Lot 396

1950 Sunbeam 499cc S8
Registration no. SSY 315
Frame no. S8-2225
Engine no. S8 2882
A wartime design by Erling Poppe, the Sunbeam inline twin was introduced by BSA, owners of Sunbeam Cycles Limited, in 1947. A luxury tourer, it was of advanced specification with overhead-camshaft engine, shaft drive and plunger rear suspension. The clutch housing and four-speed gearbox bolted directly to the back of the engine, which was rubber-mounted in the duplex loop frame, an innovation that required a flexible joint in the exhaust system ahead of the silencer. The first S7 version was equipped with balloon tyres, a feature not carried over to the deliberately more conventional, and also lighter and cheaper S8, introduced in 1949. The front fork and 7" brake were now standard BSA components, and there were numerous other changes in the interests of rationalisation. Never as popular as BSA's more performance orientated models, the gentlemanly S7 and S8 remained in production until 1957.

This S8 was purchased by the current vendor in 2011 and has been used extensively on local rallies throughout the years and was running as recent as March 2025. Not much is known of its previous history other than it was restored by the previous vendor and is offered with a quantity of invoices from Stewart Engineering. Offered with the aforementioned invoices, old MoT's and a V5C.

All lots are sold 'as is/ where is' and Bidders must satisfy themselves as to the provenance, condition, age, completeness and originality prior to bidding. Visit the Bonhams Motorcycles website for all pertinent auction information.
