1973 Kawasaki S-2

A legendary 1973 Kawasaki S-2 ridden by a 1954 Healy DS-1 (a legend in his own mind!).

The 1973 Kawasaki S2 Mach II is a legendary, mid-sized 346cc air-cooled, two-stroke inline three-cylinder motorcycle celebrated for its snappy acceleration and iconic "triple" exhaust wail. Often called the little brother to Kawasaki’s terrifying 750cc "Widowmaker" H2 Mach IV, the 350 S2 packed an aggressive power-to-weight punch that made it a dominant force on both suburban streets and club racing circuits.

 

The 346cc, 2-stroke, piston-port, inline-3 produced 44 hp @ 8,000 rpm. It had a 5-speed manual transmission and a dry weight of 330 lbs. Top Speed~106 mph, with 0–60 mph coming in 5.4 seconds (provided the oil injectors didn't foul the plugs).

 

The S2 Mach II was a brief flame, produced only from 1972 to 1974 before being replaced by the less aggressive, emission-choked 400cc S3.
