The KTM 65 SX is a fully-fledged race machine for young pilots aged between 8 and 12 years. This little flyer features the latest WP XACT front forks with revolutionary AER technology, ultra-cool graphics and a power delivery that sets the benchmark in its class. Like its larger counterparts, the KTM 65 SX has READY TO RACE ride dynamics, quality equipment and superior craftsmanship, providing winning performance to young competitors.
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.
The high performance cylinder features a pressure-controlled exhaust valve (PCEV) and provides unrivaled performance within the highly competitive 65 cc class.
An outstanding feature of the KTM 65 SX is the hydraulic clutch made by Formula. It provides easy clutch action and well-defined modulation.
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.
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.
The KTM 65 SX is fitted with a lightweight cast aluminum swingarm. Conceived using the latest in calculation and simulation software, the focus of the design was for minimum weight, optimum stiffness and precisely defined flexibility. In addition, it features a robust 2-compound chain guide, similar to the full-size models.
Like the full-size KTM Factory racers, the 65 SX has super lightweight, black anodized, aluminum rims providing the highest strength. The OEM MAXXIS knobbly tires grip superbly on any surface.
The KTM 65 SX is the first model in its class to be fitted with a modern, fully adjustable air fork: the WP XACT AER fork. The upside-down front fork with a 35mm tube diameter and 215mm 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.
The high quality WP XACT shock absorber is linked directly to the swingarm, providing excellent damping performance. It is fully adjustable, meaning you can set the damping perfectly to suit the rider’s preference and track conditions. The shock absorber allows for 270 mm of rear wheel travel.
The front and rear brakes have massive 4 piston calipers that grip lightweight wave brake discs – 198 mm front and 160 mm rear. The hydraulic brake system is easy to control and ensures the best deceleration and the highest standard when it comes to performance.
A new high-quality tapered handlebar made from aluminum alloy has the perfect bend to suit the ergonomics and the highest strength. A new slide pad on the handlebar protects the rider in the event of contact. Additionally, the bike comes standard with ODI lock-on grips, which include a vulcanized grip on the right side and a lock-on grip on the left that does not require glue or wire for mounting.
BODYWORK & GRAPHICS
The 2021 KTM SX models feature the latest in-mold graphics, matching the factory-look orange frames and bodywork perfectly. They have a fast and aggressive style that screams READY TO RACE, leaving no doubt as to the bikes’ high-performance intentions.
