Having emphatically established its performance credentials with the Mach III two-stroke triple, Kawasaki went on to ace the opposition with the awe-inspiring Z1. Launched in 1972, the big Z spawned a range of smaller fours, the first of which was the Z650. One of the most capable sports bikes of the 1970s, the Z650 - along with the contemporary Suzuki GS750 - helped dispel the myth that big Japanese bikes didn't handle, its sturdy duplex loop frame inspiring confidence in a manner quite unlike that of its predecessor's. Effectively a Z1 in miniature, the Z650's across-the-frame air-cooled motor produced 64bhp, an output good enough for a top speed of around 120mph. Complaints that the early model's single disc front/ drum rear brake set up was inadequate prompted the adoption of a triple disc system on subsequent models, together with alloy wheels, as seen on this 1978 model.
The presence of side reflectors and model designation 'KZ650' (on the side panels) would appear to suggest that this example has been imported from the USA. Unfortunately, there is no accompanying paperwork and the HPI has no record of a vehicle with the VIN number listed above. Fitted with after-market handlebars, Hagon shock absorbers, and a non-standard Neta exhaust, the machine is offered for restoration and sold strictly as viewed. The odometer reading is 22, 132 miles. Prospective purchasers must satisfy themselves regarding this motorcycle's condition, completeness, and authenticity prior to bidding.
Offered with key.
£400 - 800
