The GT 125 was released by Suzuki in 1974 as the smaller sister of the GT 185. The bike had a shorter wheelbase and smaller engine displacement than the 185 GT and also the electric starter was sacked to make it more affordable. The GT series was regarded as a good beginner class at the time.


The engine was a air cooled twin, two-stroke. A 43.0mm bore x 43.0mm stroke result in a displacement of just 125.0 cubic centimeters. Fuel was supplied via a port control.


The bike has a 5-speed transmission.


It came with a 2.75-18 front tire and a 3.00-18 rear tire. Stopping was achieved via single disc in the front and a expanding brake in the rear. The GT125 was fitted with a 2.64 Gallon (10.00 Liters) fuel tank.
