I got my 2001 KDX 200 a year ago. I put a Tubliss rear with Pirelli trials tire on the back, woods pipe, and race tech fork springs.
I absolutely love the bike and don't see me ever getting rid of it. It's competitive in harescrambles but just as happy to plod along behind the kids on a trail. And it's very cheap to operate and maintain.
