At the present time there is a 4-stroke class and the class size is 91-440 cc.
The 2-stroke class is 91-250cc and a 4-stroke of 91-440cc and also run in this class. This is also the same class size for the Pro class at the GNC races.
The production class is 91-450cc 4-stroke only.
All of this is the class sizes for this year.

 

thanks tprender!

 

LOL, "91-440cc". Who would race a 90 against a bunch of 440's ? what where the Atva dudes thinking when they made that rule? that is some funny stuff...(if it is true).

 

You have to have a starting point for a class. Before we had the lower limit at 91 it was legal for had someone tried to race with an engine of 90 cc. He was going out for the fun of it and was in the way. Just for your info also, All of the classes start with 91cc as there lower limt just in case you have not noticed.

 

Thats funny. The ATVA is not big. They dont have thousands of council members all taking a vote.

More like a couple of guys sitting around on there ***, drinking, and figured they would pass a new law. To make it look like there important.

 

not at all, bandit. the ATVA does have a good amount of members, and there are at least a hundred people voting in most states. Theres no grand conspiracy against Yamaha going on![img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-cool.gif[/img]
