Designed in wartime, the Sunbeam inline twin was introduced in 1947. A luxury tourer inspired by the pre-war BMW, 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 more conventional S8 introduced in 1949. Never as popular as BSA's more performance orientated models, the gentlemanly S7 and S8 remained in production until 1957.
The current owner purchased this un-restored S7 in 2017, since when it has been fitted with a new carburettor, new seat, and new tyres/tubes. Last run in August 2019, the machine is offered with an old-style continuation logbook and a V5C document.
