i had a ninja 600 for a season then had to sell it due to credit card issues. i've riden my brothers R6 more than enuff times to be comfortable on it but he doesn't own that and doesn't plan on getting another this season. i'm confident that i can handle a gsxr 750 srad and that's what i'm currently looking for but i found a cbr 900RR for a nice price. my only concern is if this thing will be too much power for me? maybe i should just stick with 600s for a season or two if i cant find the 750?
