250 to 400 Fork Conversion

Recommended Posts

Looking to improve the forks on my 2003 XR250R, are the XR400 forks a direct bolt on? Cheers:bonk:

No. The XR400R forks are 43mm and the XR250R forks are 41mm. You'll need the XR400R triple clamps, front wheel and axle (forks too, obviously). You can also replace the bearings in your XR250R wheel with XR400R bearings but you still need the XR400R axle and spacers. I am working on this conversion myself, hopefully I'll have all the parts this winter and have it done by next summer.

I have extra forks/triples in EX condition 03 XR400 (very low easy miles, my bike)

I got an extra set with a 650L I bought, I sent them out to be sprung and tuned for my weight and riding. Going to put them on my 400 and sell the stockers off it. PM me if interested.
