Property of a deceased's estate
1953 Sunbeam 489cc S7 Deluxe
Registration no. SRB 521
Frame no. S7 6647
Engine no. S8 10823

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 made 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 particular S7 comes with an old-style buff logbook showing that it was first registered on 5th January 1953 by Derbyshire CC and resided until 1962 in Chesterfield. From 1972, the Sunbeam would appear to have moved to Sheffield where it was acquired by the lady vendor's late husband in 1981. A current V5C is present also. Not run for some time, the machine will require careful recommissioning before returning to the road.
