The 2026 KTM 65 SX is more than a youth motocross bike its a race-ready machine built to help the next generation of champions reach their potential.

The 2025 KTM 65 SX stands out with a compact, purpose-built powerplant: a single-cylinder, 2-stroke engine delivering 64.9 cm displacement, paired with a six-speed transmission and a chain primary drive. Its light, race-ready chassis, built from chrome-molybdenum steel in a central-tube frame, rides on spoked wheels with aluminium rims for precise handling and responsive feedback. The ride is anchored by a front XACT 35 WP Upside-Down fork with a 35 mm diameter and 215 mm of travel, plus a matching XACT WP mono shock at the rear providing 253.5 mm of travel for confident off-road progression. Viewers will notice the compact stance, aided by a dry weight of 53.5 kg and a seat height of 730 mm.

Capability and control come through thoughtful spec details: a front brake diameter of 198 mm and a rear brake diameter of 180 mm, both disc brakes, with a 4.5 liter fuel tank to balance feats of agility and range. The 1142 mm wheelbase gives stability on tricky terrain, while a minimum ground clearance of 259 mm helps clear obstacles. The front handlebar setup uses aluminium bars with a diameter of 28/22 mm for precise steering input, and the steering head angle sits at 64.5 degrees to support quick, confident direction changes. The engines bore measures 45 mm and stroke 40.8 mm, tuned for punchy mid-range performance that suits riders who crave immediate engagement.

Durable construction and everyday practicality are evident in the steel rear subframe and the overall build quality. The front brake type is a disc, as is the rear brake type, ensuring dependable stopping power in varied terrain. The fuel system, cooling, and exhaust are optimized for compact performance, while the kick starter provides a direct, uncomplicated start method when needed. This machine is engineered to integrate premium materials and precise tolerances into a lightweight, high-revving ride.
