I just got a 2003 Honda CR 85 Expert and I feel like I'm too tall for the bike. I'm 5'4 and when I try to stand for the jumps on the track I can't extend my legs as much as I'd like. Thinking I may need to get a higher handlebar with a triple clamp-any suggestions on which one I should get? and any suggestions on any other modifications I can make to help me feel better standing? Help! new to 2 stroke and want to dial in this bike.
