The later A1 Samurai kept the lightweight two-stroke twin layout of the early bikes, with rotary disc valves, oil injection and drum brakes. Kawasaki changed the ignition from contact points to capacitor discharge in 1969, which is the main difference from the 1966-68 bikes. The A1SS, with a crossover exhaust below the seat, belongs to the same family.
