Positioned in Aprilia's sport motorcycle lineup, the 2025 Aprilia Tuono 660 pairs a 659 cc (40.2 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 95 HP (69.3 kW) at 10,500 rpm while maximum torque reaches 67 Nm (49.4 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 144.2 HP per liter and a 2,000 rpm working window between peak torque (8,500 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Tuono 660 measures 183 kg (403 lbs) wet (curb), translating to a power-to-weight ratio of 0.52 HP/kg (1.93 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 4.9 L/100 km provides an estimated theoretical range of roughly 306 km (190 miles) between fill-ups.
