The Aprilia AF1 125 Sintesi was a sports motorcycle part of the second series in Aprilia's range that debuted in 1988. The bike was slightly different in mechanics and visual departments, offering a more modern appearance.
In 1989, the Italian motorcycle manufacturer launched the Aprilia AF1 125 SIntesi, a sports motorcycle in its second year of production that featured slight visual modifications, giving it a modern approach.
The bike's fairing featured a new design and still two round headlights with a smaller diameter, a new triple clamp with the AF1 logo in the center, a lower handlebar, racing-style instruments, a new fuel tank, and a different suspension setting.
Visually, the bike had standard features, such as a full fairing with a dual round headlight system, a two-piece dual seat, a single exhaust system mounted high on the left side, and aluminum alloy spoke wheels.
In the performance department, the 1989 Aprilia AF1 125 Sintesi had installed a 124cc two-stroke single-cylinder liquid-cooled engine underneath its fuel tank, delivering 28 hp at 10,500 rpm and 18 Nm (13 lb-ft) torque at 10,000 rpm.
The power generated by the engine was controlled by a six-speed manual transmission that sent it to the rear end by a final chain drive, pushing the bike to a top speed of 169 kph (103 mph).
