One notable point of difference between the two new mounts and the YZ250F is the transmission as the WR250F and YZ250FX each get a wide ratio, six-speed gearbox. The WR250F comes with a forward positioned straight intake and a high positioned airbox, as well as a radiator fan, skid plate and electric start. The LED headlight and taillight are new and the muffler has been designed for enduro/trail riding. It comes with the same KYB fork and shock as the YZ250F, but the settings have been tweaked for it’s use as a trail bike and the 10.6 inches of travel are nearly two inches less than that of the YZ250FX and YZ250F. The WR250F has a 21-inch front, 18-inch rear wheel set-up.
The YZ250FX is an amalgam of elements from the WR250F and YZ250F. In addition to sharing the six-speed transmission, the YZ250FX also rolls on an 18-inch rear wheel, features a new side stand and electric start. The FX has the same exhaust as the YZ motocrosser, as well as the same brakes, rear shock and fork. The suspension has been tweaked a bit however to meet the needs of cross country racers.
