First off, they are not crotch rockets, if anybody that rides hears that coming out of your mouth you'll either get laughed at or smacked. And i would not recommend any new bike over 599cc to anybody that has no clue what they are doing. if you're set on a 6 or 7 better start looking in the early to mid 90's. they were heavier and didnt have the power that todays bikes do.
