2006 Aprilia RX 50 Racing Technical Analysis & Specification Breakdown
Built around Aprilia's enduro - offroad motorcycle platform, the 2006 Aprilia RX 50 Racing pairs a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches) with a 12.0:1 compression ratio.
On the scales, the RX 50 Racing measures 98 kg (216 lbs) dry. Rider ergonomics and chassis geometry center around a 940 mm (37 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,400 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
