Lot 238 - 1946 Sunbeam 7 Mk. I
|Estimate||£2,500 - £4,500|
|Result||Sold - £3,920|
The Sunbeam S7 and S8 were British motorcycles designed by Erling Poppe based on the BMW R75 designs that were acquired by BSA together with the full rights to the Sunbeam brand at the end of World War II. Built in Redditch, the engine layout was an unusual in-line 500cc twin which drove a shaft drive to the rear wheel. The inline engine made this technologically feasible as horizontally opposed twin engines on BMW motorcycles had already used shaft drives. The early S7 was expensive and over engineered which is why it is now the most sought-after and commands a premium over the S7 De Luxe and the S8 which were produced with fewer features to reduce costs while retaining many of the innovative parts of the early Sunbeam and updating some ideas.
Some early models of the original S7 were produced in black but most in the now familiar Mist Green. Erling Poppe's design was originally based on a captured BMW R75 but Sunbeam did not want the S series to look too 'German', so an in-line OHC, parallel twin was designed instead of a flat twin 'across the frame'.
This Sunbeam Mk. I is a restoration project and, as such, we know very little about the motorcycle or its history. It is believed that with all the accompanying parts, this would qualify as a fantastic project and could be fully restored to a sought after bike with only 2,000 produced between 1946 and 1948.
