H-1 Mach III 500, introduced in late 1968 with distributor.
In 1972, the 750 Mach IV (H2) was introduced and was essentially a scaled-up
version of the H1 500
In 1974, the 350 cc S-2 was expanded to a 400 cc S-3. In addition, the model
range was toned down in performance. The H-2 ceased production in 1975, and the
model line became the KH series in 1976. United States production stopped in
1976, while the 250 cc KH-250 and 400C KH-400 continued in Europe and elsewhere
until 1980.
The S-1 was popular for some time as a budget performance bike in England
because of its small size, and the fact that at this point in time it was legal
for learners to ride. The entire S series of motorcycles used breaker point
ignition, which was more reliable than the early CDI ignition and much cheaper
to repair or replace.
1969 H-1 500 cc white w/blue stripes, distributor CDI ignition, drum front brake,
"Mach III 500" badge on side cover and "electronic ignition"
decal on oil tank. Late 1969 saw the introduction of the Charcoal Grey model
1970 H-1 500 cc red w/white stripes on the fuel tank.
1971 H-1A 500 cc, style redesign without the Mach "III" badge, blue
with stylized stripes on the fuel tank.
1972 Entire line introduced, intended to be similar in style, with the "swooping"
racing stripes on the tank that distinguished the triples. S-1 250 cc, white w/green
stripes.also in red S-2 350 cc, red,also in white drum front brake H-1B 500 cc,
orange, disc front brake, CDI dropped for breaker points, and a front disc brake.
The H-1C is believed to have been made by
Kawasaki factory using up its leftover parts. It had CDI instead of the points
on an H1B and also a front drum brake as opposed to the disc on the earlier H1B.
Also a few cosmetic changes. H-2 750 cc, Blue or Gold - Gold versions were in
the early production run and went to the home market of Japan, Australia /
Southern Hemisphere and Europe but not to the U.S.A., front disc brake, CDI
ignition with one igniter unit per cylinder.

H2's CDI ignition and the styling that would be used on the later 1974 models.
H-2A 750 cc Purple/Gold.
1974 All models restyled with a new cleaner design that resembled the Kawasaki
Z-1, with an instrument "pod" rather than separate instruments. All
models revised for more civilized performance at the expense of raw power. S-1B
250 cc green, front drum brake. S-3 400 cc blue or red, disc front brake,
restyled cylinder head design for better cooling. H-1E 500 cc green or red. H-2B
