1981 Kawasaki Z1300

Kawasaki’s Z1300 – The Frame Game

Z1300CB-NET delves into the past to give you an idea of what came when in the classic world: this time – Kawasaki’s massive Z1300!

HUGE is not a big enough word for Kawasaki’s Z1300… even with us putting the caps-lock on!

It’s fair to say that Kawasaki’s amazing liquid-cooled six-cylinder monster was a beast, a behemoth, a leviathan of largess! And – while many said it was too big, daft, didn’t handle and (later) that it was an anachronism – it still managed to last in Kawasaki’s product range for around a decade and outlive its contemporaries.

The Z1300 came about, most probably, as a result of the superbike race begun by Honda in 1969 with its CB750. Kawasaki themselves would trump the Four with their 1972/73 Z1 of 903cc but as the 1970s progressed, so did cubic capacity… Honda released their 999cc GoldWing in 1974 and then the CBX1000 six-cylinder in 1978… which was ironically just a year before the Big K released their own six-cylinder effort, the Z1300…

Kawasaki Z1300Clearly both Jap sixes (let’s ignore the Benelli Sei yes?) were developed in an overlapping fashion, but while the CBX came and then (by 1982) went, the big Kawasaki lasted until 1989 in various guises. It was even made famous by the likes of stunt riders Arto Nyquist and Doug Domokos (go search for some brill old school footage of these two in action, on the six-cylinder Kawasaki…)

The bike itself was one heck of a machine. It weighed in at almost 300 kgs, it pumped out a not-too shabby 120bhp. The weight of the thing alone meant it would knacker rear shocks, fork seals, tyres wouldn’t go the distance and the first model had crank issues and yet we all loved it.

Want to be a spotter? Here’s the Z13 by the numbers…

Kawasaki ZN1300 ‘tourer’

This model was alongside the standard Z1300 from 1983. In a bid to take on Honda, Yamaha and Suzuki’s big-bore tourers (GoldWing, Venture and Cavalcade) this was most definitely a US-aimed version and therefore info is sketchy.
