Engineered by Aprilia for the sport motorcycle segment, the 2025 Aprilia RS 457 pairs a 457 cc (27.9 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 47.6 HP (34.7 kW) at 9,400 rpm while maximum torque reaches 43.5 Nm (32.1 lb-ft) at 6,700 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 104.2 HP per liter and a 2,700 rpm working window between peak torque (6,700 rpm) and peak power (9,400 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 RS 457 measures 175 kg (386 lbs) wet (curb), translating to a power-to-weight ratio of 0.27 HP/kg (3.68 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,349 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank paired with a rated consumption of 4.13 L/100 km provides an estimated theoretical range of roughly 315 km (196 miles) between fill-ups.
