Who designed Norton’s famous Featherbed motorcycle frame?

Rex McCandless designed Norton’s famous Featherbed motorcycle frame. The Northern Irish engineer developed the frame in the late 1940s, and Norton adopted it for its racing and production motorcycles.

The Featherbed was a twin-loop tubular-steel frame that improved handling by providing a stiff, well-balanced structure. Its reputation grew after Norton motorcycles using it performed strongly in racing, including the Isle of Man TT. Riders praised the frame’s stability and predictable handling, qualities that helped the design become a benchmark for later motorcycle chassis.

McCandless worked with Norton during a period when manufacturers were rapidly improving motorcycle suspension, frames, and engines. The frame was paired with Norton’s parallel-twin engines, including the Manx racing motorcycle’s power unit.

The nickname “Featherbed” refers to the frame’s famously comfortable and composed handling, not to a special material or an unusually soft physical construction.
