The Aprilia ETX was a family of off-road motorcycles made by Aprilia in Noale, Italy. The bikes were manufactured from 1984 to 2001 in three versions: the 125cc model with a two-stroke engine and the 350cc and 600cc versions with four-stroke engines. The 600cc version never went into production.
In 1989, the Italian bike maker released the Aprilia ETX 350, the larger brother of the 125c model. It debuted in 1985 and continued its production without any significant changes whatsoever.
The bike was built around a steel frame with a hydraulic telescopic fork handling the front suspension and an adjustable shock absorber operating the rear suspension, providing optimum handling capabilities.
The braking performance was achieved by a 260 mm disc mounted on the front wheel and a 230 mm disc mounted on the rear wheel, delivering optimum stopping performance.
Besides the larger displacement engine, the ETX 350 model was similar to the smaller model, featuring 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 1989 Aprilia ETX 350 boasted 33 hp with a peak force at 7,500 rpm and 28 Nm (21 lb-ft) torque at 6,250 rpm, coming from a 349cc four-stroke single-cylinder air-cooled engine placed underneath its fuel tank.
