1928 Sunbeam 347cc 'Model 8'
Registration no. DC 8085
Frame no. C1207
Engine no. K1254
Wolverhampton based Sunbeam had begun experimenting with overhead valves on their factory racers in the early 1920s and these duly appeared on production models in 1924. The new 500 roadster was known as the Model 9 while its competition counterpart, which could top 90mph, was accordingly designated the Model 90. The road and race 350s were typed Model 8 and Model 80 respectively. The Wolverhampton concern missed the industry's virtually wholesale switchover from flat-tank to saddle-tank frames for the 1928 season, and saddle-tank models did not appear until September of that year. Changes to the overhead-valve engine were confined mainly to its top-end. The early flat-tankers featured a straight-ahead exhaust port, a peculiarity which necessitated the adoption of a bifurcated down-tube. Later on in the 1920s Sunbeam followed the then fashionable trend to twin-port 'heads before reverting to a single-port design. 'DC 8085' was restored in the 1970s and last MoT'd and ridden on the road in 1972. Kept in storage since then, it will require re-commissioning and the customary safety checks before further use. Offered with V5C registration document.
- The engine number is K1059. Bonhams consultant and Sunbeam specialist Bob Cordon Champ has inspected the machine and believes the frame is likely to be the original.
