British Supersport Championship
British Supersport Championship is a support series to the British Superbike Championship for engine capacities smaller than Superbike. British Supersport runs one or two rounds per weekend at each BSB event. The BSS Championship is seen as a stepping stone for the younger talent to progress to the British Superbike Championship or to World level classes. Riders such as: Tom Sykes, Cal Crutchlow, Sam Lowes, Alex Lowes, Jonathan Rea Leon Camier and Rory Skinner; all raced in this championship during their early careers.
From 2018, a new British GP2 class was introduced to be run within existing Supersport races. Devised by MSVR, it is based on Moto2 Honda-engined machines.
From 2023 season onwards, new engine regulations are in force allowing larger engines to be used, dependent on the number of cylinders, from manufacturers such as Ducati and MV.
During round 1 of the 2025 season at Oulton Park on 5 May, 11 riders were involved in a "chain reaction" crash at the first corner. Two riders, 21-year-old Owen Jenner from England and 29-year-old Shane Richardson from New Zealand died of their injuries the same day, and a third, 47-year-old Tom Tunstall suffered serious injuries.
