The 1927 BSA B, also known as the BSA "Round Tank", had, at its heart, an air-cooled, four-stroke, 249cc, single cylinder lump paired to a two-speed manual transmission and could reach a maximum power output of 2.5 horsepower at 3000 rpm.
The most defining feature for this machine would be the cylindrical shaped fuel tank, hence the nickname, but it also comes with a single spring girder fork, a sprung single saddle, a hard-tail rear suspension, a single exhaust system, wire-spoked wheels and a rear luggage rack.
