1927 B27 DE LUXE



First seen in 1924 and built by the Birmingham Small Arms Company Limited (BSA), these bikes were top-selling models for BSA during the 1920s.

The light weight and versatile original Model B, or ‘Round Tank’, was used by most tradesman whose job required cheap personal transport.

The gearbox had only two speeds and both brakes operated on the rear wheel only which helped give learners confidence when they rode the bikes.

All bikes were built with BSA's reliable 250cc side valve engine.

Advanced features for a lightweight included all-chain drive and pumped lubrication, though the traditional sight feed and auxiliary hand pump were retained.

In 1927 a wedge-shaped tank replaced the round tank on the ‘De Luxe’ version.


A beautiful example of an original Veteran BSA lightweight motor bike.

This bike retains its original 2.49 HP engine, 2 speed gearbox, tool compartment and gorgeous leather saddle bags.

Standard B27s prior to 1926 had round tanks whereas this De Luxe model sports the more fashionable tapered tank (a work of art in itself) and a more comfortable saddle.

These bikes are reliable, easy to maintain and economical (120 mpg).

This bike has been regularly rallied and shows a tasteful amount of patina.

It comes with a spare engine.
