New for 2022, the Sterling is a steamlined sports touring sidecar, inspired by the elegant roadster motor cars of the 1930s.

The sleek body shell is manufactured from fibreglass, with a polished gelcoat finish in black. Other colour options are available on request and we also offer a colour-match paint service.

It sits on a specially-designed platform chassis, with independent hydraulic suspension, and a 16″ spoked wheel, (with a choice of black or chrome rims).

The minimalist mudguard hugs the tyre and comes with tail light and indicator fitted as standard, complete with wiring.

There is plenty of legroom inside, with and upholstered bench seat, and aluminium-trimmed Lexan screen to protect the passenger from wind and rain.

Tilt the seat forward to reveal a generous size luggage bay, so you can travel free of clutter.

Pictured here fitted to a BMW R 18, with many extras, including BMW spotlights and bespoke badge.
