Superbike is the top race class in the NZSBK Championship. Open to all manufacturers of motorcycles sold in New Zealand, this class gives distributors of sports production machinery the opportunity to showcase their machines in a competitive environment.

The appearance from both front and rear and the side profile of Superbike motorcycles must conform to the homologated shape (as produced by the manufacturer). Some modifications to machine set-up are allowed, with engine capacity of:

• 800-1300cc, 4-stroke, 2-3 cylinders max
• 750-1000cc, 4-stroke, 4 cylinders max
