fast bike with allot of go go go . . usually rules the streets , drag strip , and the track because of it's high weight / power ratio

A Japanese motorcycle. By default this is state of the art, fast as fucking hell, and will blow the doors off ANYTHING ELSE on the road.
Suzuki GSXR1000, Yamaha R1.

A rocket with two wheels, one of which is often not on the ground due to high power/weight ratio, that you straddle and zoom all around slow moving boxes on wheels.

A sport bike, usually japanese, but somtimes italian, rarley german (the new BWM K1200R) or american (buell) The minimum that really is a crotch rocket is along the lines of the classic 2 strokers like the RZ350 or the NS400r, cominng up to the the pinnicle in the likes of the RCv211 or the yamaha M1. More common examples are along the likes of the ninja/GSXr/YZFr/CBR series.

Very fast, even the slowest of these (the RZ350 and NS400R) can run times in 11's in bone stock. with somthing like a turboed GSX1300R hitting 7's.
Did ya see the turbo busa video where the crotch rocket rips a big ol viper a new asshole?
