2017 Aprilia SR Motard 125 Technical Analysis & Specification Breakdown
At the heart of the 2017 Aprilia SR Motard 125 scooter motorcycle, Aprilia relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 9.6 HP (7 kW) at 8,500 rpm while maximum torque reaches 8.2 Nm (6 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 77.4 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 SR Motard 125 measures 122 kg (269 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.71 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
