The easiest class to get into in any SSOI event, the upper limit of cylinder capacity is 75cc for 2 stroke machines and 150cc for 4 stroke machines. Grab a stock bike and off you go but it still leaves a bit of room for performance tuning.


The mid level class not recommended for beginner’s as these scoots generate 20hp upwards, the upper limit for capacity is 125cc for 2 stroke machines and 250cc for 4 stroke machines. stock bikes can be used but will require some fettling to make them competitive.


No holes barred race machines in this class, scooter performance machines with no limits.
