APRILIA SX AND RX 125

FOR YOUNG, SPORTY AND DEMANDING RIDERS, APRILIA SX AND RX 125 OFFER TOP LEVEL SPORTS CONTENTS. TWO HIGH PERFORMANCE BIKES WITH A STRONGLY DISTINCTIVE DESIGN

THE ONLY BIKES IN THIS SEGMENT TO SPORT AN ABS BRAKING SYSTEM

Heirs of Aprilia’s history of success in off-road competitions, the updated SX and RX 125s boast a sophisticated design, powerful performance and advanced technology that makes them bikes for people who want to stand out from the crowd right from the start of their two-wheel career.

The SX and RX offer great riding satisfaction to anyone climbing on-board. The same basic technology has been adapted to suit different tastes and needs: SX and RX have superstructure, frame, engine and suspensions in common, but each has a distinct character to suit different passions.

The wheels fitted with 17" sports tyres, make Aprilia SX one of the most effective 125s on mixed runs; nimble and lightweight, it provides the performance of larger engined supermotard bikes without exceeding the power limit of the class, partly due to its sophisticated and generous engine performance. All complemented by a line inspired by the Aprilia motorcycles that marked a new trend in off-road design.

Aprilia RX is perfect for off-road enthusiasts. The large 21” rims on the front and 18” on the rear shod with knobby tyres leave no doubts as to the objectives the RX sets for itself: rigorous performance and absolute control in any terrain conditions.

Design

Aprilia was the first to introduce a unique and highly innovative design on basic motorcycles like the motard and enduro . The SX and RX are destined to leave a mark in their segment with design at the service of functionality, where effective riding control is never sacrificed for fancy shapes or unnecessary trappings. Indeed, the unmistakable lines of these bikes make them truly unique in their segment. A distinctive trait of this revamped design can be found in the spoked wheels with black anodized rimsthe double-section black anodized aluminium handlebar and the handy engine guard.

The engine

The single cylinder 125 cc is the heart and soul of the new Aprilia. A modern engine, at the state of the art for four-stroke engines. A classic example of how technology developed in competitions can not only obtain benchmark performance but also make for extremely clean engines. With these bikes Aprilia has perfected the four-stroke engine to bring it in line with the strict Euro 4 standard without detracting from performance.

The brilliant lightweight single-cylinder engine easily reaches the maximum power ceiling for this displacement, with a thrillingly brilliant acceleration.

Chassis architecture

For impeccable safety, the ApriliaSX and RX boast advanced suspension and a new class-beating brake system with ABS, offering extraordinary, perfectly controllable stopping powerIncreased safety, better efficiency, Aprilia is the first to introduce the Bosch ABS system with anti roll-over mode that acts on the front wheel, guaranteeing precision and total control in braking on one hand and adjusts rear wheel lift in the most abrupt braking on the other. The SX’s 300 mm front disc with double piston floating calliper is assisted by a 220 mm rear, also with floating calliper. The RX instead comes with two beautiful wave discs, 260 mm front and 220 mm rear, clearly taken from the racing world.

The sturdy double cradle steel frame is coupled with oversized suspension: the powerful 41 mm upside down telescopic fork offering wheel travel of 240 mm.. At the rear, the long steel swingarm optimises traction, with a wheel travel of 220 mm, connected to the frame and shock absorber with progressive linkage.

Specialist motorcycles like the SX and RX also need high-level components, especially for the wheels, a key element for combining sturdiness and lightness. Aprilia RX uses prestigious spoked wheels with new anodised black hubs. Aprilia SX also adopts spoked wheels, 17 inches in this case, with wide channel and generously sized sports tyres - 100/80-17" and 130/70-17" - to provide maximum grip in any conditions.

Instrument panel

Confirming their commitment to building advanced motorcycles that are versatile and practical in everyday use, Aprilia has equipped the SX and RX with sophisticated, compact, modern and easy to read digital instruments; as well as offering more common functions. Its new features include the travel diary with the possibility of viewing top speedand two trip odometers showing the miles travelled during riding sessions.

Aprilia SX 125 is available in the new graphic variations Red Raceway and Silver Speedway, while the RX 125 will be available in Red Raceway.
