I like starting higher on the learning curve. I went riding dirt bikes with a friend last fall (my first time) and he let me loose on a Honda CR 250. Scared the $**t out of me the first time I cracked the throttle in 2nd! After riding that all day and burning $40 of 105 gas, I hopped on his CR 125 and it felt like I had to wait 5 minutes for the thing to get to the powerband.
