After victory in the 1920 Junior TT, AJS's new overhead-valve 350 racer scored a memorable double the following year, Tom Sheard winning the Junior race, and Howard Davies the Senior - the first time such a feat had been achieved on a 350. The production version made its debut in November 1922, delighting clubmen everywhere with its 'racer on the road' performance. A right-first-time design destined to achieve countless successes in the hands of privateers, the overhead-valve 350 AJS - latterly known as the 'Big Port' - changed only in detail before being superseded by a much-revised M6 model for 1929. The latter's engine incorporated a number of improvements including enclosed rocker gear and dry-sump lubrication, while the valve/port sizes were reduced; despite that, the 'Big Port' sobriquet continued. At the same time the frame was redesigned to accommodate a saddle tank, and Webb forks replaced the earlier Druids.
The machine offered here incorporates a Model M6 engine and what is believed to be the (modified) frame and cycle parts of a Model M12 '250', while many of the minor components are from other sources.
A past participant in numerous parades and Vintage runs, the machine is described by the vendor as in running condition and nicely patinated, ready to take part in many more such events. Offered with a French Carte Grise.
