The worlds best-selling race car
Ideal for novice to seasoned racing drivers alike, the Radical SR3 is the world's best selling race car for a reason. Launched with more power and precision, the latest XXR edition of the SR3 improves on the legendary SR3 formula to enable drivers to lap faster, harder and for longer.
The SR3 is available with either a 1340cc or 1500cc four-cylinder hand-built RPE racing engine to suit the driver's preference. Both are driven through a six-speed sequential gearbox with paddle shift and Quaife limited-slip differential, and are coupled with a new-generation racing exhaust system.
The SR3 XXR continues to offer AiM’s solid-state technology including a suite of data options and technology to help Radical drivers be the fastest on the race track. It also retains AiM’s popular Formula steering wheel technology, akin to those usually seen in high-level single-seater racing cars and Le Mans Prototypes.
