NEVER TOO YOUNG TO LEARN
The KTM 50 SX is a true KTM for young MX riders aged from around 4 to 10 years old and up to a body height of 1.30m. It is a genuine dirt bike that, like its bigger siblings, is produced with top-quality components. This makes the KTM 50 SX the first choice as a stepping stone into the world of MX or for the first racing step on the ladder. With the youngster in mind this package has an engine that delivers steady, controllable power, incorporating an automatic clutch that is ideal for novice riders. This model features revolutionary WP AER 35 front fork, fully adjustable rear suspension, ultra cool graphics and the ability to make going fast, fun. And safe.
The modern, extremely compact 2-stroke engine fitted with an automatic clutch sets the standard in its class with improved power and power band due to a new pipe. Thanks to the 3-shaft design, the crankshaft is close to the bike’s center of gravity. This does not just benefit the handling, but also allows for a flow optimized intake angle into the reed valve – a prerequisite for maximum performance.
POWER REDUCTION KIT
For absolute beginners the engine power can be reduced to a moderate 5.5hp using a kit from the PowerParts program.
The exhaust system provides a high output and a smooth power delivery over the entire rev range.
The high performance cylinder sets in conjunction with the pipe and reed intake system the performance standard within the highly competitive 50cc class.
Developed by KTM, the centrifugal multi-disc automatic clutch provides manageable acceleration and makes riding this motorcycle the easiest thing in the world. It can be adjusted to the specific requirements of the track and the rider in minutes and without any special tools.
The bodywork is derived from the full-size SX models and provides perfect ergonomics, well thought-out contact points for the rider and maximum freedom of movement. In addition, smart design solutions for the new front and rear fenders are prime examples of an intelligent design, which guarantees maximum stability through a well thought-out structure and mounting.
The modern frame produced by WP Performance Systems is made of 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.
Derived from the full-size SX bikes, the graphic design makes the new 50 SX look even cooler. Its frame has a super rugged polymer coating in cheeky black.
Made of high quality aluminum alloy, the handlebar offers top stability and safety. A slide pad on the handlebar brace protects our dearest from rough contact.
Like the big KTM bikes, the 50 SX has a liquid cooling system, which even cools the crankcase. Generously sized radiators ensure outstanding heat dissipation for high reliability, even under extremely heavy duty.
The KTM 50 SX has a modern, fully adjustable air fork: the WP AER 35, made by WP Suspension. This upside-down front fork with 35mm tube diameter and 205mm 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 just with a simple air fork pump.
On the rear wheel a WP shock absorber linked directly to the swingarm provides excellent damping performance and is fully adjustable in order set the damping perfectly to rider’s preferences and track conditions. The rear wheel travel is 185mm.
Like the big KTM factory racers, the 50 SX has super lightweight, black anodized, aluminum rims providing highest strength and safety. The OEM knobbly MAXXIS tires grip superbly on any surface.
The 50 SX is fitted with front and rear hydraulic brakes by Formula combined with lightweight wave discs that are easy to control even for the youngest riders. This ensures the best deceleration and the highest standard when it comes to safety.
