motorcycle dynamics

[v65]

Pilfered this link from ST.N, looks like good reading: motorcycle dynamics.

Wikipedia is often a pretty good place to check things out.

Another web source is https://www.dinamoto.it/.

Cossalter's book https://www.amazon.com/Motorcycle-Dynamics-Second-Vittore-Cossalter/dp/1430308613/ref=sr_1_1?ie=UTF8&s=books&qid=1226376903&sr=1-1 ://https://www.amazon.com/Motorcycle-Dy...903&sr=1-1 , which is available in paperback in English from Amazon.com, is one of the most complete treatments I've seen.

I've seen this before. I was trying to work out why the rear brake provides greater stability when doing low speed maneuvres and came up with that link. Still didn't answer my question though.

Yes, I've read this and shared it with some friends. After reading I went out to the FJR and was so damn confused I forgot to put the kickstand up, and the inter-lock saved my ass. Trying to think about and apply the physics is hard for us country boys, we just wanna ride.

I would say that the rear brake isn't effecting the steering because it's just dragging the rear tire,and all the components in the front aren't being taxed(they remain free to move as designed as if no brakes were applyed).

Where as the front brake is causing,the still moving,on coming weight of the bike a lot of pressure on all the moving components that have all those nice things(bearings)that allow the bike to steer easily in the first place,linked with the rack,and other angles that want to fold under pressure.........IMHO :yahoo:

OH-yea..........V65......That's a great FYI......

Front brake also causes the suspension to dive a little, which would affect the geometry and handling of the bike. Rear brake has a tendency to pull back on the rear wheel, lowering center of gravity slightly and increasing the wheel base (making it less "jittery" when small changes in the steering are made), but even so I felt there had to be more to it than that.

Nice! Good thing Christmas is coming up. I agree with you on Wiki, the math wiki's I have read have been very good.
