First off, the 2015 Yamaha WR250F: This off-road machine is based off the 2015 YZ250F motocross bike but features a six-speed transmission, 18-inch rear wheel, headlight, tail light, skid plate, quiet muffler, enduro computer, and electric start. It now has fuel injection just like the YZ250F motocrosser (mapped differently to comply with green sticker regulations) and also shares the same styling. The 2015 WR250F uses the same KYB suspension as the motocross version but with different spring rates and modified valving to suit off-road riding. This is a very exciting addition to the off-road world and a welcome revamp of the older, carbureted WR250F. This is a true off-road version of the YZ250F.
