2009 Aprilia Mana 850 ABS Technical Analysis & Specification Breakdown
Positioned in Aprilia's naked motorcycle lineup, the 2009 Aprilia Mana 850 ABS features a 839.3 cc (51.2 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 75.1 HP (54.8 kW) at 8,000 rpm while maximum torque reaches 73 Nm (53.8 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 89.5 HP per liter and a 3,000 rpm working window between peak torque (5,000 rpm) and peak power (8,000 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 Mana 850 ABS measures 181 kg (399 lbs) dry, translating to a power-to-weight ratio of 0.41 HP/kg (2.41 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,463 mm (57.6 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.
