If ever a machine was worthy of the Radar status, it’s the big Kawasaki KZ750. Never heard of it? feel bad, because the is, most people haven’t.

in 1976, the KZ750 was the odd-man-out in lineup, especially considering the new Kawasaki had planned for 1977, included the 4-cylinder KZ650 and Matched up against those two and the carry-over KZ900 four, the 750 quite make sense. its legendary 2-… triples a of the past, Kawasaki’s performance were being defined by cylinders.

So why a big twin?

The vertical twin

the onslaught of big triples and fours, the category was pretty much by vertical twins; or more to the British vertical twins the Royal Enfield Interceptor. Commando and Triumph Bonneville. made some motion the category with the Yamaha vertical twin in 1970, and more so with the Yamaha TX750 years later.

But compared to its rivals the XS650 was considered while the TX750 was a regrettable By the end of 1975, there were only two large vertical on the market, the 750cc Triumph and the 650cc Yamaha XS650.

at from this light, move made sense. the days of Rule Britannia over, there was still a community of riders who wanted a big For that group, the new fours too much.

They had two too many too many camshafts, too many and too many spark plugs. For riders, the best bike defined by quarter-mile performance, it was by ease of maintenance and dependability. And on score, the KZ750 delivered.

Kawasaki’s last big twin, the W650, the KZ750 was thoroughly The 55 horsepower, 745cc twin had overhead cams, shim and valve adjustment, a Morse primary drive chain and forward gears. Vertical vibrate, so Kawasaki gave the 750 a of chain-driven counter balancers.

It worked — mostly. Although at low and moderate rpms, period faulted the twin for a distinct at anything over 4,000rpm, and it would shake itself at anything approaching its 7,750rpm It wouldn’t, it just felt way.

A top speed just of 100mph wasn’t exactly grabbing, but then, the KZ750 a performance machine. Disc front and rear were than adequate to haul the somewhat porky 500-plus-pound to a halt, and were probably chosen because the competing Bonneville had front and rear

Styling of the KZ750 was restrained, a 3.5-gallon gas tank that like it was taken from the parts bin, a long, flat saddle with a rise to the rear but perfect for two, and a restrained little fairing that doubled as a compartment, accessible by lifting the Early bikes featured a helmet lock clamped to the handlebar: Easily defeated, the Allen wrench would net any thief your helmet AND helmet lock.

Early had long mufflers exiting the passenger, and although they right (except for an ungainly seam top and bottom), they the twin’s exhaust note. “If you the way earlier Triumph and BSA twins sounds, you probably won’t be too with the nasal tone of the KZ Cycle World quipped in its review.

Overall, however, testers the big twin good marks. no performance champion, it had more enough power to keep up traffic, and it was stable and predictable in the Excellent fuel economy it a good choice for commuters, and it was a competent touring bike, enough torque to pull passes with ease, of how much gear you packed on it.

The accolades were reserved for its Thanks to its simple but robust the KZ750 earned a reputation for solid dependability, owners on the miles with little than routine maintenance. had gambled that there was a for a simple, reliable big twin, and were right.

By 1978, the 750 was Kawasaki’s fourth biggest in the U.S. and it remained so until the end of the

But the market’s a fickle place, and by the 1980s the KZ750 was out of fashion. tried to give it some new by bobbing the exhaust pipes, the seat, clamping on a set of high-rise (and, curiously, replacing the disc with a drum setup) and calling it the CSR750 to it in step with its successful of street cruisers.

Yet as solid a as the KZ750 twin was, its had come and gone, and the model was for good after 1983. total production is unknown, the success suggests there a lot more KZ750 twins than you’d think, of how many you don’t see today. betting there are literally of them still out there, quietly in suburban garages the country, just waiting to be put on the street.

First available in as the XS-1, the SOHC 650cc XS650 vertical twin was the 4-… and the largest engine had ever built. Inspired by the twins from England, did them one better by offering an oil-tight twin that not wouldn’t spot the garage, it start damn near time. Richly painted and with chrome, Yamaha’s new big threatened to out-British the British at own game.

Until you rode that is. Like almost Japanese bike of its time, the (renamed TX650 in 1973 and XS650 in 1975) had marginal at best. Although close in to the British competition, early simply couldn’t hold a to real Brit twins the Triumph Bonneville and Norton

But that didn’t seem to to most buyers, who were than happy to trade handling for bullet-proof reliability. successful, Yamaha’s big twin was here for 13 years, and many XS consider 1977 the model’s year. An improved frame, brakes, new instruments and a few other made it a better all around while it still retained the look of the early bikes.

and reliable, the XS is possibly the perfect rider.

Well made, torquey and the R80/7 is considered by many BMW as the best of BMW’s ’70s-era twins. With legendary — these are bikes that rack up 100,000 miles ease — and with parts (although not always cheaply) the R80/7 is a classic you can keep on the for decades. MC
