At the heart of the 2007 Aprilia RX 50 enduro - offroad motorcycle, Aprilia relies on a 49.9 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. 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 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,406 mm (55.4 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.
