Tyre efficiency

That's a HUGE undertaking to present with science, there are so many variables that are beyond control.
 
That was more than I ever wanted to know about bike tires, very informative. I learnd a new useful term "tail working." Movement of the rear of the motorcycle when cornering-not skidding. The frequency range is 1-3Hz.

Finally a solid explanation for that rear end phenomenon the Rocket exhibits in certain corners. I find this when I enter a decreasing radius corner a little too upright or fast.
 
Yeah, I think it was a pretty cool little document.

Found it on a Bridgestone website... in Japan...
 
It was an interesting find Juggs, but like almost everything on the internet there is no reference to sources of Data, references etc. etc.

It's not a gripe as such, but a general observation that most things on the web are subjective or simply personal opinion - I'd like to find more information with facts and figures, not 'truths' which are subjective.
 
Gapster that article explains a lot about the whole tire thing, including the differences across the pond. On page 38 the author states, "On a m/c, the momentary countersteering push to get the machine leaning over, (a push right to lean left, a push left to lean right) relies on the shift of the pneumatic trail."

Over here we "push left to go left". :lol: :lol:

This is probably only a typo, but it is the only part of the article I understand well enough to critique, ... and it is ... well... wrong. Sorry.
 

I haven't read the article Doc, been too busy polishing. But I don't he is wrong per se, it's just a matter of interpretation. We do push left to go left, I'll agree with you on that, but what I think he meant by "pushing right to lean left" was that you actually are turning the handlebars in the opposite direction than you want to go, ie turning to the right to go left. But what the hell do I know? I've got polishing to do.
