Not sure, but I would 'think' that would lower everyone's power including the people that are in fact legal. The tracks (HPR and Pueblo) are safe enough to run 220hp superbikes on them, so safety isnt the issue like Nascar at some tracks. But how would you monitor some of the cheating? If you cant monitor it cheaply, you cant try and regulate it.

I 'think' this is why it was easier in Moto2 to have spec motors, teams lease the motors and the motors are sealed which makes it easier to control/monitor engine modifications, but electronics are open. In BSB they are going to spec ECU's to try and control the class more (as well as tighter engine rules) and I guess we will see how that works.

If OEM's dont believe in a club to control their classes, they are less inclined to support that club with either contingency (yes it has almost all disappeared) or rider support.
