For their Ultra-Lightweight class (50 cc) Grand Prix race bikes during the 1964, 1965 and 1966 race seasons, Honda re-introduced the 1920s format of cable-actuated caliper rim brakes with shoes/blocks directly acting on the aluminium rim-sides (alloy wheel rim), creating almost a 'consumable' item from the wheels, but dispensing with heavy conventional brake components, and allowing for experimentation with lightweight airflow-smoothing discs covering the wheel-hubs and centre-part of the spokes.[2]
