2016 KTM 150 SX


The fun never ends, with all the agility of a 125 but with a power and torque increase to take the fight to the 250cc 4-strokes. For MY 2016 an all new and lighter engine producing better torque and power is fitted in a totally new chassis making the 150 even stronger and lighter. It's unbeatable and fast package which will make the new 150 SX the ultimate competitor on the track.


  • New 150 SX engine is more compact, weighs four pounds less and has more power for class dominance
  • New cylinder with revised ports and newly designed power valve unit with a sophisticated mechanism for the lateral exhaust ports gives a massive performance increase over the entire range
  • A new piston is optimized for maximum reliability with a reworked shape to fit perfectly with the new cylinder layout
  • Lighter crankshaft is optimally balanced for minimum vibrations
  • All-new die-cast engine cases raise the crankshaft and clutch shaft, centralizing mass and improving handling
  • New 6-Speed transmission provides the same gear ratios as before but is lighter and narrower
  • New "No Dirt" shift lever prevents dirt from fouling the lever joint to ensure proper shifting in any condition
  • New exhaust pipe has been tuned for the 150 SX specifically to get maximum power output from the new engine


  • New lighter Chromoly steel frame provides higher torsional rigidity with less longitudinal stiffness resulting in improved handling and energy absorption
  • New smaller, lighter subframe design made with new aluminum profiles
  • New lighter swingarm features a revised internal structure to match the new frame characteristics
  • New lighter "No Dirt" footpeg design that provides a larger surface area and features a "scraper" to reduce dirt build-up in the hinge
  • New CNC machined upper triple clamp featuring a rubber damping system for the new Neken handlebar and ODI lock-on grips
  • The advanced WP 4CS (Four Chamber System) Fork has been specifically designed for Motocross and features revised damping settings optimized for the new chassis
  • New generation WP shock has been developed in conjunction with the new frame and swingarm architecture including a new linkage/pullrod system
  • Super lightweight Galfer Wave rotors, CNC machined hubs, high-end Excel rims fitted with Dunlop GEOMAX MX32 tires are standard equipment
  • New airbox and airfilter design offers maximum protection for the engine while ensuring maximum airflow and providing quick "no tools" airfilter changes
