Yamaha is rolling out a pair of new all-purpose bikes that have been designed to make commuting, be it on pavement or off-road, as seamless and efficient as possible.
One of this is the supermoto-influenced WR250X, which is about as legitimate as any dual-sport bike you’ll find on the market today. The WR250X offers an unmatched level of riding performance and excitement that very few bikes in the market can provide.
The bike was built using inspiration from two legendary Yamaha models, the YZ motocrossers and the WR off-road machines. But unlike the WR250R, which was designed and built for off-road purposes, the WR250X was built with a little more cosmopolitan use to it.
Whatever adventures you may chance upon with this bike, you’ll always remember that the WR250X is a bike that can take you wherever you need to go. It not only delivers a fun and enjoyable ride, but also gives you everything you need in a two-wheeled, pavement-riding machine.

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.
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 band, 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.

Motorcycle.com says " This Good Dual Purpose " with Engine Potent, liquid-cooled, 250cc, DOHC, 4-valve, 4-stroke powerplant with super light titanium intake valves and electronic fuel injection. Rarely has a quarter-liter streetbike been this much fun. The Ninja 250 has its sportbike appeal, but it’s lacking the bad-ass gene that is so apparent in the WR250X supermoto. Hayabusa pilots might not think much of its 28 horses at the back wheel, but it’ll lap the Busa within four circuits of your local go-kart track!
