The Dickies British Supersport Championship leads the support class line up and in 2018 will feature an incredible line up of riders representing the world's leading manufacturers.
Plus in 2018 a new racing category was introduced alongside the Dickies British Supersport Championship.
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 will now be formally accepted into the British Championship.
The new category, designated British GP2 will allow 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 Stock 600.
The 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.
