The Aprilia ETX was a line of off-road motorcycles made by Aprilia in Noale, Italy. The bikes were manufactured in three versions: the 125cc model with a two-stroke engine and the 350cc and 600cc versions with four-stroke engines.
In 1986, the Italian motorcycle manufacturer launched the Aprilia ETX 350, the second model in the series that debuted in 1985 and continued production until 1987. It was in its second year of production and packed the same specifications as the previous model without changes.
Besides the larger displacement engine, the ETX 350 model was similar to the smaller model, packing standard fittings, such as a high-mounted front fender, a small front cowl with a rectangular headlight, a one-piece dual seat, a luggage rack, an under-seat-mounted exhaust, and wire-spoke-wheels.
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.
In the braking department, the motorcycle packed a 260 mm disc mounted on the front wheel and a 230 mm disc mounted on the rear wheel, delivering optimum stopping performance.
In the performance department, the 1986 Aprilia ETX 350 had installed a 349cc four-stroke single-cylinder air-cooled engine with 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.
