That's the bike, Spud! Mine was blue.
I'm leaning towards favoring a tiered system myself.
The problem with that though is:
-Falling off a 200cc bike at 65 feels the same as falling off a high performance bike at 65.
-In America I believe people have a right to do stupid things that can get themselves killed as long as it does not directly harm others. Consider flying, rock or mountain climbing, or consuming mass quantities of cheeseburgers.
-A high performance bike only goes as fast as you twist the throttle. It is capable of simulating the performance of a 200.
