In an effort to simplify and help racers get the maximum amount of time on the track the USCC has announced changes to its' 2009-2010 season's rules.

These rule changes include all riders being required to have a SNELL 2005 certified helmet.

Juniors 14-17 can run the 85 horse-power class snowmobiles. Juniors 10-13 can run 380cc max fans or the 85-hp class sleds with gear reduction ratios.

Sport 600 and Sport Improved classes will replace the amateur classes. An Expert 85 class will be added, and the Improved 85 class will not add internal motor mods. This class will only allow bolt on mods.

Snowmobiles eligible for 85-hp classes are limited to 2007and newer Arctic Cat non-power valve 500cc, Yamaha Phazer and all fan-cooled sleds.

A trail class has been added. Eligible snowmobiles will include liquid-cooled sleds 500cc and smaller and fan-cooled sleds 600cc and smaller.

Any year sled can run. This class is where you can run 440s and will be another option for Fan-cooled sleds to get more track time.
