The Yamaha WR250R was a dual-sports machine introduced by the Japanese maker in 2008, powered by a single-cylinder DOHC fuel-injected engine. The bike was part of the WR series that comprised motorcycles with different engine displacements.
In 2012, Yamaha released the WR250R, a lightweight off-road machine in its fifth year of production that didn't bring any significant modifications whatsoever, except for minor cosmetic changes.
For appearance, the bike packed a high-mounted front fender, fork covers, a small cowl with a rectangular headlight, a single seat with a slim profile, a silver-finished aluminum frame, a half fairing, and wire-spoke wheels with off-road tires.
In the performance department, the 2012 Yamaha WR250R packed the same 249cc liquid-cooled single-cylinder fuel-injected engine as previous models, delivering an output power of 30 hp with a maximum peak force at 10,000 rpm and 24 Nm (18 lb-ft) torque at 8,000 rpm.
In the suspension department, the bike's ride was softened by a fully-adjustable piggy-back shock absorber on the rear and a 46 mm adjustable Kayaba inverted fork on the front with 280 mm wheel travel, providing excellent suspension and handling performance.
As for the stopping power, the 2012 Yamaha WR250R rolled on a set of lightweight wire-spoke wheels 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.
