In the early 1960s, Kawasaki didn’t have much of a presence in the American motorcycle market — the brand’s bikes were little more than half-baked BSA clones. Upon the launch of the three-cylinder, two-stroke H1 Mach III, however, the Big K finally made a name for itself. With 60hp on-tap, a four-second 0-60mph time, and a top speed of 120, it was no time at all before it had earned its keep amongst even the most power-hungry of motorcycle enthusiasts.

Eager to keep the momentum going, Kawasaki proceeded to launch three more of such two-stroke triples: the 250cc S1 Mach I, the 350cc S2 Mach II, and the 750cc H2 Mach IV.

As the middling of the bunch, the S2 was largely overshadowed by its bigger, more powerful siblings. Nevertheless, Kawasaki continued to tweak the bike over the course of its production life. In 1974, the bike was renamed the S3 Mach II, at which time it also gained a bump in displacement (up to 400cc), rubber engine mounts, and a strengthened frame.

Power-wise, it was good for a claimed 42 horses — not mind-blowing, but more than enough to get you into trouble. That being said, the S3 was best-known for its svelte curb weight (under 350lbs) and impressive handling. Per a Cycle World review from 1974: “It can be flicked from side to side, power on, except in the first two gears. In that situation you have to ease the power on to keep the front wheel down. If it had a little more power, production racing the 400 could be lucrative.”

This example is VIN: S3F21058. The seller acquired it ten years ago from a friend with the intent of restoring it but he has decided that he won’t be able to get around to it.

The odometer shows 2,340 miles.

While this project is being offered in non-running condition, the engine is free and can be kicked through its cycles.

This S3 Mach II appears to be stock.
