British Supersport Championship

British Supersport Championship is a support series to the British Superbike Championship (BSB) 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 and Leon Camier 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.
