This KTM Is clean but old. My son does not race but rides quite often. I just replaced the top end before the winter. He has now out grown this bike and has moved up. I have completely went thru the bike and replaced any bolts, parts, bearings, chain, etc.. when i first bought it. It has been a great little bike for him. He is 11. Ready for Christmas!! Everything except the pipe is stock. The top end is stock and OEM. We run 40to1 ratio.
