Overview

Introducing the 2019 KTM 150 SX, a powerhouse in the cross-motocross category that combines lightweight agility with exceptional performance. This bike is crafted for those who crave the thrill of racing and the precision engineering that KTM is renowned for. With its vibrant orange, white, and black color scheme, the 150 SX stands out on the track and in the pits, embodying the spirit of competition and adventure that KTM is known for. Whether you’re a seasoned racer or an ambitious beginner, the 150 SX offers a perfect blend of power and control that elevates your riding experience. At the heart of the KTM 150 SX is a potent 143.90 ccm single-cylinder, two-stroke engine that delivers exhilarating acceleration and responsiveness. The engine features a bore and stroke of 58.0 x 54.5 mm, expertly tuned for an optimal powerband that keeps you in the race. With the Mikuni TMX carburettor and Kokusan EMS ignition system, riders can expect precise fuel delivery and ignition timing for an immediate throttle response. Coupled with a 6-speed gearbox and a multi-plate hydraulic clutch from Brembo, the 150 SX provides seamless power transitions, making it a joy to ride on both tight corners and open straights. Weighing in at just 87.2 kg (192.2 pounds), this bike is designed for agility, allowing riders to maneuver with confidence over rugged terrain. The engineering prowess of the 2019 KTM 150 SX extends beyond its engine. The robust 25CrMo4 steel central-tube frame ensures durability while maintaining a lightweight structure, contributing to its nimble handling characteristics. The WP-USD AER 48 front suspension and WP shock absorber in the rear provide an impressive 310 mm and 300 mm of travel, respectively, allowing riders to absorb bumps and jumps with ease. The braking system features a powerful single disc with four-piston calipers in the front and two-piston calipers in the rear, providing reliable stopping power when you need it most. With a ground clearance of 375 mm and an adjustable seat height of 950 mm, the 150 SX accommodates a wide range of rider preferences for optimal comfort and control. **

Pros

  • Lightweight and Agile: At 87.2 kg, the 150 SX offers exceptional handling and maneuverability, making it perfect for tight tracks and technical trails.
  • Powerful Engine Performance: The two-stroke engine delivers impressive acceleration and a responsive throttle, ideal for competitive racing and spirited rides.
