I have had a couple calls in regards to the rules at mohawk and here are some answers as far as motors and weights: the only alowable motors are gsxr600=1220lbs....stock1000=1280lbs....spec1000=1300lbs...NO OPEN OR 1200cc MOTORS WILL BE PERMITED TO COMPETE !!!........All tires must be TUSA stamped tires and mandatory beadlock on the RR.....if you dont have a copy of the rules for mohawk i would suggest getting them before you make the trip...all rules are strictly enforced. if you have any questions you can contact Dean Pronovost or myself for any rule interpritation.thank you
