2016 KTM 450 SX-F


If asked for maximum power there is no other way but the KTM 450 SX-F. This model has proven itself in championships around the world over the years. Thanks to its compact SOHC engine that delivers explosive but controllable power, it is the weapon of choice for the US KTM Factory Team's successful 2013 & 2014 AMA Motocross Outdoor championships and 2015 AMA Supercross Championship. For 2016 the 450 SX-F presents itself with an all new chassis and engine, reducing overall weight 7.9 pounds making the new model even easier to ride. All the while, setting a new benchmark of 62hp in terms of peak power. The 2016 KTM 450 SX-F is the lightest, fastest 450 MX bike on the track, consider the game changed.


  • The new 450 SX-F engine design is more compact, lighter and provides higher performance throughout the entire range of power
