Supermoto version of the WR250R: same fuel-injected 249 cc four-valve single, but on 17-inch wheels with sport radial tyres, a larger front brake disc and stiffer, firmer-damped suspension. It was meant for street and twisty-road riding with a trail-bike heritage. Specifications are unchanged from the 2008-09 version.
