SQUIRE SIDECARS

Founded in 1973, Squire quickly gained a reputation for innovative sports sidecars, ideal for the new generation of Japanese superbikes. By the 1980s Squire was producing hundreds of sidecars for the importers of budget Jawa and MZ motorcycles, creating economies of scale that made sidecars affordable for more riders.

Squire merged with Watsonian in 1988, relocating to the current factory in the North Cotswolds. By the time Watsonian celebrated its centenary in 2012, Squire’s range of sidecars was looking dated and much of the tooling required to make them was obsolete, so it was decided to pause production and focus on Watsonian’s classic designs, for which demand was growing.

Fast forward 12 years and the development team at Watsonian were looking to build a simple sidecar outfit that would be suitable and affordable for motorcyclists to get their first taste of life on three wheels.

They simplified the body shell used for the popular GP Manx sidecar and mounted it on a Platform Chassis, with rubber torsion suspension, as used on previous Squire models. 

Designed initially for the Benelli Imperiale 400 and sold as a complete package, the Squire SB1 was launched at Motorcycle Live in 2024.

The Squire SB1 proved very popular, however the Imperiale 400 was withdrawn from the Benelli range in 2025 and Watsonian looked for an alternative motorcycle to power the outfit.

Following intensive development work, the new BSA Bantam 30 was chosen and the updated Squire SB1 was launched in April 2026.
