In 2009, the Japanese motorcycle maker released the Yamaha WR250R, a dual-sport machine part of the WR series in Yamaha's range. The bike debuted in 2008 and was in its second year of production without any modifications.
The bike and other machines with different engine displacements were part of the WR series. The WR suffix pointed towards a wide-ratio transmission with excellent low-speed response in off-road conditions but also excellent at highway speeds.
The 2009 Yamaha WR250R was fitted with standard features, such as an upswept exhaust system, a high-mounted front fender, a single seat, a small headlight in a small cowl, fork covers, and lightweight wire-spoke wheels.
The bike was built on a semi-double-cradle aluminum frame with a 46 mm adjustable inverted Kayaba cartridge-type fork on the front and a fully adjustable piggyback shock absorber on the rear, delivering excellent suspension performance and handling.
The bike's wire-spoke wheels were fitted with a 250 mm fully floating disc, a dual-piston caliper on the front, and a single-piston caliper with a 230 mm disc on the rear, delivering strong braking performance.
The 2009 Yamaha WR250R took its muscled from a 249 cc four-stroke liquid-cooled single-cylinder engine with an electronically controlled fuel injection system, delivering an output power of 30 hp at 10,000 rpm and 24 NM (18 lb-ft) torque at 8,000 rpm.
