In a period review, Cycle World called Kawasaki’s KZ1300 “an incredible hulk”, saying “There are motorcycles with more speed, but not with the same combination of power, strength, comfort and handling…the sophistication is incredible, the size is enormous.” Displacement-wise, it was the biggest of the classic six-cylinder motors like the Benelli Sei and the Honda CBX. Like the competition, the KZ wasn’t a commercial success but collectors now appreciate the audacity of a bike that screamed excess from the weight to the price.
Built for 10 years, the 1,286cc engine produced a hefty 120 horsepower. Top speed was similarly significant with magazine tests showing that it was capable of hitting 140 mph. But the 710 pound wet weight meant it was thirsty, with a mpg rating of approximately 30. For more information, check out this ‘six-cylinder’ comparo from Motorcycle Classics.
This example is engine #: KZT30AE007740. The seller acquired it as a spare when he owned a KZ1300. At the time, he was told that it had covered approximately 17,000 miles. He recently sold the bike, so he is no longer in need of the motor.
