The Kawasaki Z750, also called Z2, is a four cylinder motorcycle made by Kawasaki as part of their Z series, introduced in 1973 for the Japanese market. Regulations at the time mandated a maximum capacity of 750 cc (46 cu in), so the 900 cc (55 cu in) Kawasaki Z1 could not be sold in Japan.[1]

Visually the Z2 is similar to the Kawasaki Z1, with the main difference being the smaller displacement. The new 746 cc engine was built with newly designed pistons and crankshaft parts to give it a feel similar to the Z1's 900 cc four cylinder engine. The engine had a maximum output of 69ps at 9,000 rpm and could propel the Z2 to a maximum speed of 170 km/h.[citation needed]

Production of the Z2 began in March 1973 and the bike recorded sales that were 10% higher than its nearest 750 cc competitor973 and the bike recorded sales that were 10% higher than its nearest 750 cc competitor
