My son wants to start riding. He is a 9 year old, who is athletic and picks things up pretty quickly. I originally wanted an rm85, because he won't grow out of it too quickly, and it's the only 85 with a powervalve to broaden the powerband. But then I thought it might be too much for him and considered a klx110 because it's an automatic... but I eventually want him to learn a clutch as soon as possible. Would a crf80 be too shortlived because it's lack of power??? Or, have you heard of people getting a throttle stop on the 85 two strokes?? Anybody our there have this issue with their kids in this age range? I would appreciate your input. Thanks.
