Suzuki GT750

The Suzuki GT750 was a in-line three, two-stroke Sport touring motorcycle produced by Suzuki between 1972 and 1977. It could reach a top speed of 119 mph (192 km/h). Max torque was 61.22 ft/lbs (83.0 Nm) @ 5500 RPM. Claimed horsepower was 61.69 HP (46.0 KW) @ 6500 RPM. This bike is heavy, comfortable, economical and extremely smooth, the GT 750 is capable of high 13/seconds standing start quarter miles. This Suzuki motorcycle was known as the Water Buffalo to many riders, also known as The Kettle in the U.K., Suzuki had officially nicknamed it the Le Mans. It was a 750cc 2-Stroke triple.

Engine[edit]

The engine was a liquid cooled in-line three, two-stroke. A 70.0mm bore x 64.0mm stroke result in a displacement of just 739.0 cubic centimeters. Fuel was supplied via a port control.

Drive[edit]

The bike has a 5-speed transmission. Power was moderated via the Wet multi-disc.

Chassis[edit]

It came with a 3.25-19 front tire and a 4.00-18 rear tire. Stopping was achieved via dual disc in the front and a expanding brake in the rear. The front suspension was a Telescopic Fork while the rear was equipped with a Swinging Arm Fork With Adjustable Shock Absorber. The GT750 was fitted with a 4.49 Gallon (17.00 Liters) fuel tank. The wheelbase was 57.52 inches (1461 mm) long.



Two by Three[edit]

The early 1970s showed Kawasaki and Suzuki's response to Honda's already legendary CB750K by inaugurating the new technique of transverse three-cylinder two-stroke engines. Just as theTriumph Trident was in simple terms, one and a half of the their 500cc twin, the GT750 shared the 70x64mm bore and stroke dimensions of the T500 along with similar porting. If the layout was the same, the offerings of the two rivals represented very different philosophies. The air-cooled Kawasaki H2 was a supersports machine with out-of-the-ordinary performance: over 125 mph top speed and a standing quarter in 12.1 seconds. The Suzuki was a real GT: heavier, larger and with a water-cooled engine.

Two Errors of Judgment[edit]

Suzuki's main error lay in not having foreseen the trend of the market towards sportier machines. A second fault was retaining a front drum brake while Honda, Kawasaki (on its H1 500 and 750) and Yamaha (on the XS650) had already opted for discs. They would later almost over correct (in a positive manner) all these errors in the 80s with their introduction of the Suzuki GSX-R750.

Extraordinary Track Machine[edit]

Built until 1977, when it appeared in the catalog alongside the four-stroke GS750, the GT took a long time to build up its image. It was small consolation that it had spawned an extraordinary track machine, the TR750.

However, the GT was an excellent touring mount which marked a turning point in the history of the two-stroke. Reliable and mechanically silent, possessed of remarkable torque, it was a docile road bike, unlike the Kawasaki, which was brilliant but noisy and guzzled gas.
