In 1998, the Italian motorcycle manufacturer launched the Aprilia AF1 125 Project 108 Replica, as its name suggests, a replica model that celebrated the Grand Prix San Marino race won by Luca Reggiani Misano on August 30, 1987. The bike was sold in December 1987.
Compared to the base model, the Replica version was the same elegant, sporty, and well-managed motorcycle, with a more vibrant color than its sister model. Compared to the standard AF1, the replica version featured several modifications.
Some modifications included a redesigned fairing, a larger tail, a dual round headlight system, a wider windscreen, and a removable passenger seat cover. In addition, the instrument panel, electrical controls, fuel tank, battery, air filter, and other components remained unchanged.
The bike's aesthetic department was characterized by standard fittings such as a full dress with two round headlights, a windscreen, a single seat with a passenger seat cover, a single exhaust system with a silencer mounted on the left side, a single-sided swingarm, and three-spoke aluminum wheels.
In the power department, the 1988 Aprilia AF1 125 Project 108 Replica took its muscles from a small-displacement 125cc two-stroke liquid-cooled single-cylinder engine mounted at its core, delivering an output power of 25 hp with maximum strength at 10,000 rpm and 18 Nm (13 lb-ft) torque at 8,000 rpm.
