Engineered by Aprilia for the enduro - offroad motorcycle segment, the 2002 Aprilia Pegaso 650 pairs a 651.8 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 100.0 x 83.0 mm (3.9 x 3.3 inches) with a 9.1:1 compression ratio.
On the scales, the Pegaso 650 measures 161 kg (355 lbs) dry. Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 22-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
