Thank god a normal voice video
Yessssss
last video was like a fever dream
You loved it don't even lie
@@yammienoob no
Please elaborate, I don't understand
Glad the Honda VFR is getting lots of love in these comments. It’s the V4 bike of the masses. I love my 5th gen.
Yeah, I got a 5th gen VFR too. I love it. I think it's a sweet spot in motorcycle history.
I love my Honda VFR800. V4 for the win!
Got a 1999 this month and Yes! Yes! Yes!
I had a 1986 VFR750F which was so great. I only wish I still had it.
Forgot to mention that I now have a Tuono V4 1100 which is an unbelievable motorcycle.
@@baymoto553 I always wanted an Aprilia, but the VFR was in my price range. I can't imagine what an 86 would be like.
Love my 2014 VFR as well !
I read somewhere on the internet that part of the reason V4’s dominate in MotoGP is because part of the crankshaft is external, allowing manufacturers to add weights, which change the characteristics of the power delivery, depending on the track
Emissions is nonsense. Motorcycles represent such a small part of the problem they are arguably irrelevant. So many sexy engines no longer on the market. So much horsepower left on the drawing board. Very sad
facts
Everybody gotta do his part
I wish they would treat motorcycles as the low emission and non congestion causing vehicles that they are. Should give tax benefits, low tolls and all that.
I went from a lifetime (20+ years) of only inline 4 sport bikes. They were good. Last year I got Tuono, and honestly I’d never go back to an I4. The bottom end and midrange aren’t even close and the sound of that engine with SC project “exhaust” (it’s an open pipe with no cat), is absolute heaven. I’m biased but I bought that bike over Ducati because the sound is my favorite.
It was the cruise control that sold it for me. I got the Tuono V4 too last year. Although I will say its engine note is extremely satisfying. It’s just icing on the proverbial cake.
@@klins061also got a Tuono v4 last year. I have a triumph bobber that now sits and rarely gets ridden, the Ape is just too much damn fun
GSX-RR was crossplane design...
And ducati "superior v4" is dominating WSBK with rules that allows it 16100 RPM while kawasakis inline 4 is limited by regulations to 15100 RPM to level the playing field.... and that is for 2024 season, in 2022 ducati was allowed 16100 while kawasaki was limited by rules to 14100...
So V4 is "dominating WSBK" when you put on it 60kg rider and put 2000RPM penalty to competitor....
That is cheating in my book
👍 Good point for Suzuki motogp engine.
V4 doesn't help Honda apparently. 🤔
Ducati is winning. I guess it is related with having 6 or 8 bikes on the track (with satellite teams) and with that huge amount of precious data. Huge amounts of money were and are needed for that I guess.
@@lillaspaden WSBK organisers are doing that to make races interesting by keeping bike performances more or less equal, the thing is most people dont know that, they see "X" bike winning and assume that is becouse of its "superior engine configuration"
Doesn't really change my mind about the matter. It is cheating, however I guess WSBK don't want to miss out on a big paycheck from ducati.@@mau-ol5ii
So in order for Kawasaki and Yamaha to be competitive WSBK and Motogp should remove the rev limits on I4’s?
I have a 1983 v65 magna vf1100 and I love the sounds of it’s v4
One v4 I don't see yammie talk about or his Canadian counterpart talk about is the Honda Magna. I'd like to see some mention of this bike.
Probably not the sort of bike that fits with the channels target audience. However I own one and currently own or have had bikes of every engine configuration, single, v2, inline 2, inline 4, flat 6, triple.
Bottom line, the V4 in the magna is the sweetest of them all, I like it even more than the Goldwing 6.
There’s just something really special about the balance, sound, feel and power delivery. Oh and it is incredibly reliable too.
@@ultimateiphonedng8756 i Like the looks of Norton V4CR but its priced on the higher side & not available in my country.
how do you like the inline-6 engine of BMW K1600GT in case you have tried it ? . . . smoother than Boxer/Flat-6 of Goldwing ?
and, 90° V4 of Ducati versus 65° V4 of Aprilia ?
thanks
I am unaware of the Canadian counterpart, please tell a little more. Thanks
I had a magna that engine was amazing lots of power with high Erving engine love it and miss it
Happy owner of a Honda VFR750R RC30 for 20+ Year, I just bought a VFR400R NC30 for fun. Yes, V4 are greats !

have a 2014 vfr 800. I've sat on literally 100 newer bikes since then and never purchased one.. My V4 honda is just so damn well made.... my only dream is they make a new Honda VFR 1000 or something with a new V4 engine.
I've never had an inline 4(I know my loss) but I do love the sound the feel of the v4 in my Vmax 1200
Totally agree with other comments. Honda had it right with the VFR. I actually owned a Honda NR750 is ‘93 when I was stationed in Japan, it was ferocious.
No you didnt only 300 were made
And the nr750 was very meh performace wise compared to other 750s of the early 90s

I had a Honda V-65 Sabre for 20 years. That V-4 was a beast and extremely dependable. I put a few batteries, tires and replaced the rear wheel bearings in all those years. The thing I remember most was the beautiful sound it made. That is what I really miss about that bike. Nope, I left the exhaust stock, it was awesome!
I love this informative type of content. Keep it coming.
That was a boat load of great information. Thanks for posting it, Yammie.
Yes 👍
Really liked this clean, organized, well articulated video of yours @yammie!!
You should keep that format!
I love my 948cc inline 4, but God if I hit that lottery money that super leguera is getting parked in my bed room !😂
Z900? I love mine, too, lol... and with infinite money I'd go for a Streetfighter.
Only time I'd be happy to have a modern evaporative emissions system
I'm plenty happy with my 2012 1199, which I got for a very reasonable price ^^
One of the best Yammie vids imho. Thanks dude.
Haven't watched your channel in a while and I'm glad I came back to a technical video. Great job man!
another great vid ✨ I'm so happy you are who you are Yamms, cause I would've had a very different experience when I started if it wasn't for you
Great description and breakdown, loved it ❤
V4's are just a love letter for your ears and your guts.
Not a fan of yammies videos, but this one was solid. I learned a lot, thanks
Hey! You didn’t show my bike the 1986 Yamaha Vmaxx!!! Awsome bike that lasts forever
Hey Man, I Enjoyed Your Video. The Honda 750 Four Came Out In '69. Yeah, I Was 10 & Some Memories Never Fade. Thank You.
Love my '84 Magna!
Love mY 1999 magna also👍🏍
Presently a student at MMI. This video helped me understand a few things a little better. Thank you for making this.🌻🔧⚙️
I love my two V4s. 94 Magna and a 2014 CTX1300.
2009-2020 Yamaha Vmax. 1700 V4
i would buy if Yamaha built a 1800-2000cc V4 as an upgrade but i can only dream...on
I'm not a racer or a connoiseur of modern superbikes, but I found the science interesting. I've only owned four bikes in my lifetime, the current one being the Kawasake Vulcan S 650, but I did have one of the early CB750s when I was stationed in Japan. Awesome bike; I wish I had it back.
This was awesome. Cheers.
Great video! Makes me love my multistrada v4s even more.
Really loved an informative video like this
à truly master class explanation. not many motogp fans are aware of. thanks
The end 😂😂😂 great stuff learned a lot honestly getting more into bikes again helps my soul 👍🏼
I don't care what people say, I like the sound of inline 4 better.
One key thing that you surprisingly missed here is that the Ducati v4 engine runs backwards, I.e counter clockwise to the direction of the wheels. The gyroscopic effect of this has been amazing in helping turn the bike quicker and recover it making it much more nimble in handling. This has had a tremendous result in moto gp!
I really enjoyed watching this video when you speak straight, and to the point without all these memes and distrations.
Excellent video.
VERY WELL DONE video!!!! I love and have loved learning about motorcycles all my life and have been stuck on " screamers" for most of that time because, well . . . I LOVE going FAST, but you've educated me to think about the V4 potential. My dad bike (Yamaha FJR 1300) suit my needs for touring AND RIPPING it up but I rode my friend's Super Duke in sport mode on a twisty Colorado mountain road and was thoroughly impressed with it. Now I understand a little more as to why. Hate that you said E Bikes are coming for us all but maybe I croak before they MAKE ME switch over. THANKS AGAIN Noob!! Keep 'em coming and stay safe out there.
Don’t worry, petrol is not as endangered as media and electrical fanatics would have you believe.
Very interesting discussion of engine design dynamics. 👍
Love my 2021 Ducati Streetfighter V4S 😊❤
Well broken down in a simplified manner..love it!
its not 100% correct but sounds good.....
@@YAMR1M what's incorrect?
@@Nduthist_GP Lots of it... The V4 Ducati has a much shorter stroke and it has a much higher rev limit so it has an RPM advantage over the others. Kawasaki got its reduced rev limit back this year and won two of the races at the first WSBK round. I made cranks for a living and an inline 4 crank only has to counterbalance each piston and rod where a V4 has larger journals so has to have heavier crank pins and as a V4 has a crank like a twin cylinder engine would the crank also has a balance factor which will make the counterweights heavier on the crankshaft. To get around this Ducati had to go for a much shorter stroke to reduce the crank weight too. If an inline 4 was to run a 48.4mm stroke like a Ducati and not 55mm in the case of Kawasaki it would also rev much higher and could match the Ducati V4 for power. An engine is an engine end of... V4 on inline 4 the only difference to how much power it produces is the engine designers work and the tuner to find that power. As for how it produces power and a V4 has more gaps between firing each cylinder, that has advantages and disadvantages. Stronger pulses can kill tyres as we saw at Philip Island with Bautista losing a race due to a rear tyre.
The whole video sounds good but there is a LOT wrong with it...
I have a 2019 Yamaha R1 with a week I bought Puigs windscreen,R&G frame sliders/rear spools, GB engine coves, tech spec tank grips, motodynamic fender eliminator, integrated taillight and driven gas keyless gas cap.
Months later I got Werks USA 3/4 exhaust, flash ecu, Q5s tires, engine ice, asv clutch and break levers, driven lever guards, NRC mirror delete with turn signals, R&G radiator and oil cooler guards, front and rear axle sliders.
Right now I have rear hugger and chain cover in carbon, planning on putting more
Great vid dude. I've a 25 Yr old VFR, although has only 14k miles on it. I live deep in the countryside on a twisty+bumpy road and can only ride cautiously as many blind corners. Find just cruise it and actually behaves pretty much like a big old single with tons of bottom end torque, V4's all the way!
Have owned and run the following formats - parallel twin, in-line 4, OHC driven v4, desmo driven v4, gear driven v4, inline triple. The Duke V4S was not just hot on your thighs and legs, it was bloody painful at anything less than 75mph when the air flow removed the heat. As a road bike, it was a joke. But as a race/track bike it was supreme. The ‘Prilia Tuono Factory was a mighty fine engine, but 32mpg even when riding like your gran is not acceptable. The 675R was a peach, and matched the chassis perfectly. God I miss that bike. The inline 4s (FireBlade RRV, GSX-R K5 & L7, BMW S1000RR) are all efficient, effective, reliable, and intuitive - and buzzy. The VFR was, well, VFRy - the feel is like a long elastic catapult when you wind on the power, and the gear whine sound remains iconic. So, horses for courses, but, be very careful with those high end Dukes, and test ride the roads on a hot sunny day before you even think about buying one.
Great watch and explanation
Point and shoot the in line,, I'll keep my inline zx1400. Gen 1 2006. One of your best videos. Thanks.
Great technical video! Please do one on the triple!
Very informative. Thanks.
Excellent, thank you!
If it was cost effective I'd say v4 all the way... but having just bought an fjr 1300 rather than a vfr800, I'm happy with i4s as well.
Watching this video as we're on our way to WSBK Philip Island for the weekend :)
Where an inline 4 won 2 races... lol
in motogp the aero winglets and ride height device give ducati more advantage .
I adore my 1984 v4s x3 interceptor and Sabre are AMAZING
I love your work even from the early days. I enjoy your explanations also. I am an older biker, some 52 years worth. BTW I like your tattoo on your L upper arm, very nice. Please carry on Sir. Australian here
i think back to my first inline 4 my 73 Honda 350four. what a great little bike that i wish i still had today
As a graduate mechanical engineer who has had many bikes, this was very interesting, thank you. The bit about over-squaring an inline 4 causing it to become too wide was something I had never considered. My favourite configuration has always been inline 4. I’m 62 and this year, after a 10 year hiatus (before that I’d had bikes since I was 15) I will be buying a Z900RS as a retirement present to myself. 😊
I'm surprised the VMAX wasn't talked about. The most renowned V4 motorcycle.
Good info👍
I like seeing papa Yam growing the mop out. Also happy to see a S1K on your channel. Unfortunate you put a Leo Vince can on it. But I understand they're a sponsor and you gotta do what you gotta do. Akra, Arrow, or SC Project my guy!
Very happy to watch this for the info and the confirmation that side by side medium sized twin cylinders are a smart over all motor.
I ride my Honda Rebel 500 to work, the store, big cities, and twice now on long vacation trips. I had two new Kawasaki 500's 50 years ago when I was in the service. Now at 68 years old I bought two more midsized bikes on purpose. I have had big V Twins but they are simply not smart bikes for me anymore
. My last vaction, 9 months ago, got me almost 2500 miles round-trip to Omaha and back in very bad weather every day on HWY 30 at 49.9 miles per gallon according to the bike's electronics.
I would like to have a V4 bike, but I am happy as an old guy with a fun, fast, easy to handle, midsized bikes.
P.S. if you take suggestions for future videos, consider winter riding help. I bought a Honda 300L last September and put stud/screws in every lug for snow ice traction. I felt safe eniugh, but speed was not an option. Bikes don't plow well. Have you tried custom tire chains? Helmets with defrosters?
I made it to work every work day, but it was an easy winter and I only do 18 miles a day round trip. My Old Guy Morale did get quite a boost, when I road my winter bike to work and parked the only motorcycle at Garden Of Eden Truck Stop on a 14 degree day in big wind and snow. Yes it's true snow doesn't usually happen at 14, but it did that day.
Bye the way, ice alone is fairly easy with studded tires.
This may sound silly, but two midsized motorcycles have let me pay for the Freshman Year of college for the granddaughter. I am looking for just 3 more winters, then I will leave the snow to the young folks.
Thanks.
I had an 85 Honda VF1000R, a rolling hot tub that would redden your inner thighs after a short ride in Phoenix. Gear driven cams gave it an exotic idle sound and it pulled like a tractor. End of benefits. The earlier V45 Interceptor (750 cc) was a much better bike and I wish I had a mint condition one now. Just a different experience from an inline.
Yammie here’s a video idea. Take the bmw and a v4 bike like a ducati or Aprilia to the track. I’ve seen a lot of videos of sportbike competitions on the track and the bmw tends to always win. Would be nice to see how you do with an inline 4 vs v4. I personally think you’d do better with the bmw
Actually Ducati's 90 degree V configuration is a very difficult packaging motor due to its length & shape.If it is rotated forward it forces the position of the front wheel forward, if it is rotated rearward the CG is raised & the rear wheel rearward both of which lengthen the wheelbase. This is why the narrow bank V's are actually favored. Ducati has stuck with its traditional 90 degree L shape motor, kinda for the same reason Harley sticks to its 45 degree design. Harley has actually owned Ducati at various times in the past...
I love inline 4s. It’s the best four cylinder cost/benefit configuration not only for motorcycles but for automobiles also. It’s why so many new cars and SUVs use it.
Great vid!!
I know all us VFR owners look down on everyone but…. Yeah, they’re the best.
This video was like Papa Yamm and “not-the-mama-either” F9 had a video baby. Love it!
Hey, Yammie not sure if you will see this, but I am a beginner looking to get into riding motorcycles for the first time. I know you recommend a Turbo Busa, however there isn't a used one being sold anywhere with in the state, I have tried looking for a SV650 which I have seen many recommend, again to no avail.
I have the option of a CB500x or a Z125 for a grand less... I have never ridden a motorcycle, but am leaning more towards the 500, as I could eventually take it onto the highway. Your thoughts (or any other commenters) would be nice if you have the time.
TY 👍
The shorter crank in the V4 bikes also allows for less gyroscopic forces due to the smaller lighter rotational forces produced by the crank. This allows for a less stable, but much nimbler bike in the hands of a seasoned rider. First time I rode one I was amazed how significant the difference is at lower speeds.
Not true in a performance engine.. The V4 has to have larger journals and more counter weight as well as increased weight to allow for the balance factor needed to make the crank balance.. Its just narrower...
I'd be interested to see a manufacturer produce a 270 degree i2 litre bike. These middleweight twins just don't quite have enough power for me but I love the torque of a twin, something like the Suzuki SV1000S or the Honda VTR1000 but translated into a modern bike.
Never considered it before this video but I’m guessing that the inline 4 with the large, heavy, rapidly spinning crankshaft contributes to gyroscopic stability that inhibits the ability of the inline 4’s lean into a turn as quickly as a V4.
This changes all the time, Kawasaki won superbike 6 years in a row with a inline 4 from 2015, remember when cars started using much v4's, the inline 4 where much better
Winning 6 years in a row is a reason kawasaki now have lowest rpm limit on the grid set by rules, and people think ducati is winning because its "superior v4"
Driving4Answers and Fortnine are the 2 best channels that explain motorcycle engineering. D4A does a lot of in depth engine config videos.
D4A is goated, learned a lot from him
@@yammienoob 👍🏿
D4A is a great channel on engine engineering (not just motorcycles), Fortnine is more of an entertainment/review channel. If you want engineering breakdown on something, you watch D4A, if you want a review or comparision video, you watch Fortnine. When it comes to explaining engineering, Fortnine only scratches the surface (and sometimes even makes major mistakes) and when it comes to reviews, D4A doesn't have any.
V4s are my favorite
Good stuff!
Yammie Noob, are you one of Mulitiverse of Linustech?
Just kidding, loving this kind of set up. Watch it all the way!
But, how does the Ducati use the inertia of the v-4 crankshaft, to pull the front wheel down under hard acceleration? Do they spin it in the opposite direction?
I can't decide what I like there both sick I've had both before and loved both but I have to say the symphony of that inline 4 screaming under your butt..but the rumble of the v4 is sick to.love them both.😊
Stepped off 2 hours on my VFR1200 to this video. Yeah, once you go V4 it’s a bummer to settle for less.
We can all agree that the cross plane is by far the best sounding. I’ll take character over power 🤙🏽
There’s nothing like a 1000cc V-twin. That is if you really prefer low end torque. After riding mine, getting on a wide in-line 4 feels unnaturally wide. But yeah, excessive heating isn’t great.
As a tour operator that does a lot of track time I'll say the V4 not only represents the best on the track but also the best for sport touring in big machines like the MTSV4, which is a honking big motorcycle. We use most S1000RR on track but also use Panigale V4 and V2 as well as R1. The S1000RR is easiest to ride, and makes it easy to work on your riding rather than futzing with the bike. The R1 has character and might be more fun but isn't as smooth so it comes down to rider ability mostly. The Panigale V4 is an absolute beast that will shred the lap times of the other two but it's not very forgiving.
With regards to power pulses on the rear tyre, what’s the difference between the Ducati V4 and the Aprilia V4?
Inline 4 motorcycle engines were being used around 100 years ago.
Two out of the last three MotoGP winners (Quartararo and Mir) had inline fours. In the last 10 years, seven World SBK champtionships (Rea x 6 and Razgatlıoglu x 1) were won on an inline four. I'm not sure I can agree that V4's are unbeatable. And this coming from someone that used to own one.
Now here's something I'm sure we can all agree on: Aprilia should have an RSV4 1000 so they can compete in World SBK.
If you're going for ten years in WSBK, then it should be the same benchmark for MotoGP. Only 2 inline fours in the last decade have won MotoGP. Yamaha won twice, and Suzuki once. That's seven out of the last ten MotoGP Champions on a V4.
It should also be noted, in WSBK, Ducati still used V twin engines until 2018, when Aprilia left. So for that decade you refer to, with the exception of one year, there was only one V4, Aprilia until 2018, and Ducati from 2018 to present. The grid was overwhelmingly Inline 4 for those ten years.
Jonathan Rea winning six of the last ten years in WSBK, is arguably more about him as a rider, than it is about Kawasaki.
Had to add 2 cents, because to make your point, you left out any information that might go against your narrative, or as they say, "cherry picking".
@@JohnDoe-zo5tu I agree, wish they would come back.
Pecco... Ducati - 2022 and 23 MotoGp Champ.
Always cool to see a bandit mention
A lot of what's "Winning" on the track has a little bit to do w/ the weather, the tires, & like the rider who harnessing all that as
he hangs on for dear life? Who knows which motor is the absolute best & why does it really matter as long as you can get
up to 180+MPH when the cops flip on the lights? Besides, I'd bet a champ racer w/ a much smaller bike could wax Yammie
on his 1000RR..... so it really doesn't matter to the squid. peace & be safe
I prefer the high revving I4 sound but thats me. Love th sound of My FZ6 S2. Prefer it over the FZ1 that i also have.
Que bonito ver un frame de todocircuito
I still have my 5th gen VFR800. Love the engine just wish it could be lighter.

The primary advantage of a V4 over a L4 is rigidity. High speed engines run up against intense vibrations from both firing order or primary balance and secondary mechanical balance this means strength is not the limiting factor but dimensional stability, stiffness, as it minimizes strain, which is related to fatigue by reversals inherent in vibration. The V4 configuration, it also shrinks the dimensions of the engine and all its components which increases rigidity, reduces strain, increases specific strength, decreases mass, and further reduces secondary imbalances of the engine. The V4 over the L4 makes layout and manufacture more difficult. But the V4 does not magically increase power production and may limit it by retention of heat. So you spend your money and take your chances hoping it works out. Personally, Honda’s long skinny crankshaft seems to me subject to more torsional fatigue and strength issues as it has less rigidity than a short compact V4 crank which increases and related to strain reversals of the material in the L4 over the more short and stiff V4 crank.
Nice outro. Now i can't sleep at night
I love my KTM V-twin, but I do love me a good V4. If Ducati's weren't so much more expensive, I may have just bought a Multistrada over my Super Adventure, but the Multistrada was an extra $10k. I love me a V4, but not $10k more. It's ok anyway, the extra torque on the V-twin is more useful anyway. =)
How about some audio of a decat and race piped V4?
Lots of the I4 audio you used in this vid is decat/race pipe. I wonder why? 🤔
I4s are almost twice as wide as a V4. Longer crank of I4 is heavier, and more prone to cracking due harmonics.
