Suzuki's GT750 motorcycle was launched in 1971. The GT750 was Suzuki's competitor in a market populated by the likes of Honda's CB750 and the Kawasaki Z1. The GT 750 was also nicknamed the "Kettle" and the "Water Buffalo", for its liquid cooling system (and also in the latter case its substantial weight).

The GT 750 was unique amongst the other 750CC motorcyles because it had a 3 cylinder water cooled 2 Stroke engine, with a total loss oil lubrication system incorporated in the combustion process. The writing was on the wall for large 2 stroke engines due to emission regulations that were starting to be enforced in the 1970's. Suzuki brought out a 4 cylinder 4 stroke 750 and dropped the 'kettle' 750 2 stroke in 1976/7.

Never intended as a sportsbike, the GT was targeted more at the tourer market, hence the 'GT' nomenclature. Power output of the early models was a claimed 67 BHP, not especially impressive for the time. Handling and braking would, by modern standards, be considered alarming. Top speed in contemporary road tests was around 110 MPH.

In modern times the GT has acquired something of a cult status, mainly due to its two-stroke engine and the historical rarity of liquid cooling in this class.

As an aside, the GT 750 motor was the basis for the 180 MPH racing bike on which Barry Sheene had his infamous high-speed Daytona accident in March 1975. He went on to win the world 500 CC championship in 1976 and 1977.

Suzuki were certainly experimenting with the large motorcyle in the 1970s, they also again uniquely, produced the RE5 a 1000cc rotary (Wankel) engined bike at the same time as the GT 750. Although in some countries the engine measurement system classified it as a 500cc.
