Engineered by Aprilia for the super motard motorcycle segment, the 2025 Aprilia Tuareg 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 80 HP (58.4 kW) at 9,250 rpm while maximum torque reaches 70 Nm (51.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 121.4 HP per liter and a 2,750 rpm working window between peak torque (6,500 rpm) and peak power (9,250 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 Tuareg 660 measures 204 kg (450 lbs) wet (curb), translating to a power-to-weight ratio of 0.39 HP/kg (2.55 kg per horsepower). Rider ergonomics and chassis geometry center around a 860 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,525 mm (60 in) wheelbase engineered for planted straight-line stability. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 4 L/100 km provides an estimated theoretical range of roughly 450 km (280 miles) between fill-ups.
