You can run any size CC quad in pro production.

Chad Duvall runs pro prod. on a 500ex....:)

You have to keep stock cases and frame that's all...:ermm:

In the GNC's the limit is 450cc's for the Production classes and 440 for the rest except for open.

Ah i see. I know the new 450 is actually a 440. Im not too sharp on the classes seeing as i have never raced. (damn west coast)
