Superbikes competing in this class are race machines developed from production road-going, litre-class sportsbikes of between 1000-1200cc. Stripped of lights and road-bodywork, the machines are lightened significantly and fitted with up-rated suspension, chassis, engine parts and full race exhaust systems. The result is a machine that produces in excess of 200bhp and is capable of speeds of 200mph. In 2016 Bruce Anstey was clocked through the speed trap at 209.8mph, the current record.
The NW200 features two Superbike races on race day and these races are seen by the fans as the main events. Past winners have included some of the road racing greats, such as Joey & Robert Dunlop, Phillip McCallen, Carl Fogarty and of course the likes of Michael Rutter and John McGuinness.
