AJS was founded in 1909 by the Stevens brothers, although the family was involved with the production of motorcycles before the turn of the century. The first engines of 125cc were used by other companies. In 1905, Stevens built a bike with a JAP V-twin, with leading-link front forks and a swinging fork at the rear. They had also been producing frames. Design improvements for 1921 and revised engines brought many sporting successes. Most remarkable of those were at the Island TT, where they took an impressive first, second, third, fourth and sixth, followed by a resounding win (by a two-minute lead) in the Senior TT, two days later. In 1927, it had become clear that push-rod overhead-valve designs were becoming dated in racing, so AJS introduced two new chain-driven overhead-camshaft racing models, the 349cc K7 and the 498cc K10. Jimmy Simpson rode a 350 to third place in the Junior TT and won races in Europe, but in 1928 AJS used the overhead-valve engine in the TT. In 1929 there were again two machines with an overhead cam, this time the 349cc M7 and the 498cc M10.
This very handsome, matching-numbers 1928 K10 is probably one of the rarest AJSs available today. The vendor, who has restored many AJSs of the years, purchased it stripped-down and requiring restoration, and duly rebuilt it over four years to its present outstanding condition. It has won many awards at major shows around Britain since completion. During the overhaul, it had a new set of flywheels, con-rod, piston, rings and all new bearings throughout, along with a new set of close-ratio gears. The paint finish is to an excellent standard and the nickel is of a very good quality. The K10 has not been used much since completion and will still need some running-in. It is accompanied by a current V5C and a photograph showing it pre-rebuild.
