I am a relatively new, older (42) female, street rider (4 months) and am a confident rider on my Buell Blast. It was so much fun I thought I would give dirt riding a try. I recently purchased a '86 Yamaha RT175 (was a great deal) even though it was a little tall for me (5'4"). I took it to Metcalf Cycle Park and came out feeling very overwhelmed. Dropped the bike several times on rocky and/or deep dirt hills and had to have my husband pick the bike up. I am wondering if a bike that I can easily touch both feet to the ground would have prevented some of my spills. Would a smaller bike still be able to perform in the rocks, hills, etc.? Any comments at all are appreciated. I refuse to be defeated!!!
