Technical Overview
2006 Aprilia Pegaso 650 Strada Technical Analysis & Specification Breakdown
Engineered by Aprilia for the naked motorcycle segment, the 2006 Aprilia Pegaso 650 Strada utilizes a 659 cc (40.2 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 50 HP (36.5 kW) at 6,250 rpm while maximum torque reaches 61 Nm (45 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 75.9 HP per liter and a 1,000 rpm working window between peak torque (5,250 rpm) and peak power (6,250 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,479 mm (58.2 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
