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 this bike 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.
Safety on the Aprilia RX is provided by advanced suspensions and a new top level braking system with front-wheel-only ABS that provides great power and modulability. Increased safety, better efficiency, Aprilia is the first to introduce the Bosch front-wheel-only ABS system with anti roll-over mode in this market segment, which, on the one hand provides precision and total control in braking and on the other adjusts the lifting of the rear wheel in the heaviest braking.
The RX 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 200 mm, connected to the frame and shock absorber with progressive linkage.
Specialist motorcycles like the 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.
Confirming its wish to build advanced motorcycles that are versatile and practical in everyday use, Aprilia has equipped the RX with sophisticated, compact, modern and easy to read digital instruments; in addition to the common functions, the digital dashboard also offers the travel diary, with the ability to view top speed, battery voltage, and with two trip mileometers indicating the distance travelled during riding sessions.
