MotoGP and Superbike are the top level racing and production classes.Classic Racing is where participants race heavily customized bikes from an earlier era - usually pre mid '70s bikes.

Supermoto is a crossover motorcycle racing between road racing and motocross. The motorcycles are primarily motocross types with road racing tires. The racetrack is also mixed between road and dirt courses, mostly handcrafted.
