APRILIA RS 125 (2003-2004) Specs, Performance & Photos

The Aprilia RS 125 was a Grand Prix-derived, small displacement sports production replica made by Aprilia in 1992 to replace the Aprilia AF1. It was produced until 2010, when it was replaced by the Aprilia RS4 125.

In 2003, the Italian motorcycle maker released the Aprilia RS 125, a sports replica that packed the same technical, visual, and performance specifications as the previous one without changes.

Visually, the motorcycle had standard fittings, like a full fairing, a medium-sized windscreen, a two-piece dual seat, a single exhaust system with a silencer mounted on the left-hand side, and five-spoke alloy wheels.

Power-wise, the 2003 Aprilia RS 125 had its heartbeat set by a 124cc two-stroke single-cylinder liquid-cooled engine managed by a Dell'Orto carburetor, delivering an output power of 34 hp at 11,250 rpm and 20 Nm (15 lb-ft) torque at 10,000 rpm.

The engine was married to a six-speed manual transmission with a wet multi-disc clutch that sent the power to the rear end via a final chain drive, launching the motorcycle to a top speed of 171 kph (106 mph).

The riding experience was handled by a 40 mm inverted telescopic fork on the front with 120 mm of travel and a single shock absorber on the rear with 120 mm wheel travel.

As for the braking power, the bike's wheels were fitted with a 320 mm brake disc on the front tied to a four-piston caliper and a 240 mm brake disc on the rear squeezed by a dual-piston caliper, offering optimum stopping power.
