Technical Overview
1991 Aprilia F1 Sport Pro Replica Technical Analysis & Specification Breakdown
Built around Aprilia's sport motorcycle platform, the 1991 Aprilia F1 Sport Pro Replica features a 125 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 25 HP (18.2 kW) while maximum torque reaches 16 Nm (11.8 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 200 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the F1 Sport Pro Replica measures 150 kg (331 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (6 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 161 km/h (100 mph).
