This WR250F is the aluminium-framed, five-valve, carbureted generation of Yamaha's four-stroke enduro bike, with a fully adjustable suspension and a wet-clutch five-speed gearbox. It keeps the YZ-F-derived engine in a trail-and-enduro trim with electric start. It sits just before the 2015 redesign with fuel injection and a rearward-slanted cylinder.
