A pedal is mounted on a bracket 36 attached to a motorcycle by a backplate 29. In one embodiment the bracket and backplate are connected by a link 35 and two threaded components (fig 9), and their relative positions may be adjusted by selecting which splines to engage. Another embodiment has a bracket (9, fig 2) bolted to two holes selected from an array of holes in the backplate (6, fig 1). A brake master cylinder and a footrest (fig 13) can be attached to the bracket. The pedal may rotate on sealed ball bearings, and be made in one piece, or two parts (figs 3-5,11,12) connected by screws and with a positive engaging shaped portions, e.g. hexagonal. The components can be anodised aluminium alloy. A four start helix cut into an external diameter of the footrests improves the grip. |
