A little smoother on the bottom end and I thought it felt like it had a bit more on the top end. I was pulling wheelies getting onto the throttle on the straight. I never even got my temp gun out....the motor was barely warm after 5 minutes. For the price I just paid, this motor is an absolute no-brainer.
