Watsonian’s popular GP Manx sidecar is now available for Vespa GTS and GTV scooters
The design of the GP Manx dates back to the 1960s, although the octagonal nose was inspired by the Watsonian Sports sidecar of 1930 (so it was retro 50 years ago). Its fibreglass body offers 53 inches/1346 mm of leg room and the cockpit is 18 inches/457 mm wide, making it comfortable for passengers of most sizes. Access to the boot is achieved by tilting the seat forwards.
With a 300 cc engine delivering 22 HP and 22.3 Nm of torque, the Vespa GTS is well-suited to sidecar work, however finding suitable attachment points was challenging.
Watsonian developed a special chassis and sub-frame to attach the sidecar to scooter’s pressed steel frame, and fitted it with hydraulic suspension and a 12” Vespa front wheel for a balanced appearance and ride.
