VEHICLE REVIEW

2009 Aprilia RS125 ( Aprilia puts enthusiasts on track with new RS 125 )

Lap for lap, dollar for dollar, this GP-bred track bike outclasses larger displacement alternatives. With the debut of Aprilia’s track-only RS 125 two-stroke single, outsmarting the big bore boys has just become a sport in itself. The Italian manufacturer’s major-thrills track bike with the amazingly low price point is an all-new option for enthusiasts who want the speed, agility and superior handling that only a super-light-weight motorcycle can deliver. Add an Aprilia Racing-inspired, world-championship-bred 125cc engine, superb brakes, spot-on gearing, sizzling Italian styling and the low MSRP of just $5499 and the Aprilia RS 125 becomes the stealth track bike of choice.
As the leading manufacturer in 125cc and 250cc MotoGP competition, Aprilia has perfected the art of engineering championship-winning smaller-displacement race bikes. That expertise, along with Aprilia’s characteristically high level of premium components, makes the new RS 125 the best possible value for enthusiasts who take their track time serious – but who don’t want to sacrifice fun. As increasing numbers of motorcycle enthusiasts discover the challenge and thrill of honing riding skills on a closed circuit during a group track day or weekend, today’s 600 to 1000cc sport bikes with their huge horsepower and top speed numbers aren’t always the best choice. A smaller displacement machine actually helps to create a better, more confident rider because it requires more input and concentration to score good lap times. At the same time, it allows the rider to really push it to the limit while big displacement bikes often don’t inspire the same level of confidence.

Engineered for the Ultimate On-Tack Experience
At the heart of the RS 125 is a sophisticated single-cylinder two-stroke, liquid-cooled engine, based on the same race-proven technology that has resulted in a continuous string of competition victories for Aprilia Racing. Able to reach triple digit speeds, the power plant is packed with technical advancements including a crankcase reed valve intake, anti-vibration balance shaft and an automatic fuel-oil mixing system. A robust 6-speed transmission delivers the power to the rear wheel with ratios designed to suit a variety of race track configurations. The RS 125 is fitted with high-performance, race-style, upside-down front forks and a hydraulic rear mono shock mounted in a rising rate linkage, designed to work in concert to deliver the highest degree of race track compliance. Torsional rigidity is excellent, again thanks to the bike’s development on the world’s toughest race tracks. The RS 125’s lightweight polished cast aluminium twin spar frame is reinforced with cross ribbing for additional strength while the advanced chassis is mated to a box section, aluminium alloy swing arm. Styled after its championship-winning GP racing siblings, the RS 125 features a distinctive fairing and tail section that has been wind tunnel tested to deliver minimum drag. Riders benefit from improved top speed when tucked in behind the windscreen on long straights. The sleekly aerodynamic bodywork signals that the RS 125 would rather be in motion than standing still.The RS 125 is the undisputed leader among 125 cc super sports. 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. Over the years, the RS 125 has forged a reputation as the standard setter for sports 125’s. Sales success has come naturally too, with the RS 125 topping the sales tables on all European markets. The RS 125 is the inevitable choice of 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 2009 Aprilia RS 125 is designed and built for technical supremacy and has the looks to match. Its graphics are totally new and based entirely on those of the bike that dominated the 2006 250 GP world championship. 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 are not found on many super bikes.

OVERVIEW SPECIFICATIONS

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 carbonation has won Aprilia’s single cylinder two stroke homologation to Euro 3 standards. And the amazing thing is that this has been achieved without losing out on performance: the Aprilia RS 125 engine remains the reference point for all 125 cc power plants.

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 swing arm has the highest torsional rigidity of all production 125 cc swing arms. Differential side members enable the exhaust to follow a path that maximises engine performance and enables 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 2009 RS 125 can rely on an upside-down fork that has been optimised 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 125 GP racing technology, for excellent traction and superb comfort even over uneven road surfaces. The hydraulic mono shock that provides the damping for the swing arm is also adjustable in spring preload.

BRAKES

Like any self-respecting super sport 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 brake is a genuine state-of-the-art, high performance system with a radial caliper and four opposed pistons. 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, high performance braking.
