Featured Listing: 1989 Kawasaki Ninja GPX750R for Sale

Update 6.3.2020: This bike has SOLD! Congratulations to buyer and seller! -dc

Kawasaki’s ZX-7R is finally getting its due and clean, low-mile examples are getting pretty hard to find anywhere near the rock-bottom prices they fetched not too long ago. Older, 1970s and early 1980s Kawis like the KZ1000R have found their collectible niche as well. But the mid-1980s bikes like this Ninja GPX750R have been a bit too new for the classic fans, and too old for anyone into superbikes with more modern looks. So maybe now is the time to start looking for one to add to your collection?

The Ninja name always seemed a little… silly to me, but I’m obviously wrong because Kawasaki still has a bunch of them in their lineup. GPz900R Ninja introduced in 1984 packed a big engine into a lightweight, round tube steel chassis and was very popular, with a great mix of handling and straight line performance. In 1984, Kawasaki took the GPz900’s chassis and dropped a 750cc into it to create the GPz750, a bike with well-rounded and competent but unexciting performance, compared to bikes like the GSX-R750.

An improved engine in 1987 led to the bike seen here, the GPX750R that was available until 1991, depending on the market. That means it would have been available alongside the ZX-7R in some places, long after the GPX would have been considered cutting-edge. Power came from a 748cc sixteen-valve inline four with liquid-cooling and a six-speed gearbox, and the package was good for 141mph. Mechanical anti-dive forks worked well enough, although they and the air-shock out back are obviously not as sophisticated as modern examples. The 16″ front and 18″ rear wheel combo date the bike somewhat, but you still should be able to find decent rubber to fit.

Ultimately, the GPz and GPX750R represent a bit of an in-between stage for Kawasaki, which may be why they’re a bit forgotten today. Performance was perfectly adequate for the class, but they didn’t have exciting new technology or class-leading power. Style isn’t quite Top Gun classic like the GPz900R or World Superbike classic like the ZX-7R, but the GPX750R is supposedly a great bike to ride. If you’re a collector, or just feeling nostalgic, this could be a great candidate. Miles are very low, with a mere 6,065 on the odometer, and overall condition is excellent. There are a few minor blemishes clearly shown in the seller’s photos as you can see from the gallery included.

From the Seller’s eBay listing: 1989 Kawasaki Ninja GPX750R for Sale

At One-Up Moto Garage (https://www.oneupmoto.com) I have high standards for condition and I would rate this Ninja cosmetically 9.5/10 and mechanically 10/10. I am the second owner, the original owner put 95% of the miles on it (totaling just over 6,000). Since day one it has been stored indoors with a bike cover, so it has no sun fading, rust or corrosion. I took pictures of every little chip and blemish I could find on the bike. The tires are nearly new, and carbs were addressed with new float bowl gaskets a few months ago. Not because they were leaking, I just wanted to see how the insides looked- and it was like new (I can send pics upon request). Gas tank also looks new inside. The bike starts easy, runs and rides flawlessly. It has never had ethanol gas in it. Everything feels like new on it, throttle cable is smooth, hydraulics are firm, all switches are tight and snappy.

It spends most of its time in my showroom with the battery tended, I ride it once every few weeks to keep things moving. You won’t be disappointed with this bike! I can send a start, run, and ride video upon request. I can also give you the whole life story of the bike going back to its original sale in Arkansas in 1990. 

Bikes we’ve traditionally considered “classics” are wonderful, but require that you temper your expectations: 1950s motorcycles require more attention and maintenance, have much less power, sketchier handling, and brakes that won’t hold a candle to what even a Ninja 300 can provide these days. The best thing about a bike like this Ninja GPX750R is that it straddles the classic and modern eras. It may not have ABS and an autoblipper, or make 200hp at the rear wheel, and you won’t be able to fit the very best rubber but bikes like this offer good comfort, reliability, and plenty of performance to handle the cut-and-thrust of modern traffic, all while helping you relive your lost youth.

Beast of Boost: 1985 Kawasaki GPz750 Turbo

During the wild years of the decade known as the 1980s, there was a lot going on. Legwarmers were hot. The brat pack were hot. And most importantly, Turbos were hot. Every major Japanese manufacturer played with the puffer configuration at least once (Honda tried it twice) before giving up on induction-enhanced motorcycles. Honda built a pair of large, heavy sport touring bikes. Yamaha built a lazy Seca with futuristic fairing in a “me too” effort. Suzuki took the bonkers approach and built a no-apologies sport bike like a Katana on turbo steroids. And Kawasaki watched, learned, and eventually dipped their toes into the water with an updated GPz.

The largest of the turbo bikes by displacement, the Kawasaki GPz was also the fastest. The only factory turbo bike to break into the 10s in the quarter mile, the GPz 750 Turbo was not only faster than all its forced-induction peers, it was the fastest street bike tested in 1984. With an estimated 112 HP on tap thanks to the Hitachi turbo unit sitting low down and in front of the inline four. With ideal turbo placement for short exhaust primaries, Kawasaki’s approach minimized lag and maximized horsepower. Even then, power windup changes suddenly as the engine builds boost – making for a fun ride, but a less than predictable mount for tight canyons. Like all but the Yamaha, the Kawasaki Turbo introduced fuel injection in an effort to better control engine operations and promote rideability and longevity.

From the seller:
1985 KAWASAKI GPZ750 TURBO

Here’s a real nice Kawasaki 750 Turbo for sale. Bike is in near perfect original condition except for 1 flaw/crack on right lower side of faring. Always stored inside and covered. Runs and rides excellent with fresh oil and filter change. It is all original with factory owners manual and tool kit and has 530 chain conversion to get rid of the factory heavy 630 chain, see last 2 pics. Newer tires and battery.

While the Kawasaki Turbo takes after the GPz models, it differs in many ways. Engine internals, chassis geometry and suspension, and custom factory lowers were all bespoke to the Turbo, although Kawasaki did raid the GPz750 and GPz1100 parts bins to keep costs down. The resultant looks made it familiar to the GPz, yet officially it was known as the ZX750E and referred to simply as the Kawasaki 750 Turbo. Lasting only a couple of years with no significant changes, the Kawasaki GPz750 Turbo shared a similar life cycle with the rest of the Turbo packing offerings. Expensive, complicated and generally unloved, they all failed to sell well in the showrooms – despite the flash and the speed.

Today’s Turbo example is a 1985 model, and it looks like a true survivor. It does not appear to be scuffed, dropped, hot rodded or significantly modified. The seller states that the chain was downsized; the 530 chain is pretty stout, and the factory 630 size was incorporated no doubt due to concerns over longevity. Other than that, this appears to be an honest machine presented to us by a turbo collector (notice the XN85 in the background). The opening ask is a fair $6,999 – but there do not appear to be many bidders as of yet. Not terrifically valuable when compared to more elite machinery (RC30s, OW01, MHe, etc), Turbo bikes are slowly gaining ground as well as the respect of riders and buyers. If you are in the market for one of these unique time pieces, this 10,000 mile machine might be your opportunity. Check it out here, and then jump to the Comments to share your Turbo thoughts. Good Luck!!

Boosted Optimism: 1985 Kawasaki GPz750 Turbo

You are looking at what Cycle magazine dubbed the fastest motorcycle of 1985. Ripping off a quarter mile faster than liter bikes of the day, the Kawasaki GPz750 Turbo took the latest fad and turned it into a very sharp weapon indeed. Easily the most potent of the Turbo set, the GPZ750 Turbo pushed the boosted boundaries further than any of the Big Four. Yet despite the performance possible, Kawasaki failed to achieve success with their Turbo offering – much like the rest of the Big Four. Turbos screamed with graphics, torque and power, but generated few sales.

Kawasaki bolted a Hitachi HT-10B turbocharger in front of the engine, positioned as close to the headers as possible to reduce lag. Utilizing digital fuel injection, the air-cooled, transverse four-stroke in-line four was otherwise comparatively simple in design. Kawasaki engineers raided the parts bin, adding some strengthening to the normally-aspirated GPz750 block handle the Turbo pressure. The top end came from the more conservative KZ650, lowering the compression ratio to a range more compatible with a turbo and pump gas. Expect approximately 95 unfettered horses from this combination.

From the seller:
YOU ARE LOOKING AT A 1985 KAWASAKI GPZ 750 TURBO THAT I HAVE OWNED SINCE NEW. THIS BIKE LIVED ALL OF ITS LIFE IN A CLIMATE CONTROLLED ENVIRONMENT. THE BIKE HAS NEVER HAD FUEL IN ITS TANK, NEVER BEEN STARTED OR HAS HAD ANY ELECTROLYTE PUT INTO THE ORIGINAL BATTERY. MOTORCYCLE WAS PICKLED WHEN NEW AND MAINTAINED THAT WAY THROUGH OUT ITS LIFE. I DON’T KNOW HOW MANY ARE STILL OUT THERE IN THIS CONDITION, I’M THINKING VERY FEW IF ANY. BIKE IS STILL ON MSO, NEVER REGISTERED. I HAVE ORIGINAL OWNERS MANUAL AND BROCHURE. THIS IS A CHANCE TO OWN A BRAND NEW PIECE OF MOTORCYCLE HISTORY. I HAVE MORE PHOTOS IF NEEDED. TIRES ARE STARTING TO SHOW THEIR AGE WITH A LITTLE CRACKING ON THE SIDES, REMEMBER THEY ARE 33 YEARS OLD. PAINT IS FLAWLESS AS IS THE REST OF THE BIKE. PUT IT IN YOUR OFFICE OR MUSEUM , IT IS CURRENTLY IN ONE OF MY LIVING ROOMS.

The Turbo era has remained a relatively underperforming element of the collecting world. Sure, Turbo bikes are rare and unique – and slowly (glacially) gaining in value over the years. However they have failed to ignite the collector world just as they failed to ignite showroom fires back in the 1980s, and just as they failed to deliver on “literbike performance” from a smaller package. One might be willing to call the entire Turbo era a wholesale failure according to nearly every standard by which we compare motorcycles. Those might be harsh words, but the unfortunate reality of this particular segment of our two-wheeled universe. These words, by the way, come from an owner…

This particular Turbo GPz is perhaps the last “new” bike of its type in the world. Zero miles, never filled with fuel and original battery and tires make this a unique find for the right collector. And it would need to be a collector, as after sitting this many years unused, considerable care would need to be taken to turn this back into a rider. But riding it would destroy the value of this zero mile example, making this a museum piece at best. And what price does a brand new 1985 model go for? Would you believe six figures? Me neither. Props to the seller for asking a huge sum, but not riding the fastest quarter miler back in ’85 does not necessarily escalate the value tenfold. Yes, it can only be new once – but few bikes make it to the $100k milestone (and those are far more coveted models). Still, it is a cool time capsule worth looking at. Check it out here, and then jump to the comments and share your thoughts and experiences with Turbo bikes. Good luck!!

Bay Ridge Barn ( well, storage unit ) Find – 1984 Kawasaki GPz-750

Hard as they are to find, unmolested early sportbikes pop up occasionally.  This pre-Ninja 750 appeared on the New York Craigslist recently.

Developed from the KZ-750, the GPz-750 had 92 hp, new frame with Uni-Trak rear suspension, and generally more sport-oriented.  The sweet bikini fairing foreshadows the full fairing to come later.  For 1984, mostly color changes but slightly raising the clip-on handlebars made the bike friendlier.  Rubber front engine mounts helped, too.  The smallish 280mm brakes nonetheless performed well.  Overall a speedy, stable rider.

From the Craigslist ad:

This bike has been very well maintained it’s entire life by a mature older gentleman who kept it in clean, dry, and temperate storage. Pictures do not do this bike justice. The paint is in absolutely stunning original condition. This bike has no mechanical or electrical issues at all and can be ridden anywhere. The carburetors have been jetted and air box has been replaced with air filter pods. Vance and Hines full exhaust looks and runs great with the properly tuned carbs. This bike’s motor pulls strong and has no issues. Chain and sprockets were replaced with new ones last year. Tires are in great condition with no dry rot and lots of tread left. This bike has to be seen in person to truly appreciate how clean it is.

CL ads can be hyperbolic and poorly documented, but this common-sense ad has great pictures.  The GPz-750 was the fastest bike in its day and still has a lot to offer.  The silver paint and red/blue stripes look great, and the bike seems very clean overall.  Sensible asking price for such a pretty historic.  Certainly have to do your homework on a purchase like this but a GPz in such fine shape is worth a look.
