For many years the Aprilia RS 125 has been, and is still the point of reference for sport bikes dedicated to younger riders, a combination of content and style, ready for the best performance on the road and on the track.

Born out of Aprilia's racing pedigree, aggressive, capable of expressing dynamic character and light weight in a personal and recognisable style, RS 125 MY2017 highlights Aprilia's passion for sport with a level of technological refinements worthy of a true Superbike.


Exclusive ergonomics of a true super sport bike, sleek fairing, aluminium frame, a generous engine and the best components and technical features in a look that is now even closer to that of the RSV4 superbike.

The beating heart of the Aprilia RS 125 is a modern and technological 125 cc single-cylinder, 4-Stroke, 4-Valve electronic injection engine with liquid cooling: reliable on the road and powerful on the track, it has particularly refined technologies such as double overhead camshaft timing (DOHC).


With ultra-modern conception and design, lightweight and compact, it has allowed development of a refined chassis. Its power, optimally calibrated, guarantees responsiveness even at low revs. Vibrations are reduced to the minimum by a balancing countershaft. Euro 4 approved, it guarantees environmentally-friendly top performance.

The 2017 MY RS 125 is installation-ready for Quick Shift, the innovative gear shifting system that Aprilia has used and perfected on tracks all over the world. Just like with its big sister, the RSV4, the electronic system manages torque interruption for the engaged gear change, how far the throttle is open and the engine revs, allowing the rider to upshift while holding the throttle open and without using the clutch.

The exhaust, which is unmistakably racing inspired, is completely integrated within the lower part of the fairing. A solution with a strong aesthetic impact that effects the dynamic performance of the vehicle, based on the centralisation of the masses.

Developed on the basis of Aprilia's experience on the track, the spectacular perimeter frame consists of die cast aluminium spars with crossed reinforcement ribs. It is a lightweight structure, capable of providing high torsional rigidity in order to guarantee top performance on the road and on the track.

The solid upside-down fork and the rear suspension with racing-derived monoshock secured to the asymmetrical swing arm ensure performance, top level safety and comfort.


The split 6-spoke design of the wheels emphasises the purposeful character of the RS 125. A configuration that is once again merit of racing experience that ensures light weight and speed going into corners. The braking system uses a four-piston radial caliper on the front wheel, assisted by Bosch single-channel ABS, that grips a 300 mm diameter steel disc. The rear mounts a single-piston caliper that grips a 220 mm disc and has a tone wheel to guarantee anti roll over protection. Maximum performance and safety at every braking point. The license plate mount and turn indicators can be easily removed for track use.

Compact and ultra-lightweight, the new instrument cluster provides all the functions of true racing instrumentation: from the analogue Rev. counter to the multi-function digital display with handlebar controls for the speedometer, trip master, battery voltage, time and stopwatch with memory for 20 laps, cooling circuit temperature indicator and fuel reserve indicator, OBD warning light and ABS fault warning light. The AMP ECU that enables connectivity between the bike and your smartphone is also available as an accessory.
