1922 Rudge Multi

The 1922 Rudge Multi was a motorcycle ahead of its time, boasting a unique combination of a reliable 500cc F-Head engine and a revolutionary transmission system. Rudge-Whitworth's story began in the 1860s with Daniel Rudge's highly successful bicycle company, churning out an impressive 400 bicycles daily. As motorised vehicles gained momentum, they initially distributed Werner motorcycles from Paris. In 1909, Rudge-Whitworth embarked on the development of their own motorcycles, introducing the iconic F-head engine design characterized by an inlet over exhaust valve layout. This engine configuration, offered in 500cc and 750cc sizes, remained in use until 1924.

A standout feature of the Rudge Multi is its innovative Multi gearing system, an early form of Constantly Variable Transmission inspired by the Zenith Gradua-Gear. This system utilises two curved plates, controlled by a long handle, to adjust the leather drive belt's position on the pulley, thereby altering the gearing. Belt tension is maintained through a similar process applied to the rear drive rim.

Rudge Multis earned acclaim on the racing circuit, notably participating in the first Isle of Man Tourist Trophy on the Mountain Course in 1911. The Rudge Multi secured second place in 1913 and emerged victorious in the following year's event.
