1982 XC vs WR frame

I have an 82 250XC complete. I have an opportunity to buy an 82 WR frame and swing arm CHEAP. Is there any difference in the frames / mounting brackets etc? I'm not sure the engine size that the WR was.

Frames are the same. Swingarm and forks are different for lower seat height. You could use your XC forks (same as CR) and slide them up the triples.

There are two reasons I am doing gonna buy it. First was it never hurts to hoard parts for your old bike, especially when you can get them cheap. Second, the guy who had my XC cut off the mount for the kick stand to ride MX and the swingarm for the WR still has the tabs to mount the kick stand. Third, I can go ahead and paint the frame and swing arm and just switch parts over as I restore it.

What is the difference in the swing arm? Is it shorter to give the WR a tighter wheel base and lower stance?

Shorter WB and the shocks I believe are mounted further rearward if I remember right.

I have (3) 82 frames, 2 WRs and 1 XC. The swingarm is approx. 1 inch longer than the WR swingarms and is the same swingarm for the CR. The shorter swingarm on the WRs accounts for lower seat height,less rr wheel travel, and slightly sharper turning over CR and XC models.

Interestingly the distance from swingarm pivot to shock mount is identical.

Cool, well for riding here in FL the shorter WR swing arm will actually be a benefit.

Thanks guys!
