In 1987, at the Milan Show, the Italian motorcycle manufacturer presented the Aprilia AF1 125 Project 108 Replica, a special edition motorcycle that celebrated the Grand Prix San Marino race won by Luca Reggiani Misano on August 30, 1987. The bike was sold in December 1987.
The AF1 Replica was basically the same elegant, sporty, and well-managed bike as its AF1 sister but was characterized by a more vibrant color than its sister model. Compared to the standard AF1, the replica version featured several modifications.
The AF1 Replica came with 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.
As for the standard features, the bike came dressed in a full fairing, a single seat with a pillion seat cover, a single exhaust system with a muffler on the left side, a single-sided swingarm, and three-spoke lightweight aluminum wheels.
As for power, the 1987 Aprilia AF1 125 Project 108 Replica had installed a 124cc two-stroke single-cylinder liquid-cooled engine underneath its clothes, boasting 29 hp with a peak force at 10,500 rpm and 18 Nm (13 lb-ft) torque at 10,000 rpm.
A six-speed manual transmission controlled by a wet multi-disc clutch handled the bike's power, sending it to the rear wheel via a final chain drive, launching the motorcycle to 169 kph (105 mph).
