ALWAYS READY FOR OFF-ROAD FUN
A Euro 5+ compliant single-cylinder engine, long-travel suspension, wave brake discs, a 21” front wheel and an 18” rear wheel with knobby tyres leave no doubt that the RX 125 is built for adventure and ready to tackle any terrain. Rideable with an A1 licence, it is designed for young riders seeking the perfect balance between off-road performance and unmatched agility, even in an urban context.
Sports design
The design of the Aprilia RX 125 is sleek and minimalist, with sharp lines extending from front to rear, emphasising its racing DNA. The matte black exhaust seamlessly integrates with the glossy black frame, variable-section handlebar, engine and swingarm. The anodised glossy black wheels, sized for true off-road performance (21” front, 18” rear), combined with knobby tyres, ensure optimal control and traction on any terrain.
Ready to overcome any obstacle
The RX 125’s off-road spirit is reinforced by a top-tier chassis, designed to tackle even the most technical routes with agility. Its long-travel suspension offers 240 mm of travel at the front and 220 mm at the rear. The braking system features two wave discs—260 mm at the front and 220 mm at the rear—paired with single-channel ABS equipped with anti-rollover functionality. The engine is a modern, liquid-cooled, four-valve single-cylinder, optimised for strong acceleration and smooth power delivery.
Practical with a tech style
The Aprilia RX 125 is equipped with technology designed to enhance versatility and riding enjoyment in any situation. In addition to full-LED lighting, it features a colour digital display that provides all essential rider information. Rounding out the package is an underseat compartment set up to accommodate a USB charging port, available as an accessory.
