Yes, there is real world data, I just don't have it off hand, but I don't think that rolling resistance (as a function of the non-ceramic bearings' material) is one of the main advantages until heat and other factors come into play, and even then, it's probably minimal as compared to...

THAT"S WHAT I'M TALKING ABOUT! THANK YOU! Ok, now we're into the type of info that's helpful to me (curiously I missed it on hardracing.com, I must have just overlooked it). So a follow-up question: Ceramic Bearings. The stock wheel bearings are some kind of steel alloy (probably...

OK, I haven't articulated well the help I'm seeking - my apologies - so let me try again: Forget about counter-steering. That whole diversion started because someone tried to point out (incorrectly) that the rider pushes on the opposite handlebar, so that whole digression was just to answer...

My apologies for being unclear. Here's what I mean: At speed, let's say coming off a straightaway for a left hand turn, I would first slow down using a combination of the brakes, engine braking (also to get the engine into the right transmission gear to use through the turn, when I get back...

True, but swapping the triple clamps on a bike is no trivial task (not because it's hard to do...it's quite easy actually) because then you're messing with the factory geometry of the bike, which can lead to very unpredictable results. And even with a steering damper (which any decent race bike...

The act of hanging off itself will pull the bike in the direction of the hanging-off, which is why it helps in steering the bike more effectively. Typically a rider will move off to the side when approaching a corner, just before the corner. Usually this is done in conjunction with the...

Well, I (as are all racers) are obsessed with weight (our bodies, our gear, and our bikes). We generally concern ourselves with rotational mass and then sprung weight (that is weight carried by the bike's suspension) and then unsprung non-rotating items, in that order. So, for example, one of...

I'm not sure what you mean by "outwards." Let me give an example: On a track, at high speed, in order to steer left I will exert pressure on the left bar. So I agree with the above statement except that I and many other racers (road-racers - I race both track and off-road, and they require...

Berkeman, that's what I was hoping for - thank you. I'll proceed with this and let you know how it works for me (I'm ultimately hoping to get a simplified equation that somehow represents the different in work required to initiate a turn, so that different weights of a wheel, i.e., before and...

That's incorrect. People often make that mistake because they don't differentiate between a bike at speed and one going very slowly. At speed, pushing in the opposite direction is a technique known as "counter-steering," whereby you push on the *inside* opposite handlebar quickly to create a...

Hi, I'm hoping you kind folks can help me out. I'm a motorcycle racer, and I'm trying to find a *simple* formula for calculating how much mass addition/reduction to a wheel will increase/decrease the force required to change the direction of the motorcycle when at speed. Basically, to turn a...
