The Aprilia ETX was a line of off-road motorcycles manufactured by Aprilia in Noale, Italy, from 1984 to 2001. The bikes were produced in three versions: the 125cc model with a two-stroke engine and the 350cc and 600cc versions with four-stroke engines.
The first model was introduced in 1984 under the Aprilia ETX 125 designation, the smaller one in the range. It was manufactured between 1984 and 2001 until it was replaced by the Tuareg 125 version that featured a larger fuel tank.
In 1985, the Italian motorcycle manufacturer launched the Aprilia ETX 350, the second model in the series, which was manufactured until 1987. The bike was set in motion by an air-cooled four-stroke SOHC engine, unlike the 125cc two-stroke, coupled to a five-speed gearbox and fed from a 14-liter fuel tank.
The bike was built around a steel frame with a hydraulic telescopic fork on the front and an adjustable shock absorber on the rear, providing optimum suspension performance and handling.
The braking power was handled by a 260 mm disc mounted on the front wheel and a 230 mm disc mounted on the rear wheel, delivering optimum stopping performance.
As for power, the 1985 Aprilia ETX 350 had its soul brought to life by a 349cc four-stroke single-cylinder air-cooled engine managed by a Dell'Orto carburetor, delivering 33 hp with a peak force at 7,500 rpm and 28 Nm (21 lb-ft) torque at 6,250 rpm.
