I just bought a 1989 RMX250 that is in excellent shape and was wondering if $675.00 was too much? By the overall shape its in (still has kickstand), I would guess its on its original bore and its a screamer! I believe its original except the rear fender and the exhaust. I think I got a good deal. What do you think its worth?
If mechanically sound, worth every penny of what you paid. Once you start paying three figures for bikes, you usually get a pile of pieces waiting for lots of money and attention. Enjoy!!
For that little money I'd try to find some parts and get it rebuilt before you grenade it. You may be right about it being original internals. It looks like it's well worth the investment!
