toesnose, First gear, no prob. 1st to 2nd up shift, yep, there too. Second, a little more work, but yeah.
If you don't have experiance with wheelies or a dirt bike background and the front end comes up on ya, don't panic. Use the rear brake and ROLL off the throttle to stop the front from rising, no throttle chops to get it back on the ground. Don't try to stop, forward motion is your friend. Keep the bike as upright as possible and your feet on the pegs and if the bars wag when touching down, don't fight 'em, they'll smooth out quickly.
PS The down side is a crash...we're repairing the RC51 from when it was lent to a friend, and a good rider who grabbed an unexpected 50 extra HP. A 20 MPH looping crash is at the $2500 mark, and we're not through.
