APRILIA RS4 125 (2012-2013) Specs, Performance & Photos

In 2012, the Italian motorcycle maker released the Aprilia RS4 125, a sports-oriented entry-level motorcycle in its first production year, which replaced the previous Aprilia RS 125. The 2012 model packed a four-stroke single-cylinder fuel-injected engine instead of the previous two-stroke carburated one.

The bike had standard features, such as a full fairing with a dual headlight system, a small windscreen, a two-piece dual seat, a single exhaust system with a silencer mounted on the right-hand side, and multi-spoke alloy wheels.

In the power department, the 2012 Aprilia RS4 125 had installed a 124cc four-stroke liquid-cooled single-cylinder engine that delivered an output power of 16 hp with a peak force at 10,500 rpm and 11 Nm (8 lb-ft) torque at 8,500 rpm.

The power generated by the engine was controlled by a six-speed transmission with a wet multi-disc clutch and sent to the rear end via a final chain drive.

Suspension-wise, the motorcycle packed a 41 mm inverted telescopic fork on the front with 110 mm of travel and a single shock absorber on the rear with 130 mm of travel, providing optimum suspension performance and handling capabilities.

As for the stopping power, the bike's wheels were fitted with a 300 mm brake disc tied to a four-piston caliper on the front and a 218 mm brake disc on the front coupled to a single-piston caliper.
