Directly descended from our YZ motocrossers and WR off-road machines�even the original Yamaha YA-1 of 1955�the WR250X is here to make Yamaha�s off-road prowess street accessible.
|
|
|
|
|
|
Not exactly an enduro, a supermoto or a sportbike, the WR250X is for riders who ride mostly paved surfaces. Its sibling, the off-road inspired WR250R, is for riders who spend more time in the dirt.
|
|
|
|
|
|
|
|
250 cc liquid-cooled, DOHC engine with two titanium intake valves and two steel exhausts, forged piston and plated cylinder for outstanding durability.
|
|
|
|
|
|
Pentroof combustion chamber with downdraft-type straight intake helps make excellent power across the rev band, with maximum power at 10,000 rpm.
|
|
|
|
|
|
First use of fuel injection on a 250 Yamaha on / off-road bike. The system relies on input from a crank sensor, intake air pressure sensor and throttle position sensor feeding a compact ECU to provide optimum combustion.
|
|
|
|
|
|
An ECU-controlled EXUP� exhaust valve, along with an electronic intake control valve, broadens the powerband.
|
|
|
|
|
|
High lift cams have WPC surface treatment in which the surface is sprayed with fine powder at over 100 meters per second to increase surface hardness.
|
|
|
|
|
|
Three-axis engine layout keeps the engine compact. Wet sump tucks between frame rails to keep the engine height down.
|
|
|
|
|
|
Rare earth-type ACM alternator keeps the weight down while providing all the current needed to run the FI and lighting systems.
|
|
|
|
|
|
Direct ignition coil sits atop the spark plug�another first on a Yamaha on-off road model.
|
|
|
|
|
|
Six-speed gearbox provides a wide spread of ratios, with shower-type lubrication for reliability. Special, light-action clutch makes shifting a snap.
|
|
|
|
|
|
Tucked-in, three-chamber muffler helps keep mass centralized and the bike quiet.
|
|
|
|
|
|
Electric start only: Leaving off the kickstarter keeps it light and simple.
|
|
|
|
|
|
|
|
17-inch wheels mount radial street rubber in 110 front and 140 mm rear widths and help lower the seat approximately 1.4 inch compared to the WR250R.
|
|
|
|
|
|
One-tooth smaller rear sprocket (13/42) works with the smaller-diameter tires to bring out the WR250X�s strong accelerating character.
|
|
|
|
|
|
Stiffer springs front and rear and street-oriented damping settings reduce pitch compared to the WR250R for excellent pavement performance.
|
|
|
|
|
|
YZ/WR250-inspired semi-double-cradle frame uses a main frame of cast and forged aluminum sections, with high-strength steel downtube for excellent strength and rigidity characteristics.
|
|
|
|
|
|
Asymmetrical swingarm provides excellent strength/rigidity balance and a dynamic look. Cast aluminum crossmembers, extruded arms and a 22 mm rear axle are carefully tuned for optimum handling.
|
|
|
|
|
|
Fully adjustable 46 mm fork provides 10.6 inches of wheel travel. A forged lower triple clamp and a cast upper one help give outstanding front-end feel. An aluminum steering stem reduces weight.
|
|
|
|
|
|
Linkage-mounted rear shock provides 10.4 inches of travel with adjusters for compression damping, rebound damping and spring preload�and features a 14 mm rod and 46 mm cylinder for excellent damping and fade resistance.
|
|
|
|
|
|
Wave brake rotors front and rear, including a large, 298 mm front disc, reduce unsprung weight and provide excellent performance. Rear pedal is forged aluminum.
|
|
|
|
|
|
|
|
A slim, steel fuel tank is shaped with knee grip in mind, and the entire ergonomic layout is designed to make the rider feel like part of the bike.
|
|
|
|
|
|
Narrow, YZ-inspired seat features gripper-type cover for great seat-of-the-pants feel. Seat height is 35.2 inches.
|
|
|
|
|
|
WR enduro-style instrument panel provides excellent visibility in spite of the compact size. Basic mode provides speed, clock, tripmeter and self-diagnostic function. Measurement mode includes stopwatch, distance-compensating tripmeter, etc.
|
|
|
|
|
|
Minimalist front and rear fenders are designed for function, simplicity and lightness.
|
|
|
|
|
|
Bodywork with separate radiator heat outlet helps keep engine and rider cool.
|
|
|
|

|
Lightweight headlight and LED taillight maximize visibility and draw less current.
|
|
|
|
|
|
Separate clutch cover means easier serviceability.
|
|
|
|
|
|
One-screw air filter serviceability.
