The KH 400 as listed for 1978 and 1979, a 400 cc three-cylinder two-stroke with a single front disc and kick start. The spec table matches the earlier listings, and the performance notes come from a 1977 road test rather than from these years. The reviewer found it quick in a straight line and strong on power delivery, but less precise in handling and with a limited range of about 100 miles.
