APRILIA RS4 125 (2014-2015) 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.

It started as the Aprilia RS 125 Extrema and was made until 1996 when the maker dropped the "extrema" designation. Over its production period, the bike had several revisions, like the one in 1996, 1999, and 2006. The RS 125 was dropped in 2012 in favor of the new RS4 125 model.

In 2014, the Italian motorcycle manufacturer released the Aprilia RS4 125, a small-displacement motorcycle in its third consecutive production year. It packed the same characteristics as the previous one without modifications.

The bike's visual department was characterized by standard fittings, like 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.

Some notable features of the 2014 RS4 125 included the new four-stroke Rotax engine, a super rigid aluminum frame and swingarm derived from Aprilia's GP program, RSV 1000 R-styled fairing, windscreen, and tail, and RSV Factory-styled crossed spoke alloy wheels.

As for the power figures, the 2014 Aprilia RS4 125 had its heartbeat set by a 124cc four-stroke single-cylinder liquid-cooled engine that delivered an output power of 16 hp at 10,500 rpm and 11 Nm (8 lb-ft) torque at 8,500 rpm.
