Features of the Aprilia SX and Aprilia RX125

The SX and RX125 share the same chassis and engine, but each has a distinct character that caters to different passions. The RX125 is focused on off-road riding and equipped to tackle any terrain or surface, while the SX125 is designed with supermotard style for street and track enjoyment. Both meet the expectations of aggressive motorcyclists seeking performance, style, and safety for everyday riding.

The Aprilia RX 125 is tailored for off-road enthusiasts, with full-size wheels (21-inch front, 18-inch rear) fitted with authentic block tires, delivering high performance and absolute control on any terrain. The

Aprilia SX 125, with its 17-inch wheels and sporty road tires, is one of the most exciting 50cc models available. It is agile, lightweight, and compliant with the latest Euro 5+ standards, delivering class-leading power for a truly enjoyable ride.

The water-cooled single-cylinder DOHC 4-valve engine meets the new EURO5+ regulations and boasts top-class performance with a maximum output of 15 HP (11 kW) at 10,500 rpm and a maximum torque of 11.5 Nm at 8,500 rpm.

New, more refined design

Aprilia has also been proactive in introducing unique and highly innovative designs to a number of entry-level models, including Supermotard and Enduro bikes. The new RX125 and SX125 have been given even more advanced styling, reflecting the latest trends in off-road motorcycles. Completely new body panels create a sleek, streamlined look that flows seamlessly from front to rear. The new matte black exhaust silencer is shorter, further emphasizing its light and nimble feel.

The frame, engine, swingarm, wheels, and tapered aluminum handlebars are all finished in high-quality gloss black, and the under-seat compartment can now accommodate a USB socket, sold separately.

Improved safety and practicality: New full LED lights and color digital meters

The new RX125 and SX125 are equipped with a new full LED lighting system and a color digital meter panel, upgrading the bike to advanced and practical equipment. The modern and easy-to-read meter screen features a beautiful rev counter in the center, with a scale that changes from white to red in a gradation pattern. It also displays a variety of riding information, such as gear position, two types of trip meters, maximum speed memory, average and current speed, riding time, average and instantaneous fuel consumption, etc.

Chassis

The RX125 and SX125’s advanced suspension and high-performance ABS braking system deliver precise, powerful braking for superior safety. Aprilia is the first in this segment to introduce Bosch ABS with anti-rollover mode. This ABS acts on the front wheel to precisely control braking and prevent rear wheel lift during hard braking.

The RX125 is equipped with wave discs, familiar from the racing world, measuring 260mm in the front and 220mm in the rear. The

SX125 features a large 300mm front disc with a two-piston floating caliper, and a 220mm disc at the rear, also with a floating caliper.

Both models are built around a sturdy steel dual-beam frame and large suspension components, with high-performance 41mm inverted forks providing 240mm of wheel travel. The rear suspension features a long swingarm for optimal traction, and a monoshock absorber with progressive linkage provides 210mm of travel.

Off-road bikes like the RX125 and SX125 demand high-quality components, especially wheels, which are crucial for both durability and light weight. The RX125 features high-quality wire spokes mated to blacked-out rims. The SX125 features wire-spoke wheels with 17-inch rims and wide sports tires (100/80-17-inch front, 130/70-17-inch rear) for excellent grip on asphalt surfaces. The

RX125 and SX125 are available in two new color variations: Cubozoa White, featuring a white body with purple graphics and red details, and Varanus Black, a black and red combination that reflects Aprilia Racing’s traditional color scheme.

New lineup of genuine accessories

The range of aprilia genuine accessories has been expanded to highlight the sporty appearance of the RX125 and SX125. These include red anodized aluminum brake and clutch levers that can be adjusted for optimal ergonomics, an aluminum brake fluid reservoir cap with the same finish, and anodized aluminum fork sliders that protect the front forks from scratches in the event of a fall.
