The Force 21R Car 3P Standard ABC Rear Exhaust Engine (SG-Shaft) delivers competition-grade performance in a meticulously finished package. Precision casting, clean machining, smart anodising and crisp laser etching underline the quality, while the internals focus on efficient power delivery and durability for serious racing.
Built around a highly efficient 3-port two-stroke design, the 21R pairs strong top-end speed with tractable power.

The rear exhaust layout and SG-shaft specification give a familiar setup path for race-focused installations, while ABC construction supports longevity and reliable sealing.
