Engineered by Aprilia for the sport motorcycle segment, the 1987 Aprilia AF 1 125 Replica relies on a 123.7 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 25 HP (18.2 kW) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 202.1 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the AF 1 125 Replica measures 147 kg (324 lbs) wet (curb), translating to a power-to-weight ratio of 0.17 HP/kg (5.88 kg per horsepower). The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 156 km/h (97 mph).
