The Norton Motorcycle Company, back in the late 1940s, developed a new motorcycle model and engine known as the Dominator. This was released to compete against their rivals Triumph Engineering who were the first to release a twin cylinder powered model known as the ‘Speed Twin’.

Our client, a Norton parts specialist, approached us to produce new drop forged and machined left-hand (LH) and right-hand (RH) inlet and exhaust rocker arms for the ‘twin’ engines that had became a staple of the Dominator model up until the late 1960s.

Relatively small batches of 100 pieces of each rocker type were produced, a speciality of W.H. Tildesley.

Our client who has invested in 4 sets of forging dies for left and right-hand inlet and exhaust rocker variants, has exclusive use.

If you require new forged components don't hesitate to get in touch with our team who will gladly assist you.
