2007 Piaggio X9 Evolution 125 Technical Analysis & Specification Breakdown

Positioned in Piaggio's scooter motorcycle lineup, the 2007 Piaggio X9 Evolution 125 relies on a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 39 HP (28.5 kW) at 10,000 rpm while maximum torque reaches 12 Nm (8.9 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 314.5 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the X9 Evolution 125 measures 179 kg (395 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.59 kg per horsepower). 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 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 15.2-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
