Like the WSA the CSRA has adopted the 600cc rule for the open class sleds. However to shake things up a little they have now allowed the use of 4 strokes into the class. Maximum cc is 1050cc's. Read on:
2005-2006 Snowcross Season
(Monday, August 08, 2005)
The CSRA has announced a few changes for the upcoming snowcross season including additional race classes.

Snow Hawk (18 plus) 0-600cc stock Class:

All Open Classes:
Effective immediately, all Open racing classes will be limited to 600cc 2-stroke engines and limited to 1050cc 4-stroke engines.
There is a 1.75 ratio in effect for 4/stroke snowmobiles (Example: 600cc x 1.75 = 1050cc 4/stroke). The new Yamaha snowmobiles under 1050cc will be permitted to compete in the Trail Sport 600 and Sport 600 Stock classes, as well as, the Open classes.
Qualifying Format- All classes – Moto’s & Finals:
This race season all racers will qualify to finals with the moto system
Yamaha has been trying to make us forget about the so called cc classes and instead focus on h.p. of each sled. They consider the Vector in the 120 horsepower class for example. The way I see it a 1050 cc 4 stroker falls into the same catagory as the Fusion 900. Around 150 ponies. At least Yamaha would have us believe the new Apex is around 150 ponies so I assume a race prepped 4 stroker ( change the cams, bump the compression, different exaust etc ) should be right up there with what the 800 open mods were at. Close to 180 or so ponies. This being the open class the manfactures/race teams are really going to have to step up if the want a 600cc 2 stroker to compete with a 1050cc 4 Stroker. I don't think this will be a big issue on a short technical track but on a track thats a little longer I'd say look out. One last thought here is if the WSA adopts the same rulz and with Morgans contract ready to expire at the end of this season with Doo could a jump to Yammy be far off. Sure he is getting old but he is a proven winner and lets not forget he rides a Yamaha in MX.
