First launched in 1987, the GPZ500S was Kawasaki's attempt at a modern, lightweight sportsbike. Its parallel twin engine owes much to the GPZ900R of 1984: in many ways, it resembles half a GPZ900R engine. The chassis is dated, but is still capable of being hussled down a fast back road or round a track. The suspension is too soft to offer truly sporting performance, but the brakes work well if kept in good order, and the relaxed steering geometry means predictable handling. In 1994, the GPZ500 received a facelift. New bodywork gave a more up-to-date appearance, while 43cm (17in) wheels allowed modern rubber to be fitted. Wider 37mm (1.5in) front forks stiffened the chassis.
