Best race bike:
Honda's NSR500 with Mick Doohan riding
70's era Kawasaki triple with Duhamel riding
70's era Suzuki triple with either Gary Nixon or Barry Sheene riding
Best street bike: Suzuki's triple
Best two stroke failure: Bimoto's 500 v twin (pretty, but not good on the street)
Because I only ride in the dirt by mistake, I have no idea what a good 2 stroke dirt bike should be.
