Kawasaki GPZ1100

The Kawasaki GPZ1100 is a large motorcycle that Kawasaki built from 1981 to 1985, the first 1,100 cc machine the company released. Every version used a 1,089 cc engine and fuel injection, and the line was an attempt to serve a market segment that was changing quickly. The 1981 B1 combined a cradle frame with an engine derived from the Z1000J motor and a Bosch-derived electronic fuel injection system, and its claimed output was 108 horsepower, about 81 kilowatts. The 1982 B2 added a cockpit fairing and replaced the analog injection with closed-loop digital fuel injection. The 1983 ZX1100-A1 brought rear Unitrack suspension, anti-dive forks, a restyled look and a claimed 120 horsepower, and the 1984 A2 changed little before the model was discontinued as the lighter, water-cooled GPz900R took its sales. A different carburetted GPz of 1995 to 1997, designated ZX1100E, shares only the name.
