All of my experience has been on 4-strokes. Took our new (well, new to us) 2-stroke out this past Saturday. Shot myself straight up in the air when I gave it a little too much off of a relatively small jump.
I have the highest respect for experience riders. However, after riding that smoker this weekend, I have an even higher respect for those guys that raced those things in MX. I really have an understanding now of "powerband" and how you need to "stay on the pipe" to control the bike. Both of those terms were relatively unkowns to me as I have only ridden four strokes.
Anyway, enjoy my messup!
