The A50 Royal Star
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 and a two-pipe exhaust system, the Siamesed exhaust used previously having been dropped.
This numbers matching BSA Royal Star was purchased by the vendor seven years ago from sunny, dry Texas. Finished in rich dark blue paint with BSA's classic mirrored tank and a black saddle, it was restored to a nice standard prior to the current owner's acquisition of the machine. A smart looking bike with classic British café racer looks, it is nicely presented today correct details and minimal adornment—just a single rear-view mirror and speedometer. Zip on the leathers and find a windy road.
