For AMC, BSA, Triumph and Villiers, with your choice of a one-inch ("MX") or three-inch ("trials") swingout. These are especially nice, as they fold-up flat against the engine, so they don't interfere with your leg while riding. The trials version provides clearance for rearset footrests or exhaust pipes. Burman gearbox and Triumph T100 options are available by special order only.
