The ultimate development of the 1947 Rex McCandless Featherbed Frame Design.
This model features the Slimline variation of the design.
The 650SS was a Norton motorcycle made by between 1962 and 1967 at Norton’s Bracebridge Street works in Birmingham. Developed from the Norton Dominator, the Featherbed frame was altered so that the top rails were closer together to create what became known as the ‘slimline featherbed’. A 650cc twin carburettor engine was installed which was capable of 110–115 mph (180–185 km/h).
The ‘SS’ stood for Super Sports and the 600cc models were discontinued to concentrate on production of the 650SS, which quickly earned a reputation as the best of the Dommies.
Fitted as standard with twin Amal Monobloc carburettors with the intakes angled downwards. Twin exhausts replaced the 99SS two-into-one and the headlight nacelle was replaced with a modernised speedometer and tachometer. The 650SS was finished in a black frame with silver fuel tank and optional chrome fenders.
In February 1962 Motor Cycling magazine achieved a best one-way speed of 119.5mph at MIRA with a 650SS, more than 10mph faster than the rival Triumph Bonneville tested the previous summer.
