Yamaha WR 250X

An outstanding no-compromise Supermotard, the WR250X is based on Yamaha's champion WR-F and YZ-F off-road race bikes, and is built to deliver utter exhilaration - whether on city streets or twisty back roads.

Revving hard all the way to 10,000 rpm, it's powered by a liquid-cooled, 4-valve, 4-stroke DOHC single-cylinder engine. With electronic fuel injection and a 6-speed gearbox, the WR250X runs hard and fast, while the 298 mm front disc and 230 mm rear disc scrub off speed at your command.

Compact, lightweight and brilliantly agile, it features 17 inch wheels with sticky sports tyres, aluminium frame, upside-down front forks and a link-type Monocross rear suspension system

Just like its WR250R counterpart, the WR250X features an ergonomic layout that has been designed to ensure maximum comfort while riding the bike out on pavement. It comes with a narrow, YZ-inspired seat features and a gripper-type cover for a comfortable feel on the seats. Speaking of the seats, it carries a height of 35.2." The WR enduro-style instrument panel also provides excellent visibility in spite of its compact size. Two modes - Basic and Measurement - offer all the pertinent information a rider needs for his travails. The Basic mode provides the speed, clock, tripmeter, and self-diagnostic function while Measurement mode features a stopwatch and a distance-compensating tripmeter, among other things. The front and rear fenders have also been designed with greater importance put on the bike’s overall function, simplicity, and lightness. Meanwhile, the bodywork and the separate radiator heat outlet helps keep the engine cool, providing comfort for both the bike and driver.
Performance

The Yamaha WR250X is powered by a 250cc liquid-cooled, DOHC engine with two titanium intake valves and two steel exhausts, forged piston and plated cylinder for outstanding durability. The engine is then mated to a six-speed gearbox that provides a wide spread of ratios, with shower-type lubrication for reliability. A Pentroof combustion chamber with downdraft-type straight intake helps make excellent power across the rev and, with maximum power at 10,000 rpm. An ECU-controlled EXUP exhaust valve, together with an electronic intake control valve, broadens the engine’s overall powerband.

The bike also carries high-lift cams carry a WPC surface treatment with a sprayed fine powder surface to increase surface hardness. In order to keep the engine height down, Yamaha added sump tucks between the frame rails while a rare earth-type ACM alternator keeps the weight down, providing all the current needed to run the FI and lighting systems. Just atop the spark plug, Yamaha installed a direct ignition coil while a tucked-in, three-chamber muffler helps keep mass centralized and the bike relatively quiet, an achievement in its own right.
Brakes and Suspension

The Yamaha WR250X comes with a WR250-inspired semi-double-cradle frame that uses a main frame of cast and forged aluminum sections, with a high-strength steel downtube for excellent strength and rigidity characteristics. An asymmetrical swingarm provides excellent strength and rigidity for a more balanced and dynamic look while cast aluminum crossmembers extruded arms and a 22mm rear axle are carefully tuned for optimum handling. A fully-adjustable 46mm fork provides 10.6 inches of wheel travel. A forged lower triple clamp and a cast upper one help provide outstanding front-end feel.

The bike also features stiffer and sturdier front and rear springs with street-oriented damping settings that reduces pitch compared to the WR250R for excellent
pavement performance. As far as brakes go, the Yamaha WR250X comes with front and rear wave brake rotors, including a large, 298mm front disc, significantly reducing the bike’s unsprung weight thereby providing excellent performance.
