In common with other Japanese manufacturers, Kawasaki produced a number of small-capacity machines, which were popular enough at home, but failed to enthral the international market. In an attempt to crack the export market, they then tried reviving some of the old Meguro models, but again failed to make a dent. It was only when they came up with the 250cc Samurai that things began to change in their favour. Following with the 350cc Avenger and then the mercurial 500cc Mach III 'widow-maker', they had discovered the magical formula to captivate the international motorcyclist's heart; ultimate performance. With their range of triples, followed by the Z900 four, they continued the success, and eventually came up with the Ninja series of machines in 1983. The name was used on various machines of differing capacities from that time, and is still current today. The ZXR750 was a race-replica version of the 16-valve GPX750R, with higher performance, an E-box frame, and full fairing.
F597 MBU was purchased by the deceased owner in 1992 from Knott Mill Kawasaki (purchase invoice on file) and appears to have seen only limited use in his ownership. It displays an odometer reading of 16,635 miles, but has been standing for a number of years, and will therefore require re-commissioning before further use by a new owner. Documentation comprises an old type V5, together with a sales brochure, an owner's manual, and the aforementioned purchase invoice.
