  • 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@michaelscott3562 жыл бұрын
    • @@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.

      @christopherbrau5229@christopherbrau52292 жыл бұрын
    • 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.

      @Laksujaakso@Laksujaakso2 жыл бұрын
    • @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?

    • 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.

    • @@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@Coolgamer4004 жыл бұрын
    • ​@@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.

    • 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.

      @Stratocasterhead51@Stratocasterhead512 жыл бұрын
    • 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.

  • 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.

    • 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.

  • 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.

The front tyre having 3mm and the rear having 5mm. Perfectly normal accepted practice as the rear does all the driving. 2. Made in Germany or made in Brazil ? Well Pirelli say their factory in Germany makes all the rear tyres for this model and Brazil makes all the front.
