A rare youtuber who didn't ask to subscribe and like the video, but rather earned it.
He gave me $5 to subscribe, you lost out
Yup, and I'm finally committing! Watched enuf vids to like em all
So true @Daman Jeet. This guy is on a whole different level. Even if throws out random "nerd" stats as some would say, everything he says and represents is on point. Nice video @fortnine
I make it a habit when the first thing they say before the video even starts is to subscribe and like the first thing I do is dislike
@@dhruvadj agreed bro
Tires. I once heard that manufacturers had three requirements for tires - round, black and cheap. And that they were willing to compromise on the first two.
My entire riding time over 40 years only had one tyre requirement.................Must be cheap.
That describes all the girlies in my neighborhood.............
@@jcwoods2311 Boom boom tish.
Most people have no idea what tires are for, much less what makes a good or bad tire.
I think that was true thirty years ago. My last three motor vehicles, car and two motorcycles, have all had good tires. Maybe not the ultra premium stuff, but good tires.
I am an engineer, I couldn't agree more, you earn my subscription and respect, nice charisma and confidence in front of the camera 💪
Charisma
Wow you really fail as a engineer huh, couldn't recognize that the linear graph is of a electric motor. And that what he said about tyres is bs
Tell us MORE, ubdhav!
@Adrian Dobre Huh, an engineer that can’t spell, ‘Charisma’ You can declare anything you want in text. Doesn’t make it true.
@@udbhav122351d you spelled tire the un-American way, opinion disregarded
Love your content. Clearly put a great deal of thought and effort into it. Probably the only detail I would throw in there to tie two of the very astute points you made is that what you "feel" is acceleration. Acceleration is effectively how readily available power is at the current rpm, vs. how much mass (you plus the bike) you need to move. Thus if you have two bikes with identical powerbands across their rpm range... and one of them weighs 550lbs and the other 350lbs and you weigh 150... then the lighter bike will accelerate ~30% faster and you will feel that.
If you currently weigh 250lbs... let this be an incentive to you to get a massive free performance boost from your bike. Unless none of that matters to you...I'm at 220... so... it kinda matters to me... but I just ate another chocolate chip cookie sooooo....
Great advice at the end, try the bike, ride what you like.
Except for the fact that there IS no "current" RPM or speed, because, by definition, it has to be in a constant state of change (i.e. INCREASING) or there would BE no sensation of acceleration.
@@michaelscott356 I get what you're saying however you can determine instantaneous acceleration for any combination of rpm, gear, and speed at any explicit time.
Otherwise you wouldn't be able to generate a plot of acceleration from 0 to top speed. I.e. just because everything is changing doesn't prevent the ability to measure it or feel it and learn to keep things in x power band with y throttle to power out of a corner predictably.
You can't make acceleration comparisons only based on power to weight ratios. Aerodynamic drag is an important factor too. At high speeds that 30 % could be a lot less or a lot more, depending on the shapes of the bikes and riders.
@Janne Laakso I agree, go fast enough and drag literally and figuratively becomes the great equalizer.👍
Having said that, of course I can make acceleration comparisons, by keeping it basic. The whole "assume a frictionless spherical chicken in a vacuum" thing. Otherwise we get into wheel mass and radius, drag, etc. Even then our model won't be 100% without some empirical fudge factor.
Getting up to typical road speeds, wind drag with similar styles of motorcycle isn't the dominating factor. That's where my head was at so I ignored it. Already near highway speeds and faster then yeah it would definitely matter if one chicken was more slippery than the other. 😉
If what we feel is acceleration, and acceleration is proportional to torque / moment of inertia, the latter of which is constant throughout the RPM range, does that mean that we should look at the torque curves when comparing the enjoyability of two bikes?
Always something to learn. For anyone asking, from here on my weight is “without fluids” . . .
What do you mean overweight, I only have a dry weight of 45Kg (99Lbs),
Bart Bevelander technically 98 percent of your body is water, so maybe more like 2 pounds
And after taking a dump, too. And no heavy thoughts.
Freedoms Patriot 60% Of body weight is Water
Walter Wilkins
If you really want to tighten up your numbers, get rid of pounds or kilos, use Stone... I weigh under sixteen and a half (16.43) stone..... yep, I’m one skinny bitch at 230 pounds.... uh, I mean sixteen and a half stone....
The "Torque vs. Horsepower" game is played with car manufactures as well. Nice explanation!!
The video also deserves a follow up on how difficult it is to have standardized engine performance graphs for objective comparisons because different dynos have different accuracy/drag/cooling etc and the performance of an internal combustion engine at any given time can vary substantially with atmospheric conditions.
Some people go apeshit on internet forums comparing bike/car A's dyno to bike/car B's dyno to establish which is superior based on a graph from dyno model X tested two months ago in one city and dyno model Z tested last week 3000 miles away, none of them stop to realize that each of those graphs could be like 5-10% off easily.
Some manufacturers do provide the full engine performance graphs, for instance Ducati and BMW do, but they are the "indicated" performance graphs (basically the theoretical ideal performance expected based on measuring/simulating the gas inside the combustion chambers) not actual print outs from an engine dyno test, largely because there is no universal industry standard equipment and test conditions for that so that could easily be fudged too.
torque vs horsepower is a fallacious arguement since they dont oppose each other, you really want to get the most of both.
honestly torque doesn't come into play unless you are trying to move heavy objects. when it comes to a bike hp is all that matters. when it comes to a semi torque is all that matters.
@@leetucker5788 no. Power is always the number that matters (for engines): torque can be converted, a gearbox, a torque converter, even the wheels itself does nothing else than converting revolutions and torque.
But the power will be the same on both ends.
when you put all your weight (i take mine ~100kg) on a lever of 1m, you are generating 1000Nm of torque!
but even the engine of a 125ccm-Bike (~10Nm) will (with correct gearing) turn you to nuts, because it has way more Power!
@@Coolgamer400 Except you're comparing static torque vs dynamic torque (and static torque, because in car or a motorcycle both are involved). That's useless comparison. You can read up on that. You can also read up on the issue of torque conversion. Yes, you do manipulate torque with various systems - like torque converter, gearing or wheels. However, all those elements are limited by other practical factors. If you go for really extreme gearing you'll be restricted to extremely slow moving vehicle. Torque converter's torque multiplication is limited by among other things size of it - and generally speaking isn't most efficient way to doing it. Similarly manipulating torque through wheel size is limited by shape of vehicle.
That's why torque as maximum value is important, but more important is torque curve. If your engine produces 10 Nm of torque, it might be in - say - 6000-6800 RPM band. If that's the case to maintain acceleration you need to constantly shift gears.. but you can only have so many gears (since it's simply limited by physical space you have for your gearbox). More importantly you lose time with each gearshift as well. In other words: the higher your engine maximum torque is, the flatter the curve and lower revs you get (close) to the top of it, the less compromises you need with gearbox and wheels.
Power is important as well, and honestly all factors have to be considered when 'judging' any given drive train (since engine is only part of entire system). Still, the point of start is engine, to which you adjust all the other factors to achieve desired results. Choosing wrong engine for application is just idiotic.
Finally, someone who seems to understand torque and hp!
Instead of the usual high torque engine is slow revving motor, high hp = speed.
The torque curve tells much more about an engines performance then many realise
Or, THAN many realize. :)
i mean im pretty sure he has a physics phd so that helps alot
@@burdazza2711 I dunno, theres far too many 'smart' people that should know better that insist that you need back pressure in an exhaust or you lose power...
"what most riders desire is..."
except when reviewers actually get bikes like that they call them boring o.o
Bingo.
This is true for cb500f and e, for example
Aw shucks, consistent and predictable power. Boring. /s
Not quite. Reviewers are almost invariably biased. In the Uk, if Triumph makes a bike with a smooth torque and power curve (lets say speed triple) it is a refined, smooth and linear engine. When kawasaki make a Z900 with an immaculate power curve it "lacks character".
Best advice is, as Ryan says: try the bikes out because 99% of reviewers speak bullshit.
Ah, the age old problem of "reviewers" aka advertisers. More often than not any "review" you see will have loads of positive aspects and praises of a product with just a dash of the negative sides. Some may even feel like tech sheet readouts. In these cases you have to remember that they are very likely getting paid directly (sponsorships etc.) or through referral systems (sales volume). So if you come across with "reviewer" which always ends with a positive image of the product, you know that the person is financially constrained in their "review" and you should mainly focus on the negative sides of the product brought up. These "reviews" are one of the reasons why user based content has been in such a high regard, people want to cut through the manufacturers' and "reviewers'" bullshit and know if the product is actually any good.
You know who would never trick you?

Thank you for explaining the tire codes. I usually get caught up trying to hunt down the OEM version of whatever tire my bike came with thinking it's better, but now I know it likely means the opposite.
Won’t always be the case. Which is why research is important.
This is the nerdiest motorcycle video that *an* enthusiast can watch. Measurements, law, and physics. Thanks.
Refined comment:
This is a very academic and informative video that most motorcycle enthusiasts can and will appreciate. The richness and diversity of subjects from mathematics to regional law are very detailed and informative. The

We don't all have to be as smart and clever as Ryan FortNine. We just have to enjoy his antics and understand the points he's making.

@@hungwasson1399 Completely agree
By the way, I've seen some videos of Ryan making fun of himself where he had clips of him as a "stand in" model for motorcycle gear - jackets etc. - do you know, did Ryan used to work for one of the motorcycle retailers? If so, which one? I'm curious.

Thanks for an honest explanation of the correlation between HP and torque. You explained it clearly and in simple terms.
As ever - brilliant video from you guys and some great marketing debunking done! Thumbs up from me!
Think you might want to watch Stuart Fillingham TH-cam video on these tyres, totally different perspective with thorough research, hope this helps. 👍🏻
Bullshit! front tires have 3mm, REAR tires have 5 so you were comparing front and rear. Pirelli has factories in different countries Brazil, China, Germany etc. same tires. Sloppy "research" You should be ashamed Fortnine! See this video th-cam.com/video/YYXx9ogQ0lM/w-d-xo.html
Re the tyres, what a load of bollocks. Comparing front tyre tread to a rear tyre tread and factory that makes crossplys to one that makes radials. Investigation powers of a shopping trolley. Never let the truth get in the way of a food conspiracy theory eh!
TMF, Ryan does a lot of great work, but he might be way off on the Pirelli tires in this video. You might not want your approval stamped on this one.
...hmmm...and I thought you were one of the smart ones...
This is the adult equivalent to your favourite science TV Show you never wanted to miss as a kid. :D
I really dig seeing all the formulas in the vids. Helps me (and others, I assume) clarify some of the mysteries of riding and all it encompasses. Thanks guys!
Gotta luv a video where Ryan does the math! Great info, and I agree with..."just go ride, feel the tires, feel the weight, feel the power ...." etc. Every bike I have owned and rode had enough "power" to injure/hurt/kill if not careful. Another valuable video, thank you!

Thank you for your no nonsense approach and informative yet entertaining content. It is very much appreciated
made me laugh in less than 7 seconds, and then dropped real knowledge. I love this channel.

Haven't ridden for a few years now, but I love this channel. It's holding me off until I can buy another bike. Great work.
I really enjoy your videos. The quality and effort, your eloquence and vocabulary, but above all the sheer amount of hard knowledge they provide. Fantastic! Keep it up!
I have only one way to judge tyres : user review through motorcycle forums , they are the only review I trust .
Computer parts manufacturers have been caught using sweet tech deals for certain users to post positive content and reviews for their products on many forums,
it wouldn't surprise me if motorcycle companies did the same.
forum yes amazon dont trust.Too many fake reviews at amazon in fact there are companies selling this service to others fake reviews.

Well the motorcycle cannot have its own motives or intentions so you are the only variable, while in a relationship there are two or more variables.
That's not a girlfriend, that's a narcissist.
Honestly, after being on the web for 25 plus years (not counting the squeeling modem BBS years), this has to be one of the absolute best and most informative vids I've seen so far.
My hat off, not only for the information but also for the born-to-be-an-informative-and-easy-to-listen-to-guy who explains it all.
Good one as usual. Wondered how Enfield put Pirelli as OEM fitment against Metzeler on my Thruxton. Which was worn out in 9000kms anyways

Hi, after binge watching all, yes ‘all’ of your presentations over the last few weeks... as a born again mature rider from the UK, I have really enjoyed every one. I have done the research, got all of my gear, and my new bike is on order too. Keep up the great work.
What you getting then?
Luke McGowan... you may laugh... its a Zontes Phantom 250s. Was £3k new but got an ex demo model direct from Zontes UK, with 270 miles on it for £1500 with MOT and service, delivered to my nearest dealer about 40 miles away. I’m getting it next week... just to get me back on a bike again after 10 years... will have to see where we go from here. Cheers.
Just such good advice - it's taken me four years to figure out that riding a bike is the only true way to understand what it's like 🤦♂️
Thorough and entertaining.
Excellent.
Back in my courier days I put some (slightly) used, very sticky German rubber on an MZ 250 2-stroke single. It was TRANSFORMED. A commuter Putt-Putt become something I could throw into bends. I didn't know about the trickery with OEM tyres, but high-end tyres on an old bike do take it to another level.

you can find torque graph for your bike by looking for aftermarket exhaust, they will put stock and aftermarket to show you how the fake carbon fiber can give you 5 hp at the top end
cosimo ricci at the cheap price of $800 or $1500 of you add a tuner..
A lot of the dyno numbers and charts thrown out by aftermarket parts sellers are pure bullshit, just like their claims of gains.
Without tuning the ECU or other things, horse power gain in nothing more than pure marketing smoke, there is no proof that it automatically means more power, in fact it is more probable you lose than gain, so those graphs may also be a deception
@@alexduey7868 The guys commenting on your suggestion missed the point.
Sure, there might be a 5HP difference ehre or there, shure it might be total BS. who cares. at least we got to see a 'relatively accurate' graphical depiction of the power/torque curves, which was what the OP intended. It's a lot better than seeing a 'peak' number.

Thank you for saying how listing only peak torque is useless. We need to know a lot more to get an idea of what the bike is like.
I think Ryan summed it up perfectly at 09:34: "...salesmen are salesmen, so just go ride". For most motorcyclists the choice of bike is an emotional one, with a little economics thrown in. So what the thing feels like, on the road/track/trail and beneath your backside, is probably the most important consideration.
The best motorcycle content on youtube. Thank you very much from England. 👍
I have watched a half dozen of your videos and I LOVE the content. Excellent work and never once have you asked me to subscribe...so I did. You are doing good work here. Please dont stop...
What Ryan may have forgotten to mention is that when a manufacturer publishes HP and torque numbers, or even the complete charts, they measure the engine output at the crank, bolting the crank directly on the dyno. Thereby bypassing the power losses in the primary drive, clutch, gearbox, and final drive; those usually sap around 15% of output.
This means that 5 kW of power (peak) is dissipated into the drive train of a Ninja 400. That's a lot of heat and noise
The information nobody knew they needed to know!! You’re badass!
Well done, your demonstration and delivery are excellent. Thank you for your informative videos.

7:42 "and when torque is moving, that IS horsepower. One is a function of the other". I've tried to explain this so many times, so many people just can't understand it.
Torque and horsepower are the same on a graph at 5252 rpm. Race engines want high power just below the redline. Street engines want lots of torque from idle to 30 mph, 60 mph and to 80 mph. The power for a street engine near redline rpm is useless, especially if it gets 5 miles per gallon or less to do it. See a horsepower and torque graph for the new Goldwing- very good for public roads, for a high price.
Torque tells how much work can be done.
HP how fast work can be done.
Electric motor gives max. torque all the time from 0 RPM to max RPM, but zero RPM work will never be done.
"But muh torqueeeee !!!" always seems to scream louder than any sane explanation.. cant win all battles
Torque is just a fancy lever. Alone it can't do much.
@@XtreeM_FaiL it is funny that Harley Davidson advertises torque, and everyone else advertises horsepower. To me it is more about price, weight, reliability and comfort. I am most attracted to the inline 3 Yamahas, but own an older Kawasaki ZZR600 inline 4 for 75 mph, and a Honda Shadow 600cc VLX for 60 mph.
Excellent videos!! I love the physics, humour and details you introduce into every one of your videos!

"Trust me"
😐
it's hard not to respond to the name "liberalsarecriminals" without going ballistic , but I won't cuz that puts me in the same class as you. I guess I'll just keep thinking about stuff with an open mind
It is important to pay attention to both torque and power because the former tells you the output of the engine at low revs and the latter at high revs. Of course having full output graphs of either measure would be preferable, but so long as manufacturers like to list peak figures only, you must pay attention to both.
Not quite. Torque tells you the potential work that can be achieved.
Horsepower just tells you the potential rate by which that work can be achieved. Potentially.
What matters is what can be achieved, it's rate of occurrence only comes after that first initial delivery of TORQUE to act on propelling an object from stationary. Potential to kinetic energy.
Nice explanation about torque and horsepower. I always enjoy watching your videos.
A truly great video, honest, not too difficult to understand. (need to watch it a few times to get my head about the formulas)
9:03
What most riders unknowingly desire is an electric motorcycle.
Exactly! I was surprised he didn’t go there at the end with that constant torque graph.
wrong, electric motors have the peak torque at 0rpm, the faster you are spining the motor you feel less torque, the power delivery is similar to a capacitor
Recorded exhaust sound?
@@Erickzy This is not true of brush less direct current motors but I dont know of any EVs using those.
@@Erickzy Not true, electric motors maintain their torque across most of the rpm range than drop off at the end. If you imagine it graphed it is a horizontal line then it drops off at the end.

Your videos are highly entertaining and informative. I'm glad I found your channel!
Thanks for helping me not be duped on the lot. Superb as always, cheers.
Wohooooo 3 minutes and i am here best way to start my evening
4:43 I don't know whether to applaud you or roast you for using the SI "micrometre" instead of micron, all while standing in front of a blackboard dirtied with measurements in pounds. (As always, though, impeccable production. Thank you.)
Roast me. The imperial system deserves no mercy. ~RF9
omg I have only just found you, hilarious, educational and bang up-to-date... thanks for raising a laugh every time. Love your work!
I would love an episode on aftermarket tyre choice- being an adventure rider - trusty DR650- what are the points we should watch after? Love all the info!!
Ryan you need to check out Stuart Fillingham's video from earlier today disputing everything you said about Royal Enfield and Pirelli tyres
It turns out the Pirelli Phantoms have 3mm tread depth on the front tyre and 5mm tread depth on the rear tyre no matter where you buy them from.
Unless the front and rear rims are different sizes, it is an extremely poor decision to manufacture or require different tread depths front and rear. Imagine if a 4wd or AWD did this? Yes, most supercars have different tire sizes front and rear..
@@hillaryclinton2415
The front and rear tires are, in fact, different sizes and it's fine for them to have different tread depth. The rear tyre being the drive tyre gets a deeper tread because you want it to have more grip for launch.
Also the tyres having tread depth being a bad thing was never mentioned or even a point in Ryan's video.
There’s more to it than that. Ryan also compared an expensive German-made radial to a budget cross-ply. Yes, they’re both Phantoms, but they‘re intended for classes of bikes with massive differences in weight and horsepower. Not to mention tube VS tubeless rims...
@@hillaryclinton2415 wrong... uneven wear due to more drive from the rear... bikes aren't AWD... AWD/4WD cars are.
@@Strideo1 Obviously you know nothing about thread depth and grip.
Absolutely brilliantly served up in full.
Thank you,as always entertainingly brilliant...
Awesome video and excellent explanation of the "max" HP and "max" Torque data advertised by manufacturers. Thank you!!!
So glad Ryan didn’t take a long break like last year.
Unfortunately, lots of dealerships don't allow test rides...
wtf dealerships are you going to? idk about where you are but i haven't been to a single dealership here in Australia that doesn't offer test rides. How the hell are you supposed to know if you actually like what you're buying if you don't test ride it??
@@lalnablehector1285 welcome to the USA, where you can walk into a dealership and be told there are no test rides allowed, or see the salesman clipping his nails on his desk instead of getting up and asking you if you need help (actually happened)...
@@lalnablehector1285 Here in Belgium the strange thing is to find a dealership that allows test rides, they often don't even have bikes to test and if they have its only for the most popular models, so your choice is extremely limited, you either ask a friend or someone to try their bike or you have to rent...
@@adridell what the hell sorta dealership is that?! with that attitude they don't even want to sell them by the sound of it.
@@lalnablehector1285 Belgium is a very small country with less than 500.000 registered motorcycles in total, there are very few official motorcycle dealerships because it is very expensive and there is not enough demand, it's often independent motorcycle repair shops or other that work in cooperation with big companies like yamaha or honda and can get official bikes for display and parts for repair. There isn't even enough demand to have an official dealership so even less budget for test rides. That is just the reality of it, doesn't mean there is no way to test bikes its just not as easy, it's not really their fault if there is no profitable bussines, that unfortunately how the world works...
I absolutely suck at math but I literally followed that whole equation as it was explained.
You are impressive Sir ~
Fortunately, there are Dyno analyses of several models out there. Congrats again!
FortNine and commenters please refer to Stuart Fillingham's retort to the claims about the Interceptor's Pirelli's, "News on NORTON and Pirelli Phantoms Sportscomp tyres. Is RE tricking you?" It appears that Ryan may have goofed and compared an over the counter rear tire to an OEM Interceptor front tire. All Pirelli Phantoms apparently have 3mm tread depth on the front tires and 5mm on the rear no matter where you get them (OEM or over the counter). After doing the necessary research, Stuart pointed out that the Interceptors have spoked wheels and thus use cross-plain ply tires. He found out that the only Pirelli plants making cross-plain Phantoms are in Brazil and Indonesia. Radial Phantoms are made elsewhere.
It seems this issue should be revisited.
