In 2011, Yamaha launched the WR250R, a dual-sports motorcycle manufactured by Yamaha from 2008, part of the WR series and powered by a 250cc single-cylinder DOHC engine with an electronically controlled fuel injection system.
The bike was built alongside the WR250X, packed with more street-oriented tires and sprockets. The WR suffix indicated that the bike features a wide-ratio transmission for low-speed responsiveness in off-road conditions but also handling highway speeds.
In the appearance department, the 2011 Yamaha WR250R featured a high-mounted front fender, a small cowl with an LED headlight, a single seat, a slim profile, an upswept exhaust system, and wire-spoke wheels with off-road tires.
The bike's wire-spoke wheels were fitted with a dual-piston caliper, a 250 mm disc on the front, and a single-piston caliper with a 230 mm disc on the rear, offering excellent stopping power.
As for suspension, the bike's ride was softened by a 46 mm adjustable Kayaba inverted fork on the front with 270 mm wheel travel. The rear end was operated by a fully-adjustable piggyback shock absorber with 270 mm wheel travel, delivering excellent handling.
As for the power figures, the 2011 Yamaha WR250R boasted 30 hp on tap at 10,000 rpm and 24 Nm (18 lb-ft) torque at 8,000 rpm from a 249cc four-stroke liquid-cooled single-cylinder engine.
The engine power was handled by a six-speed manual transmission and delivered to the rear wheel through a final chain drive.
