1933 Sunbeam 350cc Model 8
Registration no. RE 7744

Engine no. KK4125

Sunbeam introduced overhead-valve engines in the mid-1920s having established its not inconsiderable sporting credentials with sidevalve machines. The Wolverhampton concern missed the virtually wholesale switchover from flat-tank to saddle-tank frames for the 1928 season, and its saddle-tank models did not appear until September of that year. Changes to the OHV engine were confined mainly to its top-end: early flat-tankers featured a straight-ahead exhaust port, a peculiarity which necessitated the adoption of a bifurcated down-tube, then later in the 1920s the fashionable twin-port cylinder head became an option before Sunbeam standardised a single-port design in 1934. Pushrod enclosure had arrived by 1930 to be followed a couple of years later by partial enclosure of the rocker gear. Dropped in 1930 when a new overhead-valve 350 took its place in the range, the Model 8 was reintroduced for 1933. Effectively a junior version of the 500cc Model 9, the Model 8 was capable of a top speed of around 80mph in solo trim.

First registered on 28th March 1933, this twin-port Model 8 is presented in 'oily rag' condition. The Sunbeam was in the Stafford area between 1950 and 1960, belonging to a Mr Cloke of Rock Cottages, Sandon and then Mr Guy Luckman of Kineston Avenue, Stafford. Our vendor purchased it in November 1995. The previous keeper was Cyril Johnson of Great Bridgeford, Stafford. He appears to have been the owner since at least April 1978 according to the old-style V5 on file. The file also contains an old-style continuation logbook dating from 1954 and a current V5C. The frame number matches the HPI. The engine turns over.

Prospective purchasers should satisfy themselves with regard to this motorcycle's completeness, history, authenticity, originality and mechanical condition prior to bidding.
