Convenient, dependable electric start ensures hassle-free, push button start.
The YZ250FX uses the “Best in Class” YZ250F reversed cylinder, rearward slanted engine with modified fuel injection settings, electric starting and a 6-speed transmission. With the optional GYT-R YZ Power tuner, you can adjust both fuel mapping and ignition mapping to best suit conditions and riding ability.
Featuring KYB “SSS” forks and a fully adjustable KYB rear shock, the FX uses the same suspension as its MX cousin with softer settings and slightly more rear wheel travel. Also included is a lightweight aluminum side stand and an 18″ rear wheel. With a maximum noise output of 94 dB, the muffler is the same as the current YZ250F.
