Segment: Enduro/Offroad
Production started year: 2016
The 2016 YZ450FX shares the YZ450F’s revolutionary rearward-slanted-cylinder design, with a reversed cylinder head and forward-positioned straight intake. The YZ450FX delivers a controllable, torquey power character with strong top-end power tuned specifically for cross-country racing. The obvious changes to an off-road bike are the 18” rear wheel, a skid plate (which was oddly missing from the YZ250FX), an O‐Ring Chain, an aluminum Side stand and suspension tuned for the job. A big difference from YZ motocross bike is the return of the 22mm off-set triple clamp and the use of a slightly longer shock length to raise up the rear of the bike.
