Segment: Enduro/Offroad
Production years: 2007, 2008
The Yamaha WR250R was a dual-sport motorcycle manufactured by Yamaha from 2008, powered by a 250cc liquid-cooled single-cylinder engine fed by an electronically controlled fuel injection system.
Over its production period, the bike remained essentially unchanged, except for cosmetic modifications, along with its WR250X sister model, which was a more street-oriented machine with different tires and sprockets.
The WR suffix indicated a wide-ratio transmission designed for excellent low-speed response in off-road conditions but also excellent at highway speeds. The 2020 model marked the last production year for the WR250R.
Right from the factory, the WR250R came equipped with standard features, such as a high-mounted front fender, an upswept exhaust system, a side stand, a small cowl with a tiny headlight, a single seat, and lightweight wire-spoke wheels.
For power, the 2008 Yamaha WR250R packed a 249cc four-stroke single-cylinder liquid-cooled engine, boasting 30 hp with a maximum peak force at 10,000 rpm and 24 Nm (18 lb-ft) torque at 8,000 rpm.
For stopping power, the bike had fitted a 250 mm fully floating wave-style disc engaged by a dual-piston caliper on the front wheel. In contrast, the rear wheel was stopped by a 230 mm wave-style disc with a single-piston caliper.
The ride was softened by a 46 mm adjustable inverted Kayaba fork on the front and a fully adjustable piggyback shock absorber on the rear, offering excellent suspension performance in off-road situations.
