Superstock TT

The Superstock TT is a motorcycle road race that takes place during the Isle of Man TT festival. The event for production based motor-cycles racing on treaded road tyres is based on the FIM Superstock 1000 Championship specifications.

Engine capacity

The Production TT, racing for production based motor-cycles had been part of the Isle of Man TT Races since 1967 for 250cc, 500cc & 750cc classes replacing the Lightweight, Junior and Senior production motor-cycles of the Clubmans TT races (1947 – 1956). These production based machines raced until the 1976 Isle of Man TT when the classes were discontinued. The Production TT was reintroduced for the 1984 Isle of Man TT Races for 3 class classes, reduced to two classes on safety grounds for the 1990 races. For the 2005 Isle of Man TT the Superstock TT race replaced the previous 1000cc & 600cc Production TT classes that had been part of the Isle of Man TT race schedule since 1989.
