Best press quote:
"The 750 Turbo is far more than the hottest. It's a milestone in motorcycling."
Motorcyclist, October 1983

No factory turbocharged motorcycle came closer to fulfilling "the promise" (liter-bike performance in a middleweight package) than Kawasaki's GPz750 Turbo. It was simply the fastest thing you could buy on two wheels at the end of 1983 (it was an early-release '84 bike). Acceleration was an arm-ripping, eyeball-squashing experience that's still impressive to this day. And to think that Kawasaki "detuned" it just before it was released (or should we say, unleashed) to the motorcycling public.

Sporting a Hitachi HT-10B turbocharger positioned close to the headers and utilizing digital fuel injection the GPz Turbo was comparatively (turbo-ly speaking) simple in design. The GPz750 engine on which it was based needed only minor strengthening to handle the Turbo's 95 horses. The conservative valves and cylinder head came straight off the KZ650 (the better to keep all that pressure under wraps, my dear).

Handling was, in a word, stable, or if you prefer, truckish. Yes, it had to be muscled through corners and had a harsh, over-damped ride, but if you liked high speed blasts the chassis was supremely stable. Swapping the stock Michelin tires for Perrellis or, better yet, Metzelers, lightened steering effort considerably with only a marginal lessening of high-speed stability (a good trade off).

Be prepared to pay between $2,500 and $4,500 for a clean, low-mileage 750 Turbo today. Showroom examples can set you back $5,000 or more. Engine performance can be greatly increased - how does 230 hp grab ya? Contact the T.M.I.O.A. for details.
