Sunbeam S8

The Sunbeam S8 was based on a BMW design acquired by Sunbeam Motorcycle’s post-war owners, BSA. Erling Poppe modified much of the design to suit the British firm's manufacturing base, including changing the BMW’s boxer layout to a vertical twin to make it look “less German”.

Good for about 85mph, teething problems with vibration were soon resolved - but the machines were always expensive to build and never enjoyed the commercial success they deserved.

Dating from 1951, VMU 994 was originally fitted with a sidecar, however dropped a valve in 1964 and was put aside. Dry stored for many years it was eventually gifted to the Museum who passed it on to its current owner who restored it as a ‘solo’.

The vendor informs us that it is a particularly original example, including the ‘tinware’ and that is has been “nut-and-bolt restored" with new bearings, cables and wiring etc. to a very high standard. New EWC wheels with new tyres were fitted with heavy duty spokes; the engine was rebuilt with new ‘Stewart’ high-compression pistons, whilst a new Amal carburettor and correct ‘solo’ ratio worm and wheel were fitted to its shaft-drive. The frame and small parts were powder-coated and everything rechromed as it should be. Finally the engine and gearbox were polished to a fine finish.

Running and riding very well, the vendor reports that it "pulls like a train” and has been a popular exhibit at the Museum since completion.

This really is a lovely example and would grace any collection thanks to its presentation and the thoroughness of its restoration.
