The Aprilia AF1 was a sports motorcycle designed, developed, and produced by Aprilia between 1986 and 1993. The bike was available in two versions, 50cc and 125cc. The AF1 125 was manufactured in various series with numerous modifications.
The Aprilia AF1 125, also known as the AF1 125 Project 108, debuted in 1987, packing a 124cc single-cylinder Rotax V 127 liquid-cooled engine coupled to a six-speed transmission that developed 27 hp, launching the bike to 158 kph (98 mph).
In the visual department, the bike had standard features, such as full fairing with a rectangular headlight, a small windscreen, a one-piece dual seat with passenger grab handles, a single exhaust system with a silencer mounted on the left side, a single-sided swingarm, and three-spoke aluminum wheels.
The front end was handled by a four-way anti-dive-adjustable telescopic fork, while the rear end was controlled by a Sebac shock absorber, offering optimum suspension performance and handling.
The bike glided on 16-inch three-spoke aluminum wheels fitted with a 260 mm brake disc on the front and a 240 mm brake disc on the rear, delivering optimum braking performance.
At its core, the 1987 Aprilia AF1 125 Project had installed a small-displacement 123cc two-stroke liquid-cooled single-cylinder engine managed by a Dell'Orto carburetor, delivering 25 hp at 10,000 rpm and 18 Nm (13 lb-ft) torque at 8,000 rpm.
