2013 KTM 50 SX


A real KTM for the smallest of future MX champions. The 40 kg (87.7lb), lightweight 2013 KTM 50 SX sets standards in terms controllability and racing fun. It has everything including a high-quality chassis with easily applied disc brakes, top-quality components wherever you look, a powerful, reliable engine with easy-to-operate centrifugal clutch.

Features may include:
  • Handlebar
  • Made of high-quality aluminum alloy, the ergonomical Renthal handlebar ensures top stability and safety. A Renthal crash pad on the handlebar brace protects the rider from rough contact.

  • Graphics
  • Derived from the full-size SX bikes, the graphic design makes the small KTM look even cooler. Its frame has a super-rugged polymer coating in charcoal grey metallic.

  • Adjustable automatic transmission
  • Developed by KTM, the centrifugal multi-disc automatic clutch provides manageable acceleration and makes riding the motorcycle easy. It can be adjusted to the special requirements of the track and the rider without special tools.

  • Suspension
  • Both the rear shock absorber and the 35mm upside down fork from WP Suspension guarantee ultimate damping and responsiveness. Thanks to optimized tuning, the fork excels with higher reserves against bottoming out. Rebound and compression damping can be adapted to track and rider in no time at all.
