The GP Manx has a shortened chassis, making it lighter and more compact than the Grand Prix – ideal for a sporting combination or smaller capacity motorcycles/scooters.

There’s plenty of legroom inside the cockpit of the GP Manx sidecar and, if you need to carry luggage, simply tilt the seat forward for access to the boot.

Like the other Grand Prix models, it has a fibreglass body that sits in a tubular steel perimeter frame, with a black powder coating to keep it looking good. Suspension is hydraulic and either 16” spoked or 10” cast aluminium wheels can be specified.

The vinyl-covered seat has a hinged back, which tilts forward to allow access to the luggage space behind.

A tonneau cover is included in the price and an all-weather hood is available as an optional extra.

Left or right side fitting
