At the heart of the 2025 Benelli 150S naked motorcycle, Benelli pairs a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 13.1 HP (9.6 kW) at 9,000 rpm while maximum torque reaches 12.5 Nm (9.2 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 87.3 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 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 150S measures 147 kg (324 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,345 mm (53 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank paired with a rated consumption of 2.1 L/100 km provides an estimated theoretical range of roughly 476 km (296 miles) between fill-ups, while factory top speed is listed at 105 km/h (65 mph).
