In October 1970, the first example of a lightweight 'specialty K-car' - the 'Z' went on the market. The Z utilizes the same floor-pan and mechanics as the N360, Honda's first K-car, but with a sporty body design, incorporating a slanted front window, longer front nose, and a unique rear window. It shares the same engine as the NIII360 (which was a minor update model of the N360): a 360cc air-cooled SOHC inline-2, of which there were 31 HP single carburetor and 36 HP twin carburetor models.
