NEW RS 125, THE SCHOOL OF CHAMPIONS
 

Aprilia's know-how and technology have always led the way in the world of 125 supersports. Aprilia has regularly topped the sales tables with bikes that inspire young riders with the passion not only to dream, but to compete. The machine that symbolises Aprilia's supremacy in the 125 market is now back, completely renewed in style and technology. The latest RS 125 is more supersport than ever, and is not going to be beaten easily. It has all the cutting edge technology, style solutions and aerodynamics of a real GP racer, and is totally unrivalled when it comes to developing your passion and skill, on the road and on the track. The new RS 125 is today's bike for tomorrow's champions.
 
NEW RS 125, RACING TECHNOLOGY
 
1. POWER AND RELIABILITY
The liquid cooled, single cylinder, two-stroke RS125 is the technical reference point for all other 125 cc supersports. Derived directly from Aprilia's experience on the world's GP racetracks, the RS 125 is totally reliable on the road and aggressively powerful on the track, thanks to advanced technology like crankcase reed valve induction and a vibration damping counter-shaft. The RS 125 is even homologated to Euro 2 standards, because performance and respect for the environment really can go hand in hand.
 
2. RACE-WINNING AGILITY
The RS 125's sophisticated and lightweight frame is developed from the superb racing frames of Aprilia's amazing 125 GP bikes. It is made from polished aluminium alloy, guarantees extremely high torsional rigidity, and delivers maximum control and agility under racing conditions.
 
3. COMFORT AND SAFETY
The upside down fork has been completely re-designed, as has the rising rate rear suspension. The result is performance, safety, and an impressive level of comfort in daily commuting as in racetrack use. The brakes are completely new too and represent the pinnacle of world production. At the front, the RS 125 boasts a four-piston, radial caliper front brake with aeronautical metal braided brake hose and a 320 mm floating disc. The 220 mm rear disc unit also features aeronautical metal braided hose for precise, balanced and powerful, GP style braking.
 
4. RACING WHEELS
The ‘Y' spoke alloy wheels have six spokes at the front and five at the rear. These low weight, high strength wheels are fitted with tubeless radial tyres for unrivalled agility with guaranteed road-holding under all conditions.
 
5. GP SWINGARM
One of the most prestige components on the new RS 125 is its die-cast aluminium alloy swingarm. In addition to guaranteeing the highest degree of torsional rigidity of any production 125, the swingarm's special design also lets you lean further than ever without touching the asphalt.
 
6. ADVANCED AERODYNAMICS
Aggressive, streamlined, and breathtakingly beautiful, the new RS 125 is born to win. Its styling is the result of advanced research into aerodynamics and extensive wind tunnel testing. It should come as no surprise, therefore, that the RS 125 affords excellent wind protection, and minimum air resistance. Everything about it is made for speed, from the latest generation, twin headlight nose fairing to the tail, with its aggressive, streamlined, integrated seat and powerful rear light cluster.
 
7. RACING INSTRUMENTATION
The compact and lightweight new instruments incorporate all the functions of a real racing unit, including an analog rev counter and a multi-functional digital display with handlebar controls to operate the tachometer, trip counter, battery voltage meter, clock and 20 lap timer, coolant temperature gauge and fuel reserve indicator.

EUROPE'S TOP SPORTS 125: WORLD CHAMPIONSHIP TECHNOLOGY IN A PRODUCTION MOTORCYCLE.
 
APRILIA RS 125
 
Aggressive, decisive, and with plenty of character to express its dynamic, lightweight nature in a personal, unique style that typifies Italian passion for motorcycle racing. For years the RS 125 has been unbeaten on the 125 Sport Production racing circuit.
The RS 125 comes in two versions, Poggiali Replica and Aprilia Black, both destined to reinforce the market leadership of the RS 125, Europe's best selling road sports bike.
The Aprilia RS 125 brings the under 18 rider the best the European motorcycle market has to offer in terms of equipment and technology.
The sporty lines of this bike are the result of painstaking design and advanced aerodynamic research. Fruit of extensive wind tunnel testing, the aerodynamic form ensures total protection and minimum air resistance, giving a whole series of advantages including reduced fuel consumption and optimised performance under all conditions.
The aerodynamic fairing and windshield, with integrated hand guards to eliminate all turbulence, allow the rider to really make the most of the incredible speed and performance of this bike. The styling of the front mudguard matches the rest of the bodywork. The RS 125 is proof that perfect aerodynamics mean stability and safety at high speed.
The headlight cluster features a multi-focal double lamp unit and gives the bike an original, eye-catching appearance. Naturally, as well as looking good, the headlight cluster also adds to active safety during night-time riding and guarantees instant visibility in the day.
The tail not only improves aerodynamic penetration but also incorporates a spacious lockable storage compartment to house items like locks and rainproofs.
The passenger seat is integrated in the tail to avoid spoiling the clean, streamlined lines of the bike. The tail is mounted on an extremely lightweight rear frame.
The fuel tank has a capacity of 14 litres, and gives exceptional autonomy. Not only, but its perfect shape allows the rider to hug the bike like a leech.
The five spoke wheels look sporty but are also lightweight, reliable and safe. The competition standard braking system features a 320 mm front disk with a four piston calliper, and a 220 mm diameter rear disk.
The suspensions play a fundamental role in ensuring top level performance, safety and comfort. The Aprilia RS 125 is equipped with a 40 mm Ø upside down hydraulic action telescopic fork, with wheel travel of 120 mm. The front fork is one of the winning cards taken from the Aprilia 125 Challenge Trophy.
The rear suspension's hydraulic monoshock has also been developed on the basis of racing experience and features adjustable preload too.

The aluminium alloy perimeter beam frame gives exceptional torsional rigidity and light weight. Its design is the reference point for all our competitors. Here again, the transfer of knowledge and technology from the track to the road is typical of Aprilia's approach to quality, technology and safety.
Extensive wind tunnel testing has led to a globally improved CX for this already aerodynamic motorcycle, and has optimised even further the performance of its 125 cc two stroke engine. This advanced power unit features water cooling, balancing countershaft, exhaust control valve and reed intake for riding pleasure and constant power.
The aluminium silencer complements the bike's styling and is highly efficient in maximising engine power and minimising noise.
RS 125 is equipped with a catalytic exhaust in compliance with EURO 2 specifications.
This sporting Aprilia is available in two versions: the RS 125 for newly licensed riders with power limited to 11 kW and the RS 125 kat Euro 2 full power. A conversion kit can be fitted to the 11 kW version to convert it to full power at a later stage.
The side stand safety system is another extremely important feature. A safety switch prevents the bike being started up and ridden off with the stand down.
The racing style instruments not only look good but are also easy to read. The dashboard includes speedometer, rev counter and coolant temperature gauge to allow the rider to keep all important parameters under control. The speedometer can be removed quickly and easily for track use.
