Overview

Introducing the 2020 Hyosung RX 125, a spirited contender in the enduro-offroad motorcycle category that blends style, performance, and practicality into a compact package. Designed for both novice riders and seasoned enthusiasts, the RX 125 stands out with its agile handling and impressive features, making it an ideal choice for tackling varied terrains. With its striking black and red color options, this motorcycle is not only a functional tool for exploration but also a head-turner on the trails. At the heart of the RX 125 lies a peppy 124.20 ccm single-cylinder, four-stroke engine that delivers a respectable 15 HP at 10,500 RPM and a torque of 10.90 Nm at 8,250 RPM. This powertrain is expertly matched to a smooth 6-speed gearbox, providing a responsive riding experience that makes navigating through urban streets or off-road paths a delight. The liquid-cooled engine ensures consistent performance even during extended rides, while the advanced Magneti Marelli fuel injection system optimizes fuel efficiency and throttle response. With a compression ratio of 12.5:1 and a lightweight frame weighing just 120 kg (264.6 lbs), the RX 125 promises a lively and exhilarating ride. The RX 125 is packed with features that enhance both safety and comfort. Its double cradle steel frame is designed for maximum stability, complemented by a robust suspension system featuring a 41 mm telescopic upside-down fork at the front and a hydraulic monoshock absorber at the rear, offering impressive travel of 240 mm and 220 mm respectively. The braking system is equally noteworthy, equipped with a single disc and floating caliper setup on both the front (300 mm) and rear (220 mm) wheels, with the added safety of front wheel ABS for enhanced control in diverse riding conditions. The electric starter and comfortable seat height of 905 mm make it accessible for riders of various heights, allowing for a confident stance on all types of terrain. In summary, the 2020 Hyosung RX 125 is a well-rounded motorcycle that offers an exhilarating blend of performance, comfort, and safety technology, making it a solid choice for those looking to explore both urban landscapes and rugged trails alike.
