i have an cbr600f4i trust its more then enough power to throw your ass back in the seat well at least for myself im 5'8 175 and my ass leaves the seat in first, second, nd third when i crank up the throttle.. bikes very smooth and easy to drive extremly nimble, and riding position isnt to bad either on your back or your wrists unlike the 600rr so your back will be thanking you later..
also i got my gear before i even bought the bike.. helmet, gloves, jacket, nd boots... thinking bout some pants pretty soon..
but welcome to the addiction
also just a quik question how in the hell are you 21 and drive a viper??
