I am a novice-intermediate rider, 5'7 158 age 38. I ride 60/40 track/trails. I currently have an 02 KDX 200 w/ FMF Rev pipe & TCII SA, Race Tech front springs .42 w/ gold valves and stock rear .50 w/ gold valves. The bike is great and it has been a lot of fun, but I was thinking of doing a little MX racing, vet class for fun w/ my buddies. We're all older and don't want to get hurt. I'm looking at getting a 00 KX 250 (ex cond/good deal $2,500) and was wondering if it will be too much bike. Can I still enjoy and lug the bike on trails? Or would a 125 be a better choice because less powerful than the 250. Let me know your thoughts on the 250.
