Quattro Group British Supersport and GP2 Championship

The Quattro Group British Supersport Championship leads the support class line up and this season will again feature an incredible line up of riders representing the world's leading manufacturers.

The middleweight class for typically 600cc capacity machines has regularly provided some of the fiercest, closest racing ever seen and for nearly three decades has been exclusively restricted to production-based models.

Following two years of evaluation, prototype machines of a similar specification to those seen at World and European Championship level in the Moto2 category were formally accepted into the British Championship for the first time in 2018 and will continue in 2021.

The category, designated British GP2 allows for current Honda-powered Moto2 machinery that has been used in World or European Championship competition as well as new, independent constructor projects utilising any 600cc four cylinder or 675cc three cylinder engines to a technical specification very similar to Junior Superstock.

The Quattro Group British Supersport and British GP2 categories race side by side and be separately classified – together with a background classification to see who is the best of the best.
