not preventing them from entering - as they can still enter 600 - and compete with like powered bikes...
FXRRC has a break point at 2003 in effect doing the same thing..

I may be biased, but having my zx6 eligble next year does not make a whole lot of sense in the interest/ intent of the class. A current spec bike competing with the older machinery...30hp difference makes a big difference, especially in the right hands..

TBH, if I was building an 07 bike just to enter 600 CS, I would need to consider why wasnt I entering 600 as that is the class of bike?

I think its great for this to get out there - it gives a competitive class for the 95-03 bikes to play!

and the injected bikes are still competitive in the 600 class...
