WP conversion for me. Its a bit of a pain to be honest. I have 640 sm forks ( as they stiffer springs and higher damping setup as standard) and are shorter travel at 265mm , exc yokes and left fork bottom/brake mount. The yokes have too be post 2011 then the steerer is metric where it fits into the yoke. But still has a metric bearing.
you can then use the steerer from the tenere and make a top hat spacer too take up the space between the steerer and top yoke. Lots of homework but makes an incredible difference
