Introducing the 2020 KTM 150 SX, a true gem in the cross-motocross segment designed for riders who crave agility and precision on the track. As a part of KTM's acclaimed SX lineup, this lightweight powerhouse caters to both amateur and experienced riders looking for a competitive edge. With its impressive blend of power, handling, and cutting-edge technology, the 150 SX stands out as a preferred choice for those eager to conquer dirt trails and motocross tracks alike. At the heart of the 2020 KTM 150 SX is a robust 143.99 cc single-cylinder, two-stroke engine that delivers exhilarating performance. The Mikuni TMX carburettor ensures crisp throttle response, while the Kokusan EMS ignition system optimizes power delivery across the rev range. Riders will appreciate the seamless 6-speed gearbox, which allows for quick gear changes, enabling them to tackle various terrains with confidence. The liquid cooling system keeps the engine at optimal temperatures, ensuring consistent performance during long rides. With a dry weight of just 87.5 kg (192.9 pounds), the bike is incredibly nimble, allowing for precise maneuvering that inspires confidence when tackling sharp corners or jumping obstacles. The KTM 150 SX is equipped with advanced suspension technology designed to enhance the riding experience. The WP-USD AER 48 front forks and WP shock absorber with linkage provide impressive travel—310 mm at the front and 300 mm at the rear—ensuring that riders can absorb bumps and jumps effortlessly. The lightweight 25CrMo4 steel frame contributes to the bike's agility and stiffness, resulting in superior handling characteristics. Furthermore, the powerful braking system, consisting of a 260 mm front disc with four-piston calipers and a 220 mm rear disc with two-piston calipers, guarantees responsive stopping power, giving riders complete control in any situation. The adjustable seat height of 950 mm (37.4 inches) accommodates various rider heights, enhancing comfort and control. **
