Overview
Introducing the 2017 KTM 125 SX, a standout contender in the world of cross-motocross motorcycles. Renowned for its lightweight construction and agile handling, the 125 SX is designed for both budding enthusiasts and seasoned riders looking to dominate the track. KTM has a storied legacy in off-road performance, and this model is a testament to the brand’s commitment to innovation and excellence. With its striking orange, white, and black color scheme, the 125 SX not only performs exceptionally but also turns heads on the track. At the heart of the KTM 125 SX lies a potent 124.80 ccm single-cylinder, two-stroke engine. This powerhouse is engineered for exhilarating acceleration and responsiveness, making it the perfect partner for tight corners and rough terrains. The 54.0 x 54.5 mm bore and stroke configuration, combined with the Mikuni TMX carburettor and Kokusan EMS ignition system, ensure smooth power delivery across the rev range. Riders will appreciate the 6-speed gearbox that provides precise gear shifts, allowing them to harness the full potential of the engine while maintaining control. Coupled with liquid cooling, the 125 SX can handle the rigors of intense competition without breaking a sweat, giving riders the confidence to push their limits. The chassis of the 125 SX is nothing short of revolutionary, featuring a chrome-molybdenum steel central-tube frame that promotes stability and durability. With a rake angle of 26.5°, the motorcycle is designed for nimble handling, while the WP-USD AER 48 front suspension and WP shock absorber with linkage offer an impressive 300 mm of travel at both the front and rear, soaking up the roughest terrains. The robust braking system, equipped with single discs and calipers on floating bearings, offers reliable stopping power, ensuring safety and control at high speeds. Lightweight at just 87.2 kg (192.2 pounds) with a ground clearance of 375 mm (14.8 inches), the 125 SX is built for maneuverability and precision, making it a top choice for motocross riders. **
