1972 Kawasaki H2 750 Mach IV

So if the 500 H1 was  Kawasaki’s original “widowmaker”, what do you get when you stuff a bigger, badder motor into the same bike?  The H2 750 Mach IV was an evolution of the earlier three-cylinder machine, and by “evolution”, I mean “they stuffed a 50% larger motor into the existing bike without really fixing what was wrong with it in the first place.”

Kawasaki’s line of 2-stroke triples are all well known to punch well above their weight and have a deserved reputation as “widowmakers”: the motors combine high specific outputs with a lightswitch powerband, primitive suspension, and marginal brakes, all packaged into a frame with the approximate stiffness of al dente pasta.

So many ways to get yourself into trouble: these bikes were cheap speed, in the true American musclecar idiom.  Except a Chevelle doesn’t fall over if you get it wrong…

Luckily, most of the people lusting after these at this point are, ahem, more mature than the folks buying them when they were new.  Those people are all long dead of course, so the rising prices of these machines must be based on their fearsome reputation, not actual, dewey-eyed nostalgia.

From the original eBay listing: 1972 Kawasaki H2 750 for Sale

This 1st model year 1972 Kawasaki 750 2-stroke triple underwent a painstaking, meticulous 12-year restoration. It was finished October, 2012 and has been ridden 107 miles since then.

Several aspects of this bike were not done with 100% originality in mind. It is plated/polished in areas the Kawasaki factory did not know existed. This is an early production H2 which means it has slightly different cylinders/porting from the factory which translates to a more exciting powerband. However, it is not early enough to have a plastic headlight nacelle. Currently it has a period correct Hella H4 headlight upgrade although the stock light is included.

The 2nd disc brake up front is in fact a dealer sourced kit from way back in the day. The extra caliper, 2nd disc, brake lines, hardware, splitter, etc., are all the pieces one would have gotten from the dealer. The master cylinder is the 5/8″ variant that came with the kit.

These are sort of insane bikes, although I guess maybe the second brake disc on this example makes it slightly less so…  Or maybe it just makes the forks and frame more likely to bend when you grab a big handful of whoa trying to scrub speed before a corner…

I’m not a huge fan of the looks, but these triples sound evil and should make for a thrilling ride: note that the seller refers to the “more exciting powerband” of the early H2’s.  Not exactly sure how that compares to later machines, but I do know that sharks attacks are considered by some to be pretty “exciting” as well.

Hopefully this H2 is more fun than a shark attack.
