OverviewEdit
BSA A28, A29, A30
The model description in the catalogue is very promising indeed: Its a machine that anyone can learn to ride in a few minutes, and ride with confidence, because it is so light, comfortable and easy to handle. The two stroke engine is easy to start and very economical to run. This machine is fully capable of doing long distance journeys at a good average speed and it is backed by the B.S.A. reputation for consistent reliability.
Introduced for the 1928 season, the A28 was BSA's first production two-stroke.
In terms of its specification, the little BSA was a cut above the (predominantly) Villiers-engined opposition, boasting unitary construction of the engine/two-speed transmission, a dry clutch and primary drive by gears. The engine/gearbox unit was carried in a bolted-up duplex frame and there were two brakes, both of which operated on the rear wheel. Priced at £28 10s, the A28 comfortably undercut BSA's cheapest four-stroke model, the 249cc B28 De Luxe, which cost a comparatively hefty £37 15s.
