About the Radical SR3
The Radical SR3 RS is the definitive club-level sports racer, bridging the gap between track-day specials and professional Le Mans prototypes. Powered by a high-revving Suzuki Hayabusa-derived engine developed by RPE, the 1.5-litre variant offers a significant performance boost over the base 1.3-litre model. Its lightweight spaceframe chassis and sophisticated aerodynamics generate up to 2.3g of lateral force, providing a pure, visceral driving experience. As the most popular model in Radical's history, it supports numerous one-make championships worldwide and remains a benchmark for lap-time-per-pound value.
