Rickman Motorcycles

Rickman Motorcycles was a British, independent motorcycle chassis constructor established by brothers Derek and Don Rickman. The firm manufactured motorcycles from 1960 through to 1975.

History

Initially the frame designs were for scrambles, and then for road racing. Later, in 1966, road bikes were produced as well. The first street legal bike used a Triumph Bonneville engine. Rickman initially supplied frame kits, as none of the major British motorcycle manufacturers would sell engines to them. The frame kits were built for many engines, including Triumph twins, BSA singles and Matchless. In the mid-1960s, Rickman also produced road-racing frames for AJS 7R singles, and in the 1970s they began selling chassis kits for Japanese bikes like the Honda CB750 and Kawasaki Z1. The road bikes were the first to use disc brakes both front and rear (a joint project with Lockheed).

Other innovations included the use of large diameter telescopic forks (1-5/8" or 41.2mm) and oil carried in the frame tubes to help dissipate heat and save weight. An eight valve cylinder head conversion (700cc) for Triumph 650cc twins was developed in the late 1960s which considerably increased power output (up to 60 bhp or more depending on state of tune) and showed up some weaknesses in the Triumph crankcases and connecting rods. Chain adjustment was via eccentric discs rather than drawbolts to avoid misalignment.
