KX450F – 2018
- General Details
THE LIGHTEST, FASTEST 450cc MOTOCROSSER
KX design philosophy is simple: put mid-level to expert riders on the top step of the podium. This philosophy has not changed since the creation of the KX brand over
40 years ago. With 32 AMA Supercross titles to its credit, the most of any manufacturer, KX has a proven record of powering champions. Significant weight reduction to engine and chassis for 2016 makes the KX450F the lightest machine in its class. The resultant sharper handling is complemented by a slimmer chassis and an even more powerful engine, further increasing its circuit potential.*Price subject to change without notice, colours subject to availability.
