I have heard a lot of good things about the Recluse clutch. I'd like to ride a bike with one someday but I don't think I'm ready to install one for myself.
I was on a motocross track with Roger and his KX and my YZ about 3 weeks ago. It was a private track, just the three of us. Even so I did not like it, not for me.
To me it looked more like an obstacle course than fun. I was always afraid of crashing, and the race bike I was riding mocked me for my cowardice.
Dmmcd, how does your 'R' perform as a trailbike?
