The Yamaha WR250R is a dual-sport motorcycle made by Yamaha Motor Company. It has a 250cc (15 cu in) liquid-cooled single-cylinder four-stroke DOHC engine, fed premium fuel by electronic fuel injection. It has remained largely unchanged since its introduction in 2008, with most differences being cosmetic. Despite the similar name, it shares very few common components with the lighter, non-street-legal off-road WR250F. The WR in both names indicates a wide-ratio gear box designed to offer good low-speed responsiveness in off-road situations while still being able to achieve freeway speeds.
