I have an 85 LT250r and I am looking to rebuild it. I am in need of a frame, swingarm, axle and many other parts. Ebay has done good for me and now this site. My question is, What years are interchangable? If I come across an 86 frame, will all my 85 parts fit? I always thought the 85 quadracer came out and then in 86 they made some major changes. Then I was told that 85 and 86 were the same, but most of the parts I have looked at say they are for an 86 to 92 250. Any info would be just swell! Thanks in advance.

 

They are the same, the year they made the changes was in 87, and then again in 88 and 91. Good luck with your rebuild.

 

as for the changes by which year (as i understand them):

1985-86....
introduced & stayed the same machine

1987...
motor: power-valved engine, reed cage moved & is more accessible
front suspension: reinforcements, gussets, changed A-arms & shock mounts
rear suspension: geometry the same, changed the axle bearing carier to the square one

1988-90....
motor: changed reed cage & the cylinder slightly
rear suspension: changed wheel bolt pattern to match LT500, 5- 130 bolt pattern

1991-92....
rear suspension: new geometry, more like a current MX bike, moved air box from in front of shock to behind it, (by necessity.)
front suspension: a few more gussets to reinforce were the factory thought was weak

the only complaint i have is that they never made a real mount for the front bumper(bolt holes, etc.)
