Motorcycles are fast because of their power to weight ratio.
The 2004 Yamaha R1 (yes its stupidfast) weighs in at 170 kilos and has 176 horsepower.
Thats FAST!
Its like M3 with 1385 hp+...
... a 600 cc is less powerfull, but still insanely fast. A good starter, "sporty" bike could be the 400 cc honda NSR, its gone out of production dunno if u can get it in the states at all do some research ... i guarantee you speed !!!!
