KTM 150 SX 

The KTM 150 SX is a high-revving two-stroke motocross bike designed for riders who demand lightweight agility with a harder-hitting power delivery. Bridging the gap between the nimble 125 SX and larger-capacity models, it delivers a competitive edge for those seeking explosive acceleration and sharp handling in a race-ready package.
 Performance & Power Powered by a compact 143.99 cc single-cylinder, liquid-cooled two-stroke engine, the 150 SX features electronic fuel injection for precise throttle response and consistent performance across varying conditions. Its advanced power valve system ensures strong low-end torque while allowing the motor to scream through the rev range, making it ideal for aggressive corner exits and rapid straights. A close-ratio six-speed gearbox and Brembo hydraulic clutch provide slick, controlled shifts, while its lightweight engine design keeps overall mass to a minimum for razor-sharp manoeuvrability.
Control & Comfort The chassis is built from a lightweight central-cradle chromoly steel frame, delivering excellent torsional stiffness and rider feedback. Suspension duties are handled by 48 mm WP XACT AER front forks and a fully adjustable WP XACT rear shock, offering up to 300 mm of travel for tackling big jumps and rough terrain. High-performance Brembo disc brakes—260 mm at the front and 220 mm at the rear—deliver powerful, fade-free stopping, while the ergonomically designed seat and narrow bodywork allow unrestricted movement for confident control in any riding position.
Versatility & Style With aggressive Factory Racing-inspired graphics, the KTM 150 SX combines race-bred styling with functional design. Its slim bodywork, lightweight components, and optimised rider triangle make it perfectly suited for competitive track use, while modern features like electric start and handlebar-mounted map selection enhance convenience. Equally at home in intense motocross heats or training sessions, it offers a thrilling blend of style, performance, and adaptability for ambitious riders aiming to push their limits.
