Combining the 350cc Model 8's bottom-end and 90mm-stroke crankshaft with a 59mm-bore cylinder barrel resulted in a new 'Longstroke' 250 for 1933 - the Model 14. For the 1935 season the latter was superseded by an all-new 'high camshaft' design, the Model 16, only to return in 1936 in improved form following the 16's disappointing failure. To reduce costs, Burman gearboxes were fitted to many models, the revamped '14' included, but Sunbeam had built its reputation on superlative quality of construction and finish and was unable to drop its standards sufficiently to match its rivals for price. By this time the writing was on the wall for the Wolverhampton concern and in 1937 new owners Associated Motor Cycles took over. Production shifted to Plumstead where the existing range, including the Model 14, continued for a couple of years before new models were phased in. One of the last Sunbeam motorcycles to be built at the Sunbeamland factory in Wolverhampton, this Model 14 was fitted many years ago with a 347cc Model 8 engine dating from 1938. (It should be noted that the V5C registration document still records the original engine number and 250cc capacity). We are advised that the magneto has been overhauled and the fuel tank sealed, and that the machine benefits from a new carburettor float chamber and new clutch plates. Described as in generally good condition, it is offered with current road fund licence, MoT to November 2010 and Swansea V5C.
