The GT500 is equipped with a 500 cm³ 2-stroke air-cooled 2-cylinder engine that generates maximum horsepower of 47 PS and maximum torque of 53.9 N·m. The styling combines essential motorcycle design elements such as a down type muffler, large-capacity 14.5-liter fuel tank, and chrome-plated fenders to create a new image full of power and presence. This model positions the switches for the headlight, position lights, turn signals, and horn close to the rider’s left hand to enable speedy operation. The pillion seat has a deluxe appearance and reduces fatigue even during long-distance touring. The speedometer also features a built-in trip meter.

The GT550 is equipped with a 550 cm³ 2-stroke 3-cylinder engine that generates maximum horsepower of 50 PS and improved power at low rpms. Combined with the outstandingly effective Ram Air cooling system, which was developed by Suzuki with inspiration from airplanes, this model can be ridden with greater reliably for long distances at high speeds. In addition, adopting a quad muffler for the three cylinders lowers the frequency of the exhaust note and helps to boost power at low rpms. Thorough attention was also paid to the improvement of basic performance in the engineering design, such as the adoption of a highly efficient hydraulic disc brake at the front wheel.
