The Suzuki GN125 motorcycle was produced by the Suzuki Motor Corp. from the early 1980s to 2001, as part of Suzuki's GN series of beginner-level two-wheelers that were built in the 1980s. It's been called "a tough little bike," "modest but useful" and "incredibly easy to ride" by Motorcycle News. Although it is no longer in production, you can buy a Suzuki GN125 if the technical specifications meet your needs.


The GN125 has a 124cc, 2-V single cylinder engine, which means it has one intake and one exhaust valve in the head per cylinder. The engine is air-cooled and has five gears. Its torque is 7 feet per pound. The engine power is 12 horsepower.


The GN125 typically weighs about 104kg. and has a seat height of just under 29 inches. The motorcycle has a steel cradle frame.


The standard GN125 dashboard features a speed gauge, rpm dial and two wide rear view mirrors--one on the left side and the other on the right side of the dashboard. The dashboard does not feature a fuel gauge.

Fuel Efficiency

The GN125's fuel tank capacity is 2.6 gallons, but its average fuel consumption is about 80 miles per gallon (mpg), so one tank typically lasts at least 175 miles. The motorcycle's top speed is about 70mph, depending on the year of production.

Brakes and Suspension

Each model of the GN125 has single disc front brakes and drum rear brakes. Motorcycle News called the GN125's brakes "lousy." The motorcycle has no front suspension adjustment and a preload rear suspension adjustment.


The GN125's front tire size is 90/90 by 19 and the rear tires are 100/80 by 18 for each year of production.
