By 1977, all that was left of Kawasaki’s legendary line of triples were the KH250 and the KH400, the latter an evolution of the S3 Mach 2 – Kawi wanted to keep the names consistent with the KZ line. Unfortunately, the evolution was due to tightening emissions requirements, so the newer bike had less power – a disappointing end to a line of bikes that once included the Widowmaker.
That’s not to say the KH400 was a bad bike. Cycle World has the following to say in a period middleweight comparison: “But even with its little package of developments and refinements, the KH retains the kind of character that had it highly-placed in several of the performance-intensive test categories, and ranked down near to the bottom in the categories that emphasized comfort. It’s light (the lightest in the test at 378 pounds with a full tank), inexpensive ($1,239 suggested retail) and has the kind of power-to-weight ratio (12 Ibs/hp) that guarantees invigorating acceleration. It is also, in keeping with the larger-displacement Kawatriples that preceded it, a bit harsh in terms of finish, styling and myriad details which other factories handle more delicately. But crude or no, the KH is a genuinely fun motorcycle to be around— as long as you’re tuned into good handling and hot engines.”
This example (VIN: S3F38244) is claimed to be a complete restoration from the crank up, done by a former Kawasaki dealership owner who performed many personal restorations.
