Introduction
Dedicated to today’s demanding young sports riders, the Aprilia RX and SX 125 incorporate many of the features that have contributed to the amazing success of the RXV and SXV. These two stylish, high performance motorcycles set new standards for the 125 market.
Early ’90’s Aprilia RX 125
RX is a historical name for Aprilia. Over the years the RX designation has graced machines with amazing performance, real ‘schools on wheels’ for young enthusiasts learning the ropes in off-road riding and racing. The new RX might not be an extreme enduro but it is perfectly able to tackle even the most challenging off-road circuits. The RX even has something of a split personality, because as soon as you get back on the road, it is equally happy as a daily commuter.
Exterior
Aprilia was the first manufacturer to introduce unique and dramatically innovative design to 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 also destined to leave their mark on young off-road riders. As with any self-respecting off-road machine, the design of these bikes is dedicated to total functionality, and efficient control. Their styling leaves no room for frills and gadgets. With their unmistakable lines, the SX and RX are simply unique among off-roaders.
The RX and the SX share a clear Aprilia family look, obviously inspired by their bigger sisters, machines that have established a whole new trend in off-road design.
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 was obviously destined to engender 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 from the crowd.
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 125 share the same body, frame, engine and suspensions but their characters suit very different passions.
The 125 cc single cylinder engine that provides the life and soul of these Aprilias is a state-of-the-art two stroke. 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.
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, trellis 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.
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, even when ridden to the limit on a racetrack.
At the back, the long steel swingarm used to obtain maximum traction is damped by a prestigious hydraulic monoshock with piggy back cylinder. Rear wheel travel is 270 mm.
Specialist machines like the RX and SX demand top quality components. The wheels, for example, are fundamentally important to this type of motorcycle, having to combine the contrasting properties of strength and lightness. The RX and SX are equipped with aluminium wheels. The RX is fitted with a classic enduro racing front wheel of 21” in diameter and a 90/90-21” tyre for fantastic grip on all sorts of surface. The 18” rear wheel is fitted with a 120/90 tyre, again in keeping with the best off-road traditions.
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.
Conclusion
These two models have definitely learned the lesson from their big sisters and what better conclusion than yet another example that confirms this fact. Aprilia has equipped the RX and SX with sophisticated digital instruments just like those on the bigger SXV and RXV.
Teenagers have two brand new models to dream about and we have also new test rides waiting so stay tuned!
