The Kawasaki Z1 was to Kawasaki’s success. Thanks to the Z’s underpinnings, Kawasaki was able to variants based on it for the rest of the — and beyond. Its basic architecture a new line of sport bikes in the the GPz series, introduced for 1981 in and 550cc models.

Like all fours before them, the new GPz bikes boasted double cams, plus electronic and triple disc brakes, equipment on any bike with pretentions.

Although the GPz 1100 claim to be one of the first production to sport fuel injection, it necessarily the most technologically bike of its day. That didn’t bother Kawasaki in the slightest, for while GPz’s may lagged in technical terms some bikes, they undeniably fast and fun.

The front row of then-popular club for 550s were heavily with Kawasakis, and the bigger GPz swiftly gained a reputation as an sport tourer.

The 750 arrives

The GPz 750 hit showroom floors in 1982. was directly inspired by its GPz siblings, and its apart from an all-black scheme, looked basically to earlier Kawasaki 650 and 750 fours. Yet examination showed that a amount of work had gone making this 750 special.

New included a revised cylinder ported and polished, and with combustion chambers incorporating placed ridges to induce New pistons with higher helped squeeze the incoming charge, resulting in a compression of 9.5:1. Revised camshaft and new constant-velocity 34mm Mikunis breathing, and an oil cooler kept temperatures in check.

Triple disc with drilled rotors the mechanical package, and an arrest-me-red scheme accented with graphics told the rest of the this was a bike that business.

Kawasaki marketed the GPz 750 as a responsive machine with a power-to-weight ratio — just the for carving canyons or a little competition at the local circuit. a curb weight of just than 500 pounds wasn’t svelte, but with a claimed the 750 could acquit itself out on the road and on the track, where World ran one through the 1/4-mile in 12 seconds. Compare that to the 550 pound, 75hp CB750F and its 1/4-mile times in the high and the GPz’s performance appeal into perspective.

A successful recipe

The GPz’s of go-fast styling and performance massive lust in the sport crowd. In 1982, Don Johnson, the of our feature bike, was in the military, little time to spend in activities such as lap time

Still, in a show of massive to his then-current ride, a 1978 he spent a significant percentage of free time he had eyeing the of the local Kawasaki dealer. a lot of guys, I spent my youth on bikes. They had a 1982 GPz at the dealer, and I used to go up there and pet says Don. “The thought he had a pervert in his dealership. I to buy it, but I got shipped to Germany before I got the together. Ever since I have had a thing for this

Contemporary magazines, equally to Kawasaki passion, enthusiastically the new 750. Any qualms about the of the newest technology (water and 4-valve heads, for example) put aside to cheer the GPz’s power and handling.

Even so, pointed out a lengthy warm up on start, a flat spot in the and a slight buzz through the Yet aside from these the magazines praised the GPz 750 as a versatile, machine that was comfortable to tour on. “The GPz is essentially a high performance spin-off of venerable KZ750E,” said in its October 1982 issue.

One issue mostly ignored by testers was the bike’s height: You had to be the of the average American male to do on the GPz. In 1983, Rider five experienced women and sent them out on a tour of with six bikes, including a GPz 750. Most of the women found that ergonomic seriously dampened their of the GPz. “It’s big, powerful, and it does not compromise,” Ms. Dorde Woodruff, adding, “It the most difficult for our group.”

The found the bike’s forward position and 31.5-inch seat hard to cope with. On twisty roads, Ms. Woodruff the BMW R80ST her group also “The Kawasaki was too much and a little scary for me there,” she

“I must have been the ergonomic guy when they the GPz,” Don says, noting his 10-inch frame fits the perfectly. He takes it on forays the local hills, and has no problems the somewhat rearset pegs or the bars. “As a matter of fact, a great bike around he adds.

In 1983, Kawasaki modified the GPz, giving it a new shock frame, a full fairing in place of the little fairing on the first bikes, and a radical engine. Compression to 10.5:1 and horsepower to a claimed providing more speed at the of the 1982 bike’s versatility. there was muted criticism of technology — or perceived lack — in some corners, it was quieted for a when Wayne Rainey, for Muzzy Kawasaki, won the AMA Superbike on a race prepped GPz 750 in 1983.

The 1984 version lost the lowers and gained more bars, while for 1985 the bars stayed, but the lowers back. However, 1985 was the year for the air-cooled GPz. By time, Kawasaki had its next liquid-cooled Ninja sport ready. Yet not everyone was in favor of progress.

As Cycle World in 1985, “All in all, the GPz is a motorcycle. But satisfying may not be enough for longer. It’s likely to be next year with a 750 a motorcycle that will not just more performance, but cost and complexity, as well.”

Don gets his GPz

Don Johnson came from his tour in Germany and his love affair with He eventually started collecting including the 1970 Triumph sitting in his living room. Yet he found himself thinking that GPz in the dealer’s showroom way when, and idly reading the last winter, he saw an ad for a 1982 GPz 750.

Don immediately got on the horn and photos, which showed a stock, nicely kept He was ready to dash out to the seller’s when reality hit — it was winter, all, and the trip would been complicated. So he called his Mike, who lives below the line where the bike was and Brother Mike agreed to go at the bike, and buy it if it looked as nice as the in the photos.

Seeing the bike, duly called, reporting, it looks even better the photos. Are you sure you want it? If you I’ll keep it.”

Mike bought the bike and it home, and as soon as Don was able to, he up with a trailer, ready to up with Brother and take the GPz It was in comfortable running condition, but had an seat, lacked the stock rail, and had some paint caused by a leaky battery.

“I the search for a correct seat,” Don “I found one after two hours on a enthusiast website. A friend is good with upholstery, and the two of us to merge the two seats so I had one correct Then I went looking for a rail.

The guy who had the seat told me, ‘I I had known you needed a grab I would have thrown it the box with the seat.’”

Don repaired it and the battery box, baking it in the oven to give it a hard He replaced hoses, caps and rounded off bolts, and changed out the oil, the air filter, and the oil and oil filter. I get a bike home, I change all as a matter of course,” Don says.

Don says that the GPz is at its best on roads in the hills. “It keeps up traffic, changes lanes has good brakes and good You don’t have to worry being run over by the car behind It isn’t a super handler by standards, but it’s good. never pushed it very but it won’t embarrass you on a mountain

Don also says the bike well on the freeway. “The is comfortable. There’s slight in the bars, but not to the point where a bother.” And while he didn’t buy the GPz for he thinks he would notice if the GPz was thirsty. “It seems about for a bike of this displacement,” he Period testers got between miles per gallon, depending on how they were pushing the

Summing up his love for his GPz, Don back to the first time he a 750. “It’s a chemistry Don explains. “It’s something has been with me since I like classic-y bikes in and the GPz is classic. I love the way it looks and and sounds. It’s a classic a performance slant.” MC
