My situation: i am around 5'10", 170lbs, formally raced motocross and now i would like to buy myself a street bike. Do you guys feel 600cc or even an 650cc bike is too much?
Not at all. I'm 5' 10" 165 lbs and started off w. a 600 katana. Now have a 600 yzf-r. Really no need for a bigger bike unless you weigh over 200 lbs. The 1000's just wana pop the front end up everytime you get on it if you don't weigh that much.
