Engineered by Aprilia for the sport motorcycle segment, the 1992 Aprilia AF1 125 pairs a 125 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 54.0 x 54.5 mm (2.1 x 2.1 inches) with a 12.5:1 compression ratio.
On the scales, the AF1 125 measures 115 kg (254 lbs) dry. Rider ergonomics and chassis geometry center around a 1,360 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 3.62 L/100 km provides an estimated theoretical range of roughly 414 km (257 miles) between fill-ups, while factory top speed is listed at 160 km/h (99 mph).
