Overview

Introducing the 2023 KTM 125 SX, a remarkable contender in the world of enduro-offroad motorcycles that expertly blends performance, agility, and cutting-edge technology. Priced at an MSRP of $7,949, this bike is designed for both aspiring riders and seasoned enthusiasts looking to conquer challenging terrains. KTM’s commitment to crafting lightweight and powerful machines is evident in the 125 SX, which embodies the spirit of off-road riding while offering an exhilarating experience on the trails. At the heart of the KTM 125 SX lies a spirited 124.8 ccm engine, delivering a robust 15.0 HP (10.9 kW). This power is harnessed through a slick 6-speed gearbox, allowing riders to seamlessly shift through gears while maintaining optimal control in diverse conditions. The innovative liquid cooling system ensures that the engine remains at peak performance even during the most demanding rides. With a bore and stroke of 54.0 x 54.5 mm, this bike exhibits exceptional throttle response and acceleration, making it perfect for navigating tight corners and steep inclines. Coupled with the lightweight chassis, at just 203.7 pounds, the 125 SX offers an impressive power-to-weight ratio of 0.1623 HP/kg, ensuring that every ride is both exhilarating and manageable. The 2023 KTM 125 SX is packed with advanced features designed to enhance rider confidence and comfort. Its central double-cradle-type frame constructed from 25CrMo4 steel provides a sturdy yet nimble foundation, while the WP XACT-USD fork and WP XACT Monoshock rear suspension deliver an impressive 310 mm of front travel and 300 mm of rear travel. This combination allows for superior handling on rough terrain, absorbing bumps and providing stability. The Brembo hydraulic clutch and powerful disc brakes — 260 mm at the front and 220 mm at the rear — offer precise control and stopping power, essential for any serious off-road adventure. With an electric starter and a sleek color scheme of white, orange, and grey, the KTM 125 SX not only performs exceptionally but also looks the part. **
