I feel fine about rebuilding a 2t, but wont be doing that work on a 4t myself. I dont put many hard hours on dirtbikes, so im not that concerned about 4t maintenance as long as i get a good one. A crf450x would suit me fine, but not the price. Ill probably pick up another cr250 with a green sticker and call it a day.
Aaron, I think you have the right idea. Even if you put low hours on each year, a 4t that old is always kinda a big question mark maintenance wise and could potentially surprise you with a really expensive repair bill. Also, I honestly don't feel they were great bikes until later years.
The 2002 YZ250 is my choice as its the last year of green sticker and everything from 2020 YZ250 bolts right on including the current bodywork. Its basically the same bike including engine with a steel frame and open chamber KYB forks (not SSS KYB.) 1999-2001 shares the same engine but different frame and body work, 1999-2000 different carb, the Keihin PWM which is know to be more finicky than the PWK used from 2001 to present. 2002 is really the unicorn for green sticker. :thumbup
I've always wanted to own a RM250. They really do handle better than just about anything from that era and look fantastic.
Have you considered a KDX200 or 220R? For offroad riding, they really are great and dont take much to dial in. Frankly for the riding I do, it would fit me just fine. Unlike the MX bikes that take a bit of fiddling and tuning to work well on single track, the KDX does it out of the box.
Or a 125? I've been noodling picking up a YZ125 to convert to YZ125X offroad type specs as a fun project and ride.
Then again, as you already have and know the CR, just grab another one of them. Green sticker 2 strokes of that era arent cheap anymore, but still a better buy than a fourstroke of that era in my opinion.
