This 1972 Norton Combat underwent a complete mechanical and cosmetic restoration at the shop.
The Combat engine was introduced into the Commando line up in 1972. It featured higher compression, hi lift cam, larger carburetors, and lower gearing.
The Combat engine had a habit of blowing up. Most of it was due to main bearing failure caused by the old-style crankshaft that flexed and the new-style case that was extra stiff. As the crankshaft flexed at high rpms It put stress on the main bearings causing failure.
Today, with the use of Superblend bearings and other improved modern parts, you can build a Combat spec engine that gives added performance with much improved reliability.
