The Micro ROK and Mini ROK classes fulfill that age group, utilizing the popular 60cc Mini ROK engine (exhaust restrictor and spec gear for the Micro class).
The ROK GP engine is the flagship powerplant, utilized in the Senior ROK, Masters ROK, and Junior ROK. A 125cc ‘Touch and Go’ water-cooled engine is the backbone of the ROK engine platform, allowing racer to compete in all three classes with a single engine (Junior ROK requires an exhaust restrictor).
