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.

Our vendor purchased this S7 from Verralls Ltd on 24th May 1995 (see copies of the invoice and purchase correspondence on file). The machine is presented in restored condition, currently displaying a total of 1,671 miles on the odometer (the engine turns over but without compression). The machine's previous UK registration 'VHW 545' is on the HPI database; however, the machine is marked as exported. Accordingly, prospective purchasers must satisfy themselves with regard to this motorcycle's registration status prior to bidding.

Following a period of inactivity, this motorcycle will require recommissioning and/or restoration to a greater or lesser extent before returning to the road and thus is sold strictly as viewed. Prospective purchasers should satisfy themselves with regard to this motorcycle's completeness, history, authenticity, originality and mechanical condition prior to bidding.
