hi Simon, mate the forks are the same diameter as the XTX (43mm). I really dont think these will be any better than the standard forks on road as a motard but maybe ok for more bumpy riding on the dirt. This swap may be better for the XTR rather than the XTX... in my opinion.

it's all I had to work with at the time and at $250 were cheaper than buying new fork tubes to replace the bent ones I had on the original forks...
