Kawasaki S2 Mach II

The Kawasaki S2 Mach II is a 350 cc motorcycle that Kawasaki introduced for the 1972 model year and discontinued at the end of the 1974 model year. It has a three-cylinder two-stroke engine of 346 cc and superseded the rotary disc valve twin-cylinder Kawasaki A7 Avenger. In displacement it sat between the 250 cc S1 Mach I and the 500 cc H1 Mach III in Kawasaki's family of air-cooled two-stroke triples, and the article on the S1 calls that smaller bike essentially the same motorcycle with less displacement. Sources disagree about the date: the article on the Kawasaki triples says the S2 350 was introduced in 1971 and the S1 250 followed in 1972, while the S2 article gives the 1972 model year. The source for this entry is short, so the description stops at what it states.
