Features

Bodywork and Graphics

  • DECALS: The graphic design derived from that of the full-size SX bikes makes the little KTM even cooler. Its frame has a hardwearing plastic coating in anthracite metallic.
  • BODYWORK: 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.

Chassis

  • HANDLEBAR: The ergonomic Renthal handlebar made from a high-quality aluminum alloy ensures the highest levels of stability and safety. A Renthal crash pad around the center brace protects the rider from hard knocks.
  • WHEELS: Just like the big factory bikes, the 50 SX is equipped with ultra-light, black anodized aluminum rims that easily withstand even the biggest of jumps. The 50 SX is now equipped with the very latest generation tire from MAXXIS, featuring a profile that guarantees optimum grip on every surface.
  • SUSPENSION: A high quality, upside-down telescopic fork from WP Suspension, featuring 35 mm diameter outer tubes and 100 mm suspension travel, ensures outstanding ride stability. A WP shock absorber connected directly to the swingarm also supplies 147 mm of suspension travel at the rear wheel.
  • BRAKES: Both at the front and rear, state-of-the-art hydraulic disc brakes from FORMULA ensure best possible retardation. The exclusive, self-cleaning Wave brake discs stand for the ultimate in race technology and outstanding safety.

Engine and Exhaust

  • ENGINE: The modern, extremely compact, 2-stroke engine sets the benchmark in its class with its very controllable power. Thanks to the 3-shaft concept, the crankshaft is close to the bike's centre of gravity. This not only benefits the handling; it also provides a flow-optimized inflow angle at the intake membrane – a prerequisite for maximum performance.
  • CLUTCH: 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.
  • POWER REDUCTION KIT: For absolute beginners the engine power can be reduced to a moderate 5.5hp using a kit from the PowerParts catalog.
  • AUTOMATIC TRANSMISSION: The centrifugally controlled, multi-disc automatic clutch developed by KTM delivers easily controllable acceleration and makes riding the 50 SX the easiest thing in the world. Furthermore, it can still be quickly and easily adjusted to the specific requirements of both track and rider using the "KTM clicker system" - in a matter of seconds and with no special tools required.
  • COOLING: Just like the big KTM bikes, the 50 SX is also equipped with water cooling that even cools the crankcase. Generously dimensioned radiators ensure excellent heat dissipation and therefore high reliability, even under extreme loads.

Software and Electronics

  • READY TO RACE: The latest technology, reduced to the minimum.
