1972 Kawasaki Mach IV H2 Triple | ROOTS
MachSpeed: Kawasaki’s awe-inspiring 1972 Mach IV and the debunking of the Widowmaker myth.

The stories are out there, in print, online, and fresh from the mouths of folks without much of a clue. They chronicle lurid tales of wobbly, toss-you-off handling, uncontrollable third- and fourth-gear wheelies, 150-mph top speeds, and more. “This guy pulls alongside me,” you’re bound to hear. “Shifts into fourth and yanks a big stonkin’ wheelie!”

Today, the 1972 Kawasaki H2 looks purposeful and almost svelte. In its day, though, this was a feared machine, capable of a 12-second quarter mile and wholly up to separating the men from the boys.

THROWBACK - The ultimate collection would include all three of Kawasaki’s triples, the H1 500, the H2 750, and the S2 350. Kawasaki wowed enthusiasts with the powerful H2 but sold a lot of other three-cylinder versions into the 1970s.

Dan Mazzoncini’s 295-original-mile ’72 H2 is about as perfect as they get. First- and second-year bikes “are the wildest,” according to H2 owner and builder Jim Hobbs, “with changes to the ’74 and ’75, longer swingarms and porting tweaks, taming them a bit.”

With 71K miles on the clock, Mitch Feingersch’s H2 starts on the first kick, as Editor In Chief Marc Cook will attest. (See Cook's Corner here)![]()

And then there’s the infamous “widowmaker” moniker, routinely applied to the big Kaw… It’s all BS, really.

Yes, indeed, Kawasaki’s 1972 Mach IV—a.k.a. the H2—was shockingly quick for its day, faster than most street riders could wrap their heads around. It ran low 12s at the strip, quicker than any streetbike in history. It wheelied too easily in first gear, surged and shook like a wet dog at certain revs, got lousy fuel mileage (high teens when ridden hard), was loud, and smoked like a chimney. Yes, the very recipe for success.

THROWBACK - The ultimate collection would include all three of Kawasaki’s triples, the H1 500, the H2 750, and the S2 350. Kawasaki wowed enthusiasts with the powerful H2 but sold a lot of other three-cylinder versions into the 1970s.
Even racers and hard-core enthusiasts of the day were anxious about the Kawasaki H2, especially those who’d ridden its peaky and twitchy 500cc little brother—the 1969 Mach III H1. “Many of us,” says old-school club-racer Jack Seaver, “considered the idea of a 750cc H1 and asked, ‘Are you kidding?’”
But reputation was not reality, and the original H2 was not the dangerous motorcycle popular moto-culture has so churned and embellished into epic proportions. Heck, the thing only made about 65 hp at the rear wheel!
In fact, the H2 was a reasonably competent all-around two-stroke streetbike that just happened to be the undisputed Speed King of the entire motorcycling universe, at least in ’72. Nothing went stoplight to stoplight harder or faster, or with as much visceral, mind-bending thrill, and that sort of performance made folks forget—or forgive—a lot of negatives. Which is exactly what happened in the H2’s case. Because, besides being arguably one of the two or three most legendary Japanese streetbikes of the 1970s, its raft of idiosyncrasies notwithstanding, the H2 is also certainly one of the most desirable today.

The story of the 1972 Kawasaki Mach IV H2 750 begins, of course, with the Mach III H1 of 1969, a 500cc two-stroke triple conceived, designed, and built during the latter 1960s—a time when Kawasaki, new to the US market, was looking to elbow its way in. The peaky-yet-fast H1 did its job well, catapulting Kawasaki—which had only 250cc and 350cc two-stroke twins and a 650cc four-stroke twin—to the top of the performance ladder despite the launch of Honda’s refined (but heavier and slower) CB750 Four that same year. “The Mach II,” wrote Charles Everitt of Motorcyclist Retro in 2008, “was pure Kentucky bourbon, straight up and without a beer chaser…designed to pack the best power-to-weight ratio available and be an absolute menace at the dragstrip, cornering performance be damned.”
