Built around Aprilia's scooter motorcycle platform, the 2021 Aprilia SXR 160 relies on a 160 cc (9.8 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.8 HP (7.9 kW) at 7,100 rpm while maximum torque reaches 11.6 Nm (8.6 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 67.5 HP per liter and a 1,100 rpm working window between peak torque (6,000 rpm) and peak power (7,100 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the SXR 160 measures 129 kg (284 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (11.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,353 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
