Now in stock - call us now to reserve!


A very distinctive motorcycle with high level performance and design. The only bike in this segment to sport a front-wheel-only ABS braking system. Heir of Aprilia’s history of success in off-road competitions, the updated SX 125 boasts a sophisticated design, powerful performance and advanced technology that makes this bike for people who want to stand out from the crowd right from the start of their two-wheel career. The SX offers great riding satisfaction to anyone climbing on-board.

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 SX 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 SX’s 300 mm front disc with double piston floating calliper is assisted by a 220 mm rear, also with floating calliper.
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 SX also need high-level components, especially for the wheels, a key element for combining sturdiness and lightness. Aprilia SX adopts 17-inch spoked wheels with wide channel and generously sized sports tyres - 100/80-17" and 130/70-17" - to provide maximum grip in any conditions.


Confirming its wish to build advanced motorcycles that are versatile and practical in everyday use, Aprilia has equipped the SX 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.
