1999 Aprilia Pegaso 650 Technical Analysis & Specification Breakdown

Positioned in Aprilia's enduro - offroad motorcycle lineup, the 1999 Aprilia Pegaso 650 features a 652 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 49 HP (35.8 kW) at 6,300 rpm while maximum torque reaches 54 Nm (39.8 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 75.2 HP per liter and a 1,300 rpm working window between peak torque (5,000 rpm) and peak power (6,300 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the Pegaso 650 measures 201 kg (443 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.1 kg per horsepower). 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 paired with a rated consumption of 6.7 L/100 km provides an estimated theoretical range of roughly 328 km (204 miles) between fill-ups, while factory top speed is listed at 166 km/h (103 mph).
