I've held onto the 650R for another year after briefly considering the 450X. Think I'll wait and see what the CRF600X will be all about. When it comes to blending power AND reliability there's simply no replacement for displacement! The 650R is light years ahead of the "L" and if you can get it dual sported and can still kick a pig over I would go with the "R". ......As far as the 450X it looks sweet at 250 lbs but I haven't had a chance to ride one yet.
