Re: 3 600cc classes next year

There are really only two classes for 600cc bikes next year, and they are quite different. They are:

"Supersport" - for mostly "stock" 600cc bikes on DOT race tires.

"Formula Extreme" - drops the 1000cc and 750cc fours, for heavily modified 600/4s and 750/Twins on slicks. (though I believe a Supersport legal 600 could probably be raced in Extreme, with a simple tire swap.)

The "Superstock" class is being modified to allow 1000cc inline 4s next year. I believe there is still some debate as to whether or not to stick with DOT race tires, or allow full slicks for safety's sake.
