict with no motorcycle
THANK YOU BRO NOW I CAN GET BACK TO MY GAME THIS HELPS ME IUT ALOT 😂
This is the only channel I hit the get notification button!
Are you Swedish? You've got some clear accent.
I’m not a bike rider but love the technical features and science here. Similar as I like F1 car science. Thank you boss!
Just a wild guess: the narrator/person behind this is from sweden? Just something with the accent :) Helsning fra Norge!
Perkele
First word I was like aaah yeah a swedish dude. Hälsningar från en svensk jävel.
Me too... heard an familiar tune in there :)
I really love the slow motion footage in this video
I see road riders all the time with their feet asking to get ripped off and i can't figure out why...The bikes are great but the riders are a different story.
These bikes scare me so powerful I owned a 2010 R1 and it was so fast I got rid of it as I didnt have a track to ride to its potential or I was just a big pussy one of the 2. Ride safe lads
Feet won't get ripped off, you'll just put a hole in your shoes.
Loved the video mate but the LEG DANGLE was used AND ABUSED LOL on my HONDA MTX 200 IN THE WOODS IN THE 80`S and I sure as hell won`t be using it on my HONDA VTR 1000 ON THE ROAD :)
LOVED THE VIDEO MATE !!:)
ROSSI tryied to help push marquez down but then they all complained about it.
I have no clue why this video popped up on my UA-cam feed, but I am glad it did. Pretty cool information.
2:58.. one problem, I don’t have a bike 😂
I knew pro guys like this were obviously very skilled but this just took it to a level I never would have thought existed. Insane...
I've never heard someone pronounce "Pneumatic" like Peh-Neumatic before.
I miss the joy of tesring up the canyons in SoCal.
Going thru the gearbox, hearing the motor rev, hard braking, lean angles, quick roll ons out if the corners and while front wheel is slight off the ground thru 2nd and 3rd gear, going into 4th, just to click 3 down and do it again, while diving into the next corner.
Life on 2 wheels is unexplainable it's jus a beautiful fealing u an a machine against the world 🤫🤫🤫
I used to say this to my ex wife. In the helmet you are truly alone. No kids, no nagging, no phone, no radio. Just you and your thoughts and if you're really pushing those thoughts go and you have a moment of peace
I learned all this from trial and error, well most of it since I raced motocross not on asphalt so things like the knee and leaning are different on dirt but the death wobble happens on straights on dirtbikes as well and if you fight it or try to break and slow down your screwed. Best bet in a wobble is to accelerate and you'll pull out of it.
Ohk .. now sign me for MotoGP race .. I know how to race
Rossi started all those methods. Brilliant video.I went to knock hill and adapted this vid to my riding. Brandshatch was awesome also.
You Swedish right? I recognize the accent ;)
Quality content. Technically accurate, spot on with the physics...and explained beautifully.
Reminds me of things I know plus new insight and questions.
👍🙏
Liked and subbed. Looking forward to more.
2:58 What makes you think I have a bike?
... or a garage.
TheFunnyBuddy or money
Whoa. So when I’m at 45mph leaning deep in a corner, I’m actually only at 40mph. I knew this, but didn’t realize it - if that makes sense.
Great video! Thanks. I’m gonna go think about these when I ride :)
4:22 *INCCCREASE*
Never watched MotoGP, but as I miss my bike (broke down), this just caught me and I wanted to see it. And now when I get my bike running again... well, I need to find a track (and a better bike).
3:44🔥🔥🔥
the visual did magic for me now im into MotoGP heavy the drivers are amazing especially Marquez
#9 Well what you achieve by standing up when accelerating is that you move your center of gravity forward to counteract the wheelie.
If you want to know how to go fast on a bike, watch road racing, specifically the Ulster Grand Prix.
The most amazing fact was about the RPM at turns. I had no idea of it. Thanx man
No one:
This guy: Have you ever seen the riders cellular respiration?
This video is very interesting for some one like me, who knows nothing about how bikes perform. I enjoyed watching it and in fact watched it a few times. Thank you 🙂 Well done!!!
