Positioned in Aprilia's sport motorcycle lineup, the 2021 Aprilia RS-GP relies on a 999.6 cc (61 cu in) liquid-cooled v4, four-stroke powerplant. In factory specification, peak output is rated at 255 HP (186.1 kW) at 13,000 rpm while maximum torque reaches 115 Nm (84.8 lb-ft) at 10,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 255.1 HP per liter and a 2,500 rpm working window between peak torque (10,500 rpm) and peak power (13,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the RS-GP measures 160 kg (353 lbs) wet (curb), translating to a power-to-weight ratio of 1.59 HP/kg (0.63 kg per horsepower). Rider ergonomics and chassis geometry center around a 840 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 22-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 350 km/h (217 mph).
