I currently ride a 2012 WR450 and XR650L dual sport. I really like these little WRR's but, am I going to be disappointed coming from big bores. I will mostly use it for light trail riding up in Big Bear California. How do these W RRs compared to a WRF? Some of you guys know how hard it is to plate dual sport here in California. So easy fix would be to pick up a WRR and just go have fun. I will say that my XR650 is a pig on trails and I'm a little bit tired of it. Once you do the normal mods how do these bikes run? Are they as revy as the off-road only version? Do most of you guys get rid of the exhaust valve? Thanks for your insight.
