Segment: Enduro/Offroad
Production years: 2012, 2013
In 2013, the Japanese maker launched the Yamaha WR250R, a dual-sports machine in its sixth year of production. Over its production period, the bike didn't feature any significant modifications except for minor cosmetic changes.
The Yamaha WR250R debuted in 2008 alongside its WR250X sister model that packed more street-oriented tires and sprockets. The bikes were fitted with a wide-ratio transmission with excellent low-speed responsiveness and equally great at highway speeds.
The bike was powered by a 250cc DOHC single-cylinder fuel-injected engine that featured lightweight titanium intake valves, a lightweight magnesium cylinder head, and a compact 16-bit Electronic Control Module (ECU) for fast engine response.
As for the power figures, the Yamaha WR250R boasted 30 hp with a peak at 10,000 rpm and 24 Nm (18 lb-ft) torque at 8,000 rpm from a 249cc liquid-cooled single-cylinder engine. The engine power was handled by a six-speed manual transmission and sent to the rear wheel through a final chain drive, pushing the bike to a top speed of 132 kph (82 mph).
In the suspension department, the bike packed a 46 mm adjustable Kayaba inverted fork on the front with 280 mm wheel travel and a piggyback shock absorber on the rear with 270 mm wheel travel.
As for braking performance, the 2013 Yamaha WR250R rolled on wire-spoke wheels 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.
