- How can a simple math equation help us make the corner, every time, on any bike.
There are very few things more important on a motorcycle than taking the right line in a corner. We’ll cover just how critical the relationship is between your speed and how radius is affected by the role brakes, throttle, and lean angle are in this vital equation.

Here because Fast Eddie from MotoJitsu thought it would teach me something. He was right.
Same!
Same, and I bought the online course and have exactly zero regrets.
@@groundsurvivalstudygracieg4034 they have online courses?
For anyone that’s just starting out their riding career. I highly recommend to watch all of these champ talk videos. And really understand what your watching and listening to. It will make u such a more confident and faster rider all while being a safer rider as well! These really are the core principles of riding!
Thanks!
I'm so glad Motojitsu sent me here. Thank you!
Thanks!
Ditto
Took your class years ago. This one technique alone was so useful, it saved my bacon numerous times. Now it becomes 2nd nature. Thank you!
Curtis To glad to hear your bacon is well and good. Please subscribe and share.
I am so pissed right now. I instinctively knew this to be the case and had everyone and their mom telling me I was wrong and you aren't supposed to brake when cornering etc. etc. Glad I have a video to shove in the face of anyone that tries to argue this with me. It's scary how many people are in positions of authority on motorcycle coaching that clearly don't know shit. Thanks for this vid, guys.
Accurate statement. We several more videos on trail braking here and on our FB page. Please enjoy using them in as many arguments you like.
@@Ridelikeachampionycrs will do.
U can brake while cornering, however u don't need to.
@@Adrenalean767 you shut your mouth slim
RiderCoach here for MSF. I will say at the basic beginner rider level it is taught to NOT brake mid turn at all because you are being trained the very fundamental skills of riding a motorcycle. If we add lean angle and trail braking into the mix it overcomplicates and offers a lot more risk for the student to over brake and wreck during the class. The basic rider course is not designed to be the end all be all of your motorcycle education. It is only the fundamental basics to get you riding.
This is priceless. I'm certain that drilling this lesson into my memory will save my life one day. Thanks for posting the lesson!
Never touch your brakes when going through the New Orleans Housing Projects regardless of lean angle...
This is possibly even more important than the title suggests, since the real physics equation is R ∝ MPH^2...!
Yeah, this warrants a lot of attention for that very small amount of brake pressure has a squared impact on radius and the ability to control our turn.
Outstanding video!! I think more of these kinds of videos are what most riders need. Simple equations, soundbites, and the like that riders can remember while riding at speed. The 100 points of grip was another video that really made me think about being smooth on throttle and brakes. "Load it before you use it"......simple, memorable, and most of all usable. Please continue to make more of these videos!
Keith Whiting thank Keith. Check our www.champschool.com sign up for newsletter. Tons of articles on the blog and lots more video on Facebook.
Outstanding. Sport rider 30+ years, I've been doing some of this instinctively, but having it explained and laid out, is tremendous.
I do this; trail brake until I’m happy with speed and direction. But I end up being too slow. I want to go a little faster in the corners, but I’m not trusting my tires. I don’t know how much the tires can take before they slip. I’ve watched the 100 points of grip.
It could also be that I’m just too cautious. I’m a risk manager and always err on the side of safety.
If you can find a track day near you, it's worthwhile. Some have coaches to help.
The best tutorials ever!
That teaching style is excellent. Great advice and great delivery of that advice.
The topic discussed here is critical for safety. it's insane that Slow look press and roll is still taught as a mainstream technique.
such eye opening material.
really good stuff
Awesome...! This video is Lifelong...! Great Video and Easily explained...! Thank You and Do continue making these videos...!
Great content.......life saving tips
Thanks for articulating what we have been learning through skids and scrapes. ;)
I wish I would have seen this video first. Brilliant!
Please do make more videos about more techniques......great video👏👏👏
Dammmmmmm!!!!!! You guys are the bombbbbb on bikes.
Legend and legendary tutorials. God bless. Glad to incorporate them into my street riding and I can already see me unlearning..
Really informative video. 👍
This is so good its amazing. He puts action to the words in a real world training situation! I have been doing this for a long time eg using some braking until a I feel comfortable with the speed and radius in the corner but almost felt bad about it because I was taught to brake first then steer into the curve.
Trail braking is such a HUGE essential asset to street riding. MSF literally didn't teach this in their course.
Or rev matching
MSF is basic training and info for new riders. You don't teach trail braking to someone that doesn't know how to countersteer for example.
@@tripwarrobots8157 what is rev matching?

Thank you very much for the GREAT video. You are doing great work for a of of riders.
Thank you!
This is perfect teaching.
You’r videos will probably save thousands of lives. I live in Norway, but when the pandemic is over, i will come over seas to take your classes in real life. Thank you so much on behalf off all the riders that learn from you. In Norway, the number one accident reason for bikers are cornering failure. This video, and 100 points of grip will prevent me and mines to becoming a part of that statistic. Thank you so much!
Thank you!
thank you !
that is simply brilliant, so well explained, thank you
Instant subscriber thanks guys for the solid info.
Thank you!
It's a shame that this isn't being taught as a basic skill everywhere in the world. The only thing I see on the road is people changing lean angle several times through tightening turns or with obstacles in them, making what could have been a nice even turn with a steady lean angle into a nightmare of a show. I don't have yet my license but I'm trying to get these concepts carved into my brain for when I get it. Thanks for sharing these, specially for people that don't have access to any of these advanced riding courses nearby.
True story....
Loved this video, thank you.
You're very welcome!
So cool with the jets in the background
I can guarantee you one thing. Mark is happy with his speed and direction
Something I noticed intuitively: lean angle depends on speed. You can't put too much lean angle without enough speed to back it up either. The faster the speed the deeper the lean and vice virsa.
Pure gold!
Wow, Thanks to Champion Nick Ianesch for the lesson. The statement has a great goal for asphalt riding on or off track riding. Radius =MPH!!
Best of best video on youtube
Great Video
This video should go millions of views.....
This video is pure motorcycle riding science.
What a great video. Motojitsu sent me here

Thank you for this video! What I still don't understand is: why can I not increase lean-angle, while increasing brake (applied smoothly)?
AWESOME AWESOME AWESOME CHANNEL, AWESOME VIDEO!
Good advice from actual pro's who know their stuff, as opposed to keyboard warriors!

@@Ridelikeachampionycrs I just have sent an email.
Awesome vid!
Thanks!
Its exactly like a car. Speed equals radius. I don't care what kind of car it is, you can only go so fast through a given turn. You go too fast you will not make it through the turn. You push too hard coming out you won't make it out. I knew this from driving sports cars and following motorsports all my life. But its nice seeing this video confirm what I knew to be true.
29 years riding bikes and this is the first time I've heard this being taught. Fantastic. This is something I just did naturally, but never really spoke about it as we were always taught to brake in a straight line - that didn't work for me though. I've always found myself trailing my brakes into corners. Have some Kudos from the UK.
Awesome!
With all do respect, I take issue with the expression (Radius=MPH), because it suggests a 1 to 1 , or linear relationship, which it is not. I think a more accurate expression is (Speed Squared = Radius) For example: At any lean angle, 10% reduction in speed shrinks your turn radius by 19%. Also, Speed Squared = stopping distance, and crash impact force.Thank you so much for all your videos
Great points.
A follow up video to include this might be great; including stopping distance, reaction time, etc. This video could be remade to shorten the time. The animated diagrams and many examples are gold.
Gentlemen,
Reddit sent me here and I'm Blessed that they did. I have a 21'MT-07 with only 33 miles on it. I'm a brand new rider at 59. I know you probably get asked this question a lot, could you please recommend a tire(s) that will perform in weather and/or road conditions? again thank you for this video.
...Ride Safe Everyone..
So if im in a decreasing radius corner i roll off the throttle smoothly and slowly and do i increase lean angle or does it stay the same?
This video should have a lot more views!! My intuition is confirmed by the experts. No such thing as fast line through a corner. The rider had skills, not the fast line. R=MPH plan and simple!!
Well, there *is* a fast line through the corner, but to ride that fast line you have to trail your brakes into the turn and roll onto the throttle out of it, like they described in the video. A line alone won't make anyone fast.
Great vid! Do you completely roll off the throttle when you are on the brakes or are you using maintenance throttle?? Thanks
We always close the throttle completely while on the brakes. Always.
Ride Like A Champion Thank you very much!! The only way to ride!! Keep the vids coming.
The only time to use the throttle is to blip for downshift rev matching to keep from locking the rear tire.
This is so understandable even for me a Spanish speaker..! Thanks... Hope you get more subscribers! @CMartinSalomon I am sharing this with my friends!
Thank you!
Thank you! R= MPH; Done!
Thank you!

cornering on a dirtbike just seems like a different animal. On a street road or track, your body weight goes inside so you don't have to lean the bike as much. On the dirt, your body weight goes on the outside foot peg, so you have to lean the bike more but you're putting weight on those inside knobbies for traction. And also you have a rut or berm to help with traction through the corner. Enjoying the Champ U courses and putting the info into practice on my KTM Duke.
It is all related to the amount of available of traction and duration at lean angle. If you rode a street bike on gravel, you would ride like a dirt bike.
Yep, get on it on a dirt road or a wash in the desert. Street bike will do the same as a dirt bike.
The big difference happened in the 1980's. The Honda CB's, Kawasaki kz's etc. Had lots of trail & not a steep rake. You could kick out the backend like a dirt bike on the asphalt. They were also tank slappers! Get the front end light, they followed road imperfections. Ya get comfortable with it eventually.
When all the newer sport bikes with 16 or 17 inch tires with a steeper rake & less trail came out. Had to be careful not to kick out the rear like the older bikes. Or you will high side.
As much as I like the better handling of the newer bikes. I miss being able to kick out the rear like you could on he 60's, 70's, early 80's bikes with no fear of high siding.
Having started riding dirt bikes. My opinion is that everyone should learn in the dirt before getting on the street. As well as truly understand how your motorcycle was designed to handle.
There are simply body movements & memory mussle that gets built riding in the dirt that will help you out on the street. You simply cannot be sliding around doing what you can do in the dirt. Wreck get up & try it again.
You will get seriously injured or killed doing that stuff on the street, or arrested. Having done all the sliding around in the dirt. Provides you with memory mussle that will save you in some circumstances on the street.
Usually some asswipe in a car or pickup that forces you to slide around to keep from hitting them or going down.
Excellent information!
ah, now I get it, DUGH ! , slowing down is the key to making it alive ( in this case to avoid running wide), brakes are not just for stopping, its good for slowing down :D
and *turning.*
sometimes if i break sooner than i`m loosing 2 much speed and than i got no speed at all before i`m going into the corner. my question is if it is possible to break sooner and have a littlebit steady trottle wile breaking and take the steady trottle into the corner with the breaks on? or am i doing something wrong?
greetings from holland.
Hallo etienne Schaarman! Think about using your brakes at a lighter pressure for a longer time into the corner. If you over slow the entry, you can use a neutral throttle if you are happy with your speed and direction of the motorcycle. You don't want to overlap throttle and brakes as you are giving the bike 2 different signals.
@@Ridelikeachampionycrs thanks for the answer
Two GREAT guys with an unlimited amount of GREAT information. Check out their school...you wont regret it.....regardless of your skill level.
I’m in Texas how can we get these classes? I’m assuming that champ school is in California, can someone confirm where the school is?
Special thanks to Fast Eddie over at Motojitsu for referring me here... AND thanks you guys for clearing up visually and SIMPLY what the techniques really entail...
Now... It's time (for me) to "Shut up and practice"... ;o)
When you say use the breaks to you mean only frount break or we Can use both frount and back break, going down hill by example? Thank you.
Yes, you can use both brakes. The limit is that as you apply brakes weight is transferred forward away from the rear tire, limiting the rear brakes effectiveness.
@@Ridelikeachampionycrs 🙏
👍👍👍👍👍👍👍👍👍👍👍👍👍👍
uhm .... any advice for people riding with Honda's Linked Brake System (like me? - ST1100 ABSII)
Same technique. A slowing motorcycle decreases its radius, a accelerating motorcycle increases its radius.
Is twist of the wrist outdated advice? Because this advice contradicts what that film says.
i was on a mountain road here in europe last summer and i went downhill and i thought okay i use my breake into the corner and i was struggling to keep traction and to keep the bike on the road and the bike felt heavy on the front . i was lucky and i did`nt fall... did i went too fast in the corner and because of that used to much breaks or did i break to long in to the corner?
greetings from holland
Neither... the reality is that when riding downhill, you're inevitably going to be feeling like you're putting more weight into the front of the motorcycle through the handle bars as you're angled forwards. However, you'll actually need *more* brakes (as said in the video) for the front *tire* to see the same amount of load from the motorcycle. So either you were doing it properly and just weren't used to the sensation of loading more weight into the handlebars, or you were actually using too little brakes and the front was still under loaded
Try braking earlier and LIGHTER pressure for smoother slowing (no sudden forward weight transfer) and keep braking longer and that feeling of over braking and struggling to maintain traction will go away
Rumor has it that Champschool runs a special "kipper for breakfast" day once a year with high protein low ash/carbon hand picked pairs (whole) air freighted in once the season kicks in.....direct from the Devereau's of Peel race department. Pre knife and fork handling /training classes maybe required/necessary for the none front brake (sickle) stick ( car) types ...
I love R=Mph,100 points of grip, butt and brakes...and Sport Riding techniques...thank you for this body of work....a small request... a vid on "the eyes have it"....this particular chapter really gave me much needed info on this part of riding....and just like R=Mph in the book it was great to see in a video...
A small question....in an ascending corner say up a hill....which requires a lil more than maintenance throttle....how do you manage uphill corners prior to seeing to seeing the exit in order to take away lean points?
Thank you
i think is better to keep neutral and slowdown to anticipate everything when up a hill,
To be clear, there is no single maintenance throttle level. Maintenance throttle is whatever level of throttle keeps your bike travelling at a constant speed, no matter the situation you're in. If you're going uphill, the actual throttle level you'll hold for "maintenance throttle" will be higher than going flat or downhill. In fact, maintenance throttle going downhill steep enough might actually be "maintenance brakes"
When you tell some of the things to dutch instructors that champschool teaches like trailbraking on the public road or even letting your leg dangle in slow corners, some of them are just dumbfounded and respond with " Americans are crazy" but then again they don't even teach conscience counter steering, you just lean into the corner these guys teach, well they do teach that if you need to do an evasive maneuver then you push left to go left and push right to go right. Champschool teaching is on a whole different level
Thank you!
Ok 👍🇵🇰♥️
Question that has been confusing me....so assuming a long, constant radius sweeping corner, and the bike is settled, and the throttle is constant (some maintenance throttle keeping the bike at speed), this would be the only theoretical safe place to add lean angle points, assuming all aspects stated above are constant, correct? Because there are no acceleration points, or braking points being used in this situation?
Correct. Neutral throttle is no adding acceleration.
@@Ridelikeachampionycrs thanks!! See you in May at njmp for champ day!!
MikSane can’t wait to have you!!
Woot!
Nope, it's wrong, radius equals speed squared 😅
Maintaining same apetite for the traction pizza means twice the speed requires four times the radius. And the opposite looks nicer - twice speed drop can guarantee a four times tighter corner for you.
Trail braking gave me confidence I lacked! Thanks!
Gi Yoon it’s the best knowing anywhere, anytime, any place you got your brakes.
this are literally motorcycle riding and physics basics lol
Is there a champschool in belgium?
Not at this time....
How do you prevent people behind you from freaking out while trail braking in a corner? I’d hate to cause a wreck because someone behind me doesn’t realize what pressure I’m putting on my front brake? They see red and panic.
you take that corner hella smooth so they can be conditioned to not panic
Spread the word to your friends. If someone is liable to panic and crash just from seeing a brake light in front of them in a turn... you probably don't want to be riding with that person in the first place until they correct their skills, honestly!
They should not be that close behind you. That is just not smart for them to be so close behind you in a corner that they can't deal with anything you may do.
I panic more following riders who solely use their engine braking to slow down, thus never illuminating their rear light. As a lead rider I always try to just tap the front brake even if Im only slightly decelerating from engine braking to let those behind me know. More info is better.
how come twist of the wrist says u can somehow tighten up the turn by adding throttle and keeping the rear suspension expanded?
Keith from YCRS here. I've heard that before from other, less reliable sources and believe it is 100% incorrect as a stand-alone statement but knowing Keith (the original Keith) ain't no fool, I would need to see that to get the full context of the situation he is describing. I have the book so if you know what page, I would be happy to find and try to answer your question. If you can't find it or you are still not sure, go find a large empty parking lot and try both techniques and let us know what works. We're pretty confident we know the answer.
But when u add throttle the bike wants to standup not tighten. I'm not sure how adding throttle would tighten the line.
You CAN however do that in a car with a limited slip differential, because the diff will change the torque distribution between the inner and outside tire and allow u to steer with the throttle. (Works in all cars with LSD especially in RWD).
Dont do that with non LSD cars as they will behave like motorcycles and understeer...
R=mph is a good way to think about it and will help you be more consistent in most vehicles. Cars with LSD CAN "BEND" this rule to a point... Once u exceed the traction limit or 100 points of grip its game over in any vehicle...
Bikes like the Ducati pannigale V4R CAN do what you describe but its because its traction control and yaw sensors are figuring things out for you and letting you do whats technically not possible...
That said its better to learn good technique then use the bike to bend the rules than to have bad technique and rely on the bike to save you, or cover up your mistakes....
@@3star2nr "Technique over Technology" - well said.
Interesting about the Ducati but speak to MotoAmerica Ducati Superbike racer Kyle Wyman about that before you try it on a V4R. Ain't nobody (in America) going faster than him on a Panigale and he never adds throttle to tighten his radius.
@@tommarrone5378 agreed everything u said is fact. And yes you always want to think of tires as only able to do one thing well at a time. If u ask them to slow down, change direction, maintain grip and accelerate they are going to get "confused" I.e. give up grip.
You have to constantly and smoothly transition between all 3 things
Mark at 01:58 .. Weeeeee 😂
Great information. I have a question regarding adding lean angle or taking out lean angle. I was taught that the only two inputs on a motorcycle are speed (throttle and braking) and direction (steering inputs), and lean angle is the RESULT of speed and direction inputs. Why would you want to directly control lean angle, you are trying to go a certain direction at a certain speed. Nobody says I want to take this corner at X degrees of lean angle. Appreciate all your videos.
You are not understanding the most basic physics of a motorcycle.
Jerry Spencer Jerry, I think your question is "why would you want to directly control lean angle?". Not sure this R=MPH vid directly says that, but here are some thoughts:
1-Lean angle is finite...due to traction or parts dragging. Because it's finite, the rider must set corner speed to accomodate for traction or dragging. In that case, a rider would want to directly control lean angle.
2-In racing, we are up against traction issues and attempt to run right to the edge (100%) of what our tires can offer in every corner on every lap. To stay within grip limits we respect maximum lean angle, again going back to exact entry and mid-corner speed.
3-So what this video is getting to is the fact that lean angle is finite and the way to stay on the safe side of what your traction or dragging parts offer is to precisely set cornering speed with the ability to continue to shed speed efficiently all the way through the corner if necessary, through trail braking.
I hope that helps. Many riders, after running wide in a corner and living through the experience, decide to ride slowly everywhere. That's an option. We teach that running wide in a corner is not a speed issue, it's a lack of control issue: they literally enter the corner out of control, out of the brakes...or using the wrong control, the throttle. It works when you're going slow or the corner isn't significantly tighter than you thought because you can "lean it over farther". But when the pace is up or the grip is down or the corner is tighter than you thought, trail-braking is the cure. Thanks, Nick Ienatsch

Down here in the comments lookin' for rnickeymouse like.
Yall need to just come out and say it because a lot of us are unclear. We need to UNLEARN some of the stuff MSF taught us
:-)
Just thinking, wouldn’t it be the same as saying MPH=RADIUS
Yes it would.
Thank you again appreciate it
Radius is not MPH. Radius is proportional to MPH
I’m trying to line this up with what the California super bike school are teaching. Once the throttle is cracked open....
The both seem to have some science in their explanation.
I think the CSBS is sometimes misunderstood. I think the "throttle cracked open" thing is meant to emphasize that people shouldn't twitch the throttle on and off and upset the bike with fore and aft weight transfer, at least not in an ideal situation. They do also mention in Twist of the Wrist II that for things like double apex corners and other complex situations there are times where you may roll off the throttle, stand the bike up, and/or brake before taking the next corner. I think the explanation in this video is more complete and comprehensive whereas the CSBS is more of a soundbite to keep people from bucking their bike around corners.
CSS teaches maintenance throttle so you are not accelerating but the throttle is not closed. You are maintaining speed. When you get to your point in the corner where you can see the exit, maintenance throttle allows you to smoothly add throttle without the jerky transition from off throttle to on throttle.
Thanks for sharing such insightful videos to make us better riders.
It is mind blowing that this video has only been viewed 60,000 times in 3 years yet stupid, mindless, garbage videos get millions of views. SMH
Thanks!
*deceleration
That crash in the beginning was too much throttle for that tight corner.
Those side saddle bags are low and not great fast tight corners, just my opinion!
