2008 MV Agusta F4 Ago Technical Analysis & Specification Breakdown
Positioned in MV Agusta's sport motorcycle lineup, the 2008 MV Agusta F4 Ago pairs a 748.9 cc (45.7 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 143.9 HP (105 kW) at 13,000 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 192.1 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,398 mm (55 in) wheelbase engineered for quick, flickable steering geometry.
