In developing the Gen. 5 RPE engine, we wanted to optimize its potential as much as possible, while staying true to what makes the SR1 so user-friendly.”
Pinkerton continued: “Although it is an entry-level racer, the SR1 XXR offers an excellent package with unmatched performance for the money. SR1 and SR3 models currently make up the majority of grids in the 12 Radical Cup championships around the world. More than 200 SR1s have been sold to date.”

In recent years, we have seen our global racing offering flourish, with 12 official Radical championships now operating worldwide. Therefore, there was no better time than now to develop and improve the SR1, to give these aspiring racers the opportunity to race on bucket list circuits around the world. After the launch of SR3 XXR and SR10 XXR, it was only right to bring the SR1 under the XXR banner as well, since after all, it has proven to be the pillar of our company ethos – we make racers.”
