1966 BSA 500cc A50 Royal Star
Registration no. GOY 62D
Frame no. A50R 14720
Engine no. A50R 14720

Following Triumph's lead, BSA turned to unitary construction for its range of twins as the 1960s dawned, launching the all-new 500cc A50 and 650cc A65 'Star' models in January 1962. The basic architecture of the preceding A7/A10 models was retained, so the new engine remained an air-cooled parallel twin with 360-degree crankshaft and single camshaft mounted at the rear of the cylinder block. The cycle parts remained much as before. When the range was revised for 1965, the touring twins were renamed 'Royal Star' (A50) and 'Thunderbolt' (A65) respectively and, together with the 'Lightning' and 'Spitfire' sports roadsters, received the superior two-way damped front fork from the off-road Victor model. The Siamesed exhaust systems used previously were dropped. Acquired by the vendor in November 1987, this particular A50 has been in dry storage for several years and will require re-commissioning before further use. Sold strictly as viewed, the machine comes with an old-style V5 registration document and is offered without reserve.
