i was wondering if i should buy a cbr 900 rr as my first bike, i am 20 years old, 5-7 and 165lbs..i am very confident and have no fear of driving this bike at all. All i would like to know is if there is someone that agrees with me. The bike you start out on does matter some, but what matters the most is how you drive it...if i baby this bike and the way i drive it, like i would with even a 600 then i believe i will be just fine...do you?
