Rememer how well Spud Walters did with his XR452 back in 1996-97?? There are many expert/pro riders that are amazed at how well they do on an XR400R on tracks. And they don't even like the XR400. Amazing... So with some suspension mods, HRC power-up Kit, and some frame gussets, the XR400R can be a great motorcrosser. Mine was a great desert bike!
