It's all about the rush of gripping 200hp between your legs while waiting to drop the clutch lever and trying to get to turn # 1 first. It's all about going 140mph at full lean with your knee on the ground as you rear wheel is laying down a black stripe of rubber over a football field long. All the awhile your only 3 inches off the rear wheel of the rider in front of you trying to make the pass before the checkered flag. I doubt your experience ether of these on a 250
but like I said It's all about the rush and that can be had on any sized bike at the track.
