2016 KTM 450 SX-F
If this bike looks familiar, it should, as the 2015 Factory Edition was a 98% preview to 2016 450 SX-F. For 2016 the 450 SX-F features an all-new chassis and engine, reducing overall weight by 7.9 pounds. The 2016 KTM 450 SX-F is the lightest 450 MX bike in production, even with electric start. For more details, read our 2015 450 SX-F Factory Edition First Ride review.
