With the ergonomics of a super sporty bike, an aluminium frame, finely-tuned engine and the best of new technology all wrapped up in a dynamic, aggressive look, the new RS 125 embodies the Aprilia passion for outstanding performance, finished with details and refinements that make it a brilliant choice for new riders and experienced champions alike.

A chassis that sets the benchmark

Drawing on decades of track experience and success, the Aprilia Racing Team have designed an aluminium frame that is a world first. Constructed from diecast beams with crossed reinforcement ribs, the RS 125's lightweight yet robust structure delivers outstanding handling and stability both on the road and track. The upside-down fork and single shock secured to the asymmetrical swingarm add the final flourishes to a chassis that is, in short, simply stunning.

Power and respect for the environment

The technological heart of the Aprilia RS 125 is a 4-valve distribution, liquid-cooled single cylinder with completely revamped thermodynamics. It delivers a more robust torque curve, with maximum power reached at lower revs, meaning reduced fuel consumption. The new engine is Euro 5-compliant, for outstanding performance that doesn’t come at the cost of the environment.

Ergonomics and digital display

The Aprilia RS 125 promises a riding position that is truly sporty, with no compromises, no shortcuts taken. The foot pegs are designed to avoid fatigue, the handlebar is placed so that the rider has total control of the bike, with the clip-ons raised by 18 mm for greater comfort. The Aprilia RS 125 also sports a new digital instrument display, packed with data such as fuel level indicator, instantaneous and average fuel consumption, remaining mileage and much more.

2021 colours:

Aprilia Black and Sintesi Blue

A replica in name, original at heart

The Aprilia RS 125’s new look is inspired by the latest RS 660 and Tuono 660, with their modern, aggressive and highly original appearance, emphasised by the triple headlight and stunning aluminium frame that are a nod to the world of racing. The RS 125 is also available in a GP Replica version with a livery that evokes the Aprilia MotoGP RS-GP, Quick Shift electronic gear change and a passenger seat cover.
