The Aprilia ETX 125 was a pivotal motorcycle in the brand’s history, marking the first mass-produced model to feature a Rotax 126 engine from Austrian company Rotax. This 125cc powerhouse boasted a unique character, thanks to its reed valve induction and forced circulation cooling system.
As you swing your leg over the sleek ETX, you’ll be greeted by its sporty lines and well-designed superstructures. The instrumentation is comprehensive, with a water thermometer cleverly placed on the radiator itself, accompanied by CEV’s beautiful electrical blocks.
Riding the ETX 125 is an exhilarating experience, thanks to its responsive handling and impressive power delivery. With a maximum speed of 121.5 km/h and a peak power output of 18.28hp at 8250 rpm, this motorcycle was a thrill to ride in its time.
