Suzuki GT750 1971—1977

Suzuki GT-750 Wasserbuffel

1971 GT750 The first year's model of GT750 model was never available in the shops. Suzuki managed to get the bike to the market first in 1972.

The GT750 was unveiled to much fanfare at the 1971 Tokyo show. This was Suzuki's answer to the Honda CB750, and the Kawasaki H2, but was very different to both. Driven by an in-line 3 cylinder 2-stroke engine, the 'Water Buffalo' was also liquid cooled.

Suzuki surprisingly opted for drum brakes (on the original), but the front was a 9 inch 4-leading shoe design, so was actually reasonably powerful. The engine was very impressive, with a nice flat torque curve, and good acceleration from as low as 2000 rpm.

Like the T500, the GT750 got top marks for handling and comfort. Detailing on the bike was also of an exceptionally high standard. Clearly, Suzuki wanted this flagship machine to represent the Company in the best light possible.

The engine firing impulses corresponds to that of a 6-cyl 4-stroke so this engine type runs very smoothly when in good tune. Visually if you meet one on the road, these bikes are distinguished by the characteristic water cooling radiator in front of the engine. If one runs ahead of you on the road a smell of three 50cc 2-stroke engines and possibly some bluish 2-stroke smoke may be noticeable.

There is a cooling fan behind the radiator which kicks in at random occasions. It is never needed. The engine has electric start. The GT750 is commonly referred to as the 'Water Buffalo' (U.S) 'Wasserbüffel' (Germany), 'Vattenbuffeln' (Sweden), 'The Kettle' or Water Bottle' (Britain), 'Vannbuss' (Norwegian!) or 'waterbucket' (Australia). In advertising it was also named the 'LeMans' in the U.S.

This machine type was known for the wide power band/low end torque allowing exceptional acceleration performance from low revs, similar in characteristics to the triple 2-stroke air cooled Kawasaki H2 750 (Mach IV) but more 'civilised'.

It was more popular as a touring bike than a stop light racer due to weight/dimensions, but it can be a performer. The main flaw of the J series is the brakes are no match for the acceleration capability and weight (507lbs dry/230kg) (front dual drum brake, the 1973 K model had dual front discs) so some caution is required in order to stay alive.
