The Aprilia RX 125 was designed especially for the young drivers who are still working on refining their riding skills. The bike features Aprilia’s latest design language and is distinguished by an aggressive style and a pair of mean-looking 17 inch wheels wrapped in 110/70-17” and 150/60-17” tires.
At the heart of the Aprilia RX 125 lies a 125 cc single cylinder, two stroke engine which develops a maximum power of 16 kW and 16 Nm of torque at 9750 rpm.
The ride quality is assured by the double cradle frame combined with a front 40 mm upside down telescopic fork which offer a wheel travel of 260 mm and a rear long steel swing arm which offers a wheel travel of 260 mm.
As far as stopping power goes, the Aprilia RX 125 is fitted with front 260 mm and a rear 220 mm discs.

It was inevitable that the innovative SXV and RXV would extend their influence to other members of the Aprilia range sooner or later. The world-beating styling, performance and technology of these fantastic machines has engendered a family of eye-catching and modern off-road motorcycles. The SX 125 and RX 125 are the latest off-road machines from Aprilia. Specialist and refined, they are the obvious choice for young riders who want to stand out right from the very start. The SX and RX are both built to deliver total rider satisfaction. Though the technology is basically the same, it has been adapted to match the different specialities. The SX and RX share the same body, frame, engine and suspensions but have very different characters for very different passions.
With its 17” wheels and sports tyres, the SX is the obvious candidate for the prize of the meanest 125 over mixed routes. Nippy and lightweight, the SX delivers real ‘big bike’ performance without exceeding the power restrictions imposed by law. Its refined, sprightly engine never lets you down.
The RX and the SX 125 also share a clear Aprilia family look, obviously inspired by their bigger sisters, machines that have established a whole new trend in off-road design.
Aprilia was the first manufacturer to introduce dramatic innovations to the designs of essential enduro and motard motorcycles. In the same way in which the RXV and SXV have become style icons in their own right, the SX and RX are destined to leave their mark on young off-road riders.
As with all off road motorcycles worthy of respect, the SX and RX are built for maximum functionality and efficient riding and control. Their styling leaves no room for pointless frills and gadgets. The unmistakably pure lines of the SX and RX are simply unique among off-roaders.
The single cylinder unit that powers these Aprilia 125 cc motorcycles is a state-of-the-art two stroke engine. It is a classic example of how race-developed technology can deliver extremely low emissions as well as top performance. On the RX 125 and SX 125, Aprilia has succeeded in perfecting its two stroke design to bring it in line with the strict new Euro 3 standard without any loss of performance or riding satisfaction. This sparkling single cylinder engine easily develops the maximum permitted power for its class, with all the lightness and zippy acceleration typical of a high performance two stroke.
This engine has already established a place for itself in the hearts of 125 fans, thanks to its many advanced characteristics, including liquid cooling, and a balancer shaft. The cylinder has a nickel silicon carbide (Nikasil) liner for an ultra-reliable, extended life. Lubrication is provided by a separate mixer system.
Brakes and Suspension
Active safety on the Aprilia RX and SX is ensured by advanced suspension and a braking system that sets new standards for stopping power and progressive action. The front brakes feature a 260 mm disc and two-piston floating caliper while the back brake incorporates a 220 mm disc and another floating piston.
The robust, steel, double cradle frame is coupled to an over-sized suspension system. At the front is a mighty, 40 mm upside down telescopic fork offering wheel travel of 260 mm.
At the back, a long steel swingarm delivers maximum traction and a rear wheel travel of 270 mm.
Specialist motorcycles like the RX and SX demand top level components, especially wheels, the strength and lightness of which are so important to handling. The Aprilia RX and SX are equipped with prestigious spoked wheels with new black anodised rims. Just like top sports motards, the SX boasts lightweight 17 inch, wide profile wheels and generous sports tyres, 110/70-17” and 150/60-17” for maximum grip under all conditions.
To confirm its determination to build advanced motorcycles that are versatile and practical in everyday use, Aprilia has equipped the RX and SX with sophisticated digital instruments just like those on the bigger SXV and RXV.
Once again Aprilia motorcycles are going to feature in the dreams of young riders.
