Well, here's another angle on XR suspension. Has anyone tried mounting an XR400 fork and shock on a '96 or newer XR250? I have both bikes and every time I take the 400 out I wish it were a lot lighter, but the suspension works pretty good. When I jump on the 250 after riding the 400 it feels so light and nimble compared to the 400. Then I hit some ruts or rocks and wish I had better suspension, front and back. I have been looking at USD fork conversions for the 250, but the rear needs to be higher and better as well. That's when I thought about the 400 fork and shock on the 250. It would be as good a setup as I would ever need for that bike and the front to rear balance would be right too. It almost seems like it would work without too much trouble. I know that the 400 and 250 use different size bearings at the steering stem, but the stem length looks to be the same on both bikes. They also use similar rear linkage parts, so the shocks should be interchangeable. I was just wondering if anyone here has attempted the swap and how it worked out. I guess I might have to be the first to give it a try since I have both bikes. I would eventually find used 400 parts for the conversion though, since I want to end up with two bikes in the end. I still like the 400 a bunch for more open riding, but the 250 is suck a kick in the tight stuff.
