Built around Aprilia's scooter motorcycle platform, the 2025 Aprilia SR GT Replica 125 utilizes a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 8,750 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 118.4 HP per liter and a 2,250 rpm working window between peak torque (6,500 rpm) and peak power (8,750 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 Replica 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 paired with a rated consumption of 2.59 L/100 km provides an estimated theoretical range of roughly 347 km (216 miles) between fill-ups.
