2022 Aprilia SR GT 125 Technical Analysis & Specification Breakdown
Built around Aprilia's scooter motorcycle platform, the 2022 Aprilia SR GT 125 pairs a 124.5 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 8,700 rpm while maximum torque reaches 12 Nm (8.9 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 118.9 HP per liter and a 2,200 rpm working window between peak torque (6,500 rpm) and peak power (8,700 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the SR GT 125 measures 115 kg (254 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.77 kg per horsepower). Rider ergonomics and chassis geometry center around a 799 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
