New 2022 KTM 65 SX Dirt Bike Motorcycle

The KTM 65 SX is sharing the same development strategy as the bigger 2-Strokes. It has everything the bigger bikes do, from a proper clutch and gearbox to the latest WP XACT front forks with revolutionary AER technology, modern, aggressive graphics, and power delivery that sets the benchmark in its class. Like its larger counterparts, the KTM 65 SX has real-world READY TO RACE written all over it.

Engine & Exhaust

• Engine: The KTM 65 SX features cutting-edge 2-stroke technology and an easy-to-shift 6-speed transmission with a hydraulic clutch. Benefitting from a reworked ignition curve, the cylinder, with its pressure-controlled exhaust valve, continues to provide class-leading power and plenty of torque.
• Cylinder: The high performance cylinder features a pressure-controlled exhaust valve (PCEV) and provides unrivaled performance within the highly competitive 65 cc class.
• Clutch: An outstanding feature of the KTM 65 SX is the hydraulic clutch made by Formula. It provides easy clutch action and well-defined modulation.
• Cooling: An intelligent cooling circuit with integrated crankcase cooling and two radiators improves the heat dissipation and ensures a constant temperature balance for consistent, high performance.

Chassis

• Frame: The modern frame is made from lightweight, high strength chromoly steel profiles and combines maximum longitudinal stiffness with optimum torsional rigidity. It guarantees easy handling and precise cornering, but also outstanding stability.
• Swingarm: Taking charge at the rear is a lightweight cast aluminum swingarm. Conceived using the latest in calculation and simulation software, the focus of the design was to minimize weight, optimize stiffness and clearly define flexibility. Additionally, it also features a robust 2-compound chain guide, similar to the full-size models.
• Wheels: Like the full-size KTM Factory racers, the KTM 65 SX is fitted with lightweight, black anodized, aluminum rims which provide the highest strength and durability for any eventuality. These are fitted with OEM MAXXIS knobbly tires, to provide unmatched traction on any surface.
• Front Suspension: The KTM 65 SX is the first model in its class to be fitted with a modern, fully adjustable air fork: the WP XACT fork with AER technology. The upside-down front fork with a 35 mm tube diameter and 215 mm of travel ensures outstanding comfort, damping characteristics and directional stability. Another main benefit for junior riders is that the air spring fitted in the left fork leg can be adjusted perfectly to the rider’s weight using a simple air pump.
