Positioned in Aprilia's super motard motorcycle lineup, the 2007 Aprilia SX 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) with a 11.5:1 compression ratio.
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.
Within MotoLibrary's Aprilia archive, this model family spans 14 indexed model years from 2007 to 2022, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
