Vintage Class & Arctic Cat 4 Stroke Rule Changes/Reminder

Just reminding Vintage class racers that the same fuel can rules that all other classes have also apply to them at the Red Lake I-500. The minimum requirements for helmets also apply the same to Vintage class racers the same as all others at ALL USCC Vintage class races. We had some confusion with this last year at the I-500 & many riders were scrambling to find a legal helmet. For the most up-to-date gas can rules, click here. For helmet requirements, see the USCC Racer Handbook.

Also, the Arctic Cat 1100 4-stroke (non turbo) is now approved by ISR for racing in 600cc stock classes.
