Engineered by Aprilia for the enduro - offroad motorcycle segment, the 2015 Aprilia RX 50 pairs a 49.9 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 39.9 x 40.0 mm (1.6 x 1.6 inches).
Rider ergonomics and chassis geometry center around a 880 mm (34.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,412 mm (55.6 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Aprilia archive, this model family spans 15 indexed model years from 2002 to 2022, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
