miscellaneous motorbike geek stuff

Bookmarks are so passe, and don't automatically turn into google fodder. So here are a few links which ten years ago I might have bookmarked.

Overview of MotoGP engines (drool. Shame FIM are are going to strangle MotoGP).

Some papers on the physics behind some of the typical loss-of-control scenarios faced by motorbikes: thrust induced highsides (the common reason for "high side" crashes - the most painful way to crash a bike without hitting anything but the ground, see this animated gif for example.), brake induced highside (as can happen when racers "back it in" to a corner, rare type of crash but happens, eg Haga a few seasons ago at Welkom), and another similar paper which also covers "low-side" brake-induced crashes.

Paul, The tire companies can't keep up with the loads applied during MotoGP use. At Loudon in 1979, 'Not-a-Goodyear' (unmarked) tire dispatched JCA in turn two during final practice. In 45 minutes we rebuilt his bike from Lyle Newton's factory new YAMAHA then raced on with a broken right wrist (AMA was NOT happy, pulled JCA's competition license later.) Finished forth to Mr. Spencer (Kanemoto YAMAHA) in the final before 'conversing' with a CYCLE magazine writer playing racer for the weekend. GOODYEAR and I had a 'very heated' discussion about experimental tire testing on a race weekend.
