Peter is often asked the question, "What is the difference
between the new Moto GP four strokes, the old 500's and the Superbikes?"
The main difference between the Moto GP class is not capacity it
is that Superbikes must be based on a road bike. i.e. you can, at least in
theory, purchase the 1000cc V twin from which Colin Edwards' race bike is
derived, the same for the Bayliss Ducati etc.
Up to now the Superbike class has been for 1000cc twins and 750cc fours.
From next year the fours will also be 1000cc.
The 500cc bikes and now the Moto GP bikes, both four stroke (up to 990cc) and
two strokes (still up to 500cc), have never needed to be related to any road
bike. Indeed the Moto GP rules specifically state that they should be prototypes
to differentiate them from Superbikes.
In effect the Moto GP bikes are more powerful and lighter than Superbikes.
