2006 Aprilia RS 50

Aprilia RS 50

Eye-catching competition style: the Aprilia RS 50 knows no compromise. This 50 cc sports bike was conceived to combine riding pleasure and lively performance.

The Aprilia RS 50 looks and performs like a racer. And its engine, chassis and aerodynamic design give it a real cutting edge. The look of the RS 50 is dominated by its wrap-around fairing, designed and tested in a wind tunnel. The front fairing with integrated hand guards provide total rider protection, eliminate turbulence and ensure optimum aerodynamic penetration. Thanks to its excellent CX, the RS 50 is capable of an impressive top speed despite its small engine size.

The double 35 Watt headlight cluster contributes to the bike's aggressive racing look, provides excellent lighting and makes a major contribution to road safety. The plastic headlight shield reduces weight over the front forks and gives significant advantages in terms of riding precision. The front mudguard blends perfectly with the fairing, and enhances the Aprilia RS 50's streamlined looks.

The characteristic aerodynamic tail completes the Aprilia RS 50's racing image and also houses a spacious lockable storage compartment, ideal for carrying wheel locks and rainproofs. The tail also comprises the passenger seat, for use in countries where passengers can be legally carried. The passenger seat does not spoil the pure racing image nor does it interfere with the bike's aerodynamics.

Thanks to the Aprilia RS 50's low fuel consumption, the 13 litre fuel tank gives incredible autonomy. The tank also emphasises the bike's competition styling, sitting as it does right on top of the twin-spar frame just like on a real GP racer.

The RS 50's bodywork does not hide the fantastic die cast aluminium frame - a true Aprilia masterpiece. The Aprilia RS 50 is the first production 50 cc motorcycle to be equipped with this type of high technology frame that combines light weight and unbeatable structural strength.

The stylish and effective double member swing-arm optimises the action of the hydraulic monoshock. Wheel travel is 120 mm. At the front end, the hydraulic action telescopic fork delivers reliable, safe, sports performance, with smooth riding and effective damping even on rough road surfaces. The 35 mm fork inners permit wheel travel of 110 mm and absorb all the stopping power the RS 50's powerful braking system can deliver.

The front brakes deliver powerful, safe braking that sets a whole new standard in stopping power. The stainless steel disk is an impressive 280 mm in diameter and the calliper is a double piston unit. The rear brakes are of the same high standard, thanks to a 220 mm diameter stainless steel disk and powerful single piston calliper with aluminium mounting bracket.

The light alloy wheels with five swept spokes are another eye-catching feature of the Aprilia RS 50. The wheel diameter of 17", like on bigger super sports machines, keeps weight down and improves manoeuvrability. A chassis of this high standard deserves a top class, high technology engine. The RS 50 uses a liquid cooled single cylinder two stroke, with reed intake and balancing countershaft. Separate mixing lubrication is provided by a variable displacement volumetric pump. An electric starter also makes the bike easy to use for daily travel.

The six speed gearbox makes the most of the engine's high power and a large, easy to read rev counter makes it easy to change gear at just the right engine speed.

Finally, add a whole range of important details that are normally only found on bigger bikes. These include forged aluminium gear and brake levers, die cast aluminium footrest mounts, an aluminium silencer, and tubeless radial tyres.

Under its racing skin the Aprilia RS 50's exhaust hides the same respect for nature that you can find on all Aprilia motorcycles. The catalytic exhaust complies with EURO 2 specifications without penalising performance.
