THE WORLD’S MOST PRESTIGIOUS HIGH PERFORMANCE 125 HAS JUST BEEN THOROUGHLY REDESIGNED TO KEEP IT BEYOND THE REACH OF THE COMPETITION. THE 2006 MODEL YEAR RS 125 IS NOW AN EVEN MEANER RACING MACHINE, AND RESEMBLES THE MIGHTY RSV 1000 R MORE CLOSELY THAN EVER. APRILIA RS 125, THE CHAMPION-MAKER The RS 125 is the undisputed leader among sports oriented 125 cc motorcycles. Aprilia has always led the field in lightweight sports bikes, pioneering new concepts and advanced solutions, and developing technology that others have had to struggle to follow. Like all Aprilia sports motorcycles, the RS 125 has benefited from the sophisticated technology that has been developed over years of success in GP racing, and quickly transferred into production. This technology has ensured the RS 125 a prestigious reputation among sports 125s. Competitive success has led to impressive sales results too: the RS 125 has been Europe’s best selling sports 125 for many years, and is the motorcycle most sought after by riders entering Sport Production racing. And rightly so, because when the competition gets tough, there is simply no other bike like the Aprilia RS 125. The 2006 Aprilia RS 125 is designed and built to maintain this technical supremacy. The new RS incorporates a whole series of technical improvements, and comes dressed in a fairing that is not only new in design and graphics, but shares a clear family resemblance to Aprilia’s flagship supersport, the RSV 1000 R. The Aprilia RS 125 gives young riders the best the market has to offer in terms of components and equipment, with a concentration of technical refinements that simply do not exist on any other 125. The following are just some of the main features of the MY 2006 Aprilia RS 125. · Sophisticated, tried and tested, Rotax two stroke engine, available in 11 kW and full power versions. · Super-rigid aluminium frame and swingarm derived from Aprilia’s vast GP experience. · New upside down fork. · New front brake with radial caliper and four opposed pistons. · New RSV 1000 R style fairing, windshield and tail. · New RSV Factory style, crossed spoke wheels. · New analog/digital instrument panel with multi-functional computer. · New RSV Factory style, forged steering yoke. · New oval section, racing silencer with riveted end plates. STYLE The mean, cutting edge look of the new RS 125 tells you that this is a professional racing machine. The styling of the RS is based on that of the RSV 1000 R and, as with all Aprilia sports bikes, is the result of painstaking aerodynamic research. The new fairing, for example, was perfected by extensive wind tunnel testing, to guarantee GP class wind protection and minimum drag, and to obtain maximum racetrack efficiency from the small engine. The fairing, windshield and tail not only look mean and aggressive, but allow the RS 125 to reach a blistering top speed, eliminating the turbulence that can disturb rider concentration. Man and machine really can become one when the machine in question is an Aprilia RS 125. The latest generation twin halogen headlight also adds to the mean look of the new RS, and delivers a high power light beam for enhanced visibility and safety at night. The sleek tail also houses a new light cluster with a pure racing look. In fact, a great deal of effort has been put into all aspects of design of the RS 125 tail. As a result, the passenger seat integrates perfectly with the silhouette of the bike. Because the new, crossed spoke wheel design is lighter, more reliable and safer, it also improves sports performance. ENGINE The powerful but reliable, single cylinder, two stroke, Rotax-Aprilia engine needs no introduction. Over the years it has won a reputation for being unbeatable on the track and dependable on the road. Still today, this engine boasts technical solutions that are state-of-the-art for two strokes, including a crankcase reed valve intake, liquid cooling, an anti-vibration balancer shaft, and an automatic mixing system. The RS 125’s engine has been constantly updated over the years to keep in line with the latest emission control legislation without penalising performance. A catalytic converter and precision carburation enable Aprilia’s single cylinder two stroke to sail through homologation to Euro 2 standards. And the amazing thing is that this has been achieved without losing out on performance: in fact the engine that powers the Aprilia RS 125 remains the reference point for all 125 cc engines in terms of sheer power. CHASSIS Without a doubt, the most advanced single component on the RS 125 is its frame. Developed from Aprilia’s vast experience in GP 125 racing, the RS 125 frame is made from cast aluminium alloy with cross-ribbing reinforcement. Despite its extremely light weight, this advanced structure achieves amazing torsional rigidity, setting the standards for Aprilia’s competitors. The box section, aluminium alloy swingarm has the highest torsional rigidity of all production 125 cc swingarms. Its asymmetric design enables the exhaust to pass extremely close to the body of the motorcycle, enabling more acute angles of lean to be achieved on bends without risking dangerous contact with the asphalt. The suspension too plays a fundamental role in ensuring not only the RS 125’s performance, but its safety and comfort too. The 2006 RS 125 boasts better suspension than ever before. The upside-down fork has been thoroughly redesigned for maximum performance on the racetrack while also delivering a more satisfying ride on public roads. The rear suspension features rising rate linkages based on Aprilia’s racing technology, for excellent traction and superb comfort even over uneven road surfaces. The hydraulic monoshock that provides the damping for the swingarm is also adjustable in spring preload. BRAKES Like any self-respecting supersport motorcycle, the RS 125 has to have the best when it comes to components. The braking system is brand new, and designed for maximum efficiency under competitive riding conditions. The front brakes use a radial caliper with four opposed pistons, in keeping with the latest trends in racing technology. In addition to the 320 mm front disc, the system also incorporates a radial master cylinder and aeronautical hoses for maximum precision and unrivalled braking power. The rear disc is 220 mm in diameter and is also equipped with metal braided hoses for perfectly balanced braking under difficult race conditions. EQUIPMENT The world’s top racing 125 obviously deserves top quality equipment. In addition to a high-tech chassis, the Aprilia RS 125 benefits from the most prestigious components available. The compact and lightweight, latest generation instruments are derived from those of the RSV 1000 R and include an analog rev counter and a multifunctional digital display incorporating an on-board computer that can be operated directly from the handlebars. To keep everything under control, the instrumentation includes a speedometer, rev counter, coolant temperature gauge and a racing chronometer. The system even has provision for interfacing with an optical alignment device for racetrack use. COLOUR SCHEMES The new Aprilia RS 125 is available in a choice of two colour schemes, all of which emphasise its mean, aggressive nature. Classical Aprilia Black is now joined by a GP Aprilia White version, that gives the RS 125 a mix of sporty good looks and Italian elegance, just like its big sister, the RSV 1000 R. POWER KIT A power kit, designed exclusively for racetrack use, is also available as an optional accessory to achieve the full potential of this amazing two-stroke engine. The kit includes: - expansion chamber racing exhaust - complete racing exhaust valve - control unit and solenoid for racing exhaust valve - needle, main jet and atomiser for full power carburation - racing spark plug THE RS 125 TO STAR IN THE Junior GP Racing dream Aprilia has always been intent on helping young riders develop their skills. In the past, this involvement led to the RS 125 Challenge, one of the most prestigious single marque trophies, and the competition in which most of the Italian riders now competing at world championship level learned their trade. In 2006 Aprilia will again be taking the lead in promoting motorcycling among the younger generation of riders. Aprilia is organising a prestigious new competition to give youngsters the chance to show their true colours with a minimum of expenditure. The protagonist, of course, will be the Aprilia RS 125, suitably prepared in a special Cup version. More than capable of delivering thrilling racetrack performance, the RS 125 will be the perfect machine for developing the talents of tomorrow’s champions. Junior GP Racing Dream is an initiative of Aprilia in conjunction with FMI (the Italian Motorcycling Federation), and weekly motor sports magazine Motosprint. The competition’s primary objective is to select a number of promising young riders and offer them the chance to enter the world of GP racing. Aprilia’s aim is clear: to keep alive the great racing tradition that has led to Italian riders dominating the world GP scene. The new competition is dedicated to boys and girls between the ages of 13 and 16 who dream of a career in motorcycle racing and who accept to take part in the selection process that leads up to the competition. Main stages of the competition: • Initial selection will be held late in 2005, and will be free of charge for all those who enter by filling in the application form published in Motosprint. • The single marque challenge trophy will be held in 2006, using “Junior GP” version Aprilia RS 125s. Participation will be restricted to the 36 riders picked during initial selection. • The winner of the single marque trophy will be entered free of charge in the 2007 Italian GP Championship as a member of a team racing Aprilia 125 GPs. The basic requirements for the Junior GP Racing Dream competition are as follows: • The competition is open to boys and girls born in the years 1993, 1992, 1991, and 1990. • The 2006 single marque challenge will be spread over 5 races. • A junior GP class FMI licence is required to participate in the 2006 challenge. • Selected riders will be issued with an FMI licence free of charge. The entry fee for the Junior GP is euro 6,000. For this fee, selected riders will receive: • An Aprilia 125 RS ”Junior GP” for use in all official trials, to be supplied by Aprilia before the race and to be returned to Aprilia after the race. This applies to all the races in the 2006 challenge calendar. Lots will be drawn to determine the allocation of individual motorcycles to individual riders. • Race preparation and assistance. • Transport of the motorcycle to and from the circuit. • Spare parts, tyres, fuel and oil. •Leathers, helmet, gloves, and boots (participants must wear the protective clothing provided by the organisers). At the end of the season, all material in use at the time (including the motorcycle used for the last race), will become the property of the rider. At the end of 2006, further selection will take place to find another group of candidates for the 2007 Junior GP.
