Kawasaki GPZ 750 Turbo: Blow hard!

We love the Kawasaki GPZ750 Turbo...!!!
Kawasaki GPZ 750 Turbo Kawasaki GPZ 750 Turbo

Kawasaki’s most powerful motorcycle ever - the ZZR 1400 - packs 197bhp and sure, it's insane. But it still doesn't have a turbocharger, which the 1980s GPZ750 did! Oh, okay, given the added weight, cost and complexity, turbochargers on motorcycles aren’t probably worth the hassle. But then, a ‘factory turbo’ badge has to be worth a point or two down at the pub, swapping tales over a pint. Wind on the boost, and from stoplights, the mid-1980s GPZ Turbo will still leave your neighbour’s Porsche Cayenne for dead. This bike was, after all, the first production motorcycle ever to run the quarter mile (400m) in less than 11 seconds.
The bike featured digital fuel injection and was fitted with a Hitachi HT-10B turbocharger. Power output, in stock form, was 95bhp, but with a bit of fettling and tweaking, some tuners claim to be able to release more than 200bhp! Said Motorcyclist magazine, in October 1983, "The 750 Turbo is far more than the hottest. It's a milestone in motorcycling." Many will argue that the normally-aspirated GPZ 900R was the better machine, but come on, everyone should own at least one turbocharged motorcycle, at least once in their lives...

Yes, the GPZ750 Turbo was a bit special...

You are right buddy. The Gpz is one of my dream bikes too. Though Kawasaki was the last to realease a turbo, it packed the most punch.

Although I remember it as the power rating was a 110bhp and not 95. It weighed in close to 496lbs (that's 225KGs) and a 5 speed gearbox. Some features included, anti-dive forks, Uni-Trak rear suspension.

Although looks-wise I'd say the Yamaha xj650 had it beat, and the suzuki xn85 had the yammie beat.

But in terms of sheer outright power, it was the Kawi.

The xj and xn85's have been reduced to curios by time, but the old beastie turbo with a few tweaks is still a very viable bike to go fast on even today...
I know, im putting 200 miles a week on one of my pair...

With the right modifications this bike will outrun a ZZR1400 and go over 200mph.

Not a lot out there to beat a Turbo. I still have one sitting nicely in my garage and on the rare occassion that it rears its beastly head, there are still very few machines to match it.

I owned one briefly in the mid 80s - still miss it

I had the choice of a GPZ 900 or one of these blighters, the lure of the turbo badge made the decision for me!

It was flamin' marvellous in a straight line but it bit wobbly round the back lanes - a friend of mine stuck one in a Harris frame and said it made the handling even worse, something to do with the rake ... As if mine didn't have a hinge in the middle!

I owned owned a turbo for 4 years,then when i sold it i bought my brothers gpz900,the turbo was a much better bike in my opinion,but i had come from an H1 500 before,so maybe i liked the 2 stroke like power hit.
I sold it to a friend who still owns it,december 07,it will still out drag a lot of newer bikes, as it has a bleed valve on the wastegate,regularly run on 14lb boost,clutch starts slipping about 22lb boost.

I'm in the process of building a radical custom turbo kawasaki. The platform is a ZN1300 voyager. It's a 1300cc, inline 6, fuel injected. It wass completely stripped down. Custom bars, frame rails, exaust, seat, lights, gauges, controls, wheels, fueltank, fenders, etc.
The I've lightened it by well over 300 lbs. With the healthy 120hp 6 cylinder motor this thing "RIPS". It's just about ready for the road.
I'm putting together the turbo set up over the next few months. A dynatech programable ECM, A garrett ballbearing turbo, forged pistons, custom camshaft, larger injectors. It should be interesting.

Back in 84 I rode my brand new 900 Ninja to Cali and wound up meeting and riding with a fellow on a GPZ750 turbo.

Ever since then I've dreamt of a a turbo bike! A few years ago I found oldskoolsuzuki.info and there I learned how to Turbo-charge a bike. I now have a blow through GSXR1100G Streetfighter making 250HP on the street.

I owe it all to the GPZ750 Turbo!!

Cheers,

Hey Boys...I have been riding on two wheels for 30 years...have ridden just about everything...I am now a die hard Harley man but owned and would with out a secoind thought own one of these bikes again...Great Bike...

I purchased a 550 Gpz out of the box in 84 and still have it. It's a great bike. My buddy had the 750 turbo and I could not believe how sick the speed was in that machine. It would leave you if you were not hanging on. I don't think that insurance gecko will allow a legend like the turbo to roam the halls ever again. 134 at altitude...pretty fn fun...

I am from South-Africa. I have the Kawasaki 750 turbo now for 5 months, and is still one of the best bikes ever built. I still give the fireblades a run for there money and remember this year is the bike 27 years old and still like a rocket.
Thanx KAWA !!!

It is a bit modded and now has a TD04 Turbo.
The thing is with this bike , is that it hust for men with balls. ;)

...1st off i believe twas 115bhp...i owned a 1984 version from 1986-1990...Man, i'll never ever forget that furious boost delivered when pulling that throttle, even when accelerating from 40-95mph...nothin i've ever ridden yet to this date has given me that real immediate awaredness to hold the heck on for dear life!!!...it couldn't handle for jack, but give it somewhat of a straight-away and you best hold on!!...Me and the wife back then had it flying over the Bay-bridge towards San Francisco one evening, around 11pm, with my digital reading 137mph before i ran outta room fast...she damn near never spoke to me again after that, but it was way worth it!!!..i hope to Own one again someday!!!

Had 3 Yamaha 650 Turbos, great bikes, but nothing even close to my 750kawi turbo.Had one of the first ones to come to the country.Installed D&D lightweight exaust, smaller rear sprocket,adjustable boost and always ran aviation fuel. It was one scary rocket. Never got beat
and never had the balls to find out how fast it would really go, top end. What a thrill to haveowned
such a machine. Only those of us lucky enough to have had the privlegeof ridingone of these machines will understand. Regret the day I sold it and hope to find and purchase another one.

The 112 bhp is at the crank, and 95 bhp is at the wheel. I own this bike and you can feel the boost is gradually building. Of course, its suspension, wheels, and chassis design hasn't really changed since first Z1 came out (except this one has a mono-shock), there are some limitations. And Kawasaki deliberately lowered the horsepower to make sure it doesn't beat GPz1100. It still has an ability to raise horsepower to maybe 120 or 150 bhp for regular street riding.

I have both 750 turbo and GPX750R (Ninja 750R). They are both different bikes. GPX, since it was the 1st Kawasaki to be designed with CAD, the chassis design is significantly better, as it's design is also on ZRX1100/1200 and ZR-7's. So handling is better on the GPX.

Bought my 750 turbo in 1986 as it was love at first sight - had 8000 km on the clock and now has 455000km and has been rebuilt every 100000km turbo and all. Taken it around Australia and was my main ride for 5 years. Reliable, fast and still a head turner and close to showroom condition although in the last 7 years it gets ridden less it is something I truly look forward to. It's the E2A limited edition model for Australia. Great to see so many other turbo owners who share the same passion I have.

I have purchased a 1985 GPZ Turbo E2 from the US and cannot wait for it to arrive. Reading all your story’s just makes me itch even more. Truly a legendary bike.

I've got one in my shed, waiting for a new cam chain and, and a cylinder head that's ready to fit. Currently running a ZZR1100, but itching to get back on the Turbo. Handling was rubbish, with a wobble that started at any speed over 85mph, but you'd never know when. Now fitted with ZZR600 forks, brakes and 17" wheels, lost a load of weight by replacing exhaust. Don't know if it's still got a wobble, but it's been solid up to 135mph.That's where I run out of balls. Best 750 ever.
