Did ATVA change Pro Production to 450cc?

I heard this on another forum. Havent seen anything about it on here though. :confused:

[bansheerider_13]

the production classes have always been 450 its the other classes that were 440 and they still are

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:

if ur think its because of the yfz its only a 440 yamaha is retarded so they call it a 450

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)
