2011 Yamaha WR250X model Features
• Fuel Consumption * 30kpl/85mpg(Imp)
• 250cc, fuel injected engine
• Lightweight aluminium frame & swingarm

• Potent, liquid-cooled, 250cc, DOHC, 4-valve, 4-stroke powerplant with super light titanium intake valves and electronic fuel injection.
• Super convenient electric starting means fast, sure starts.
• Hassle free automatic decompression system ensures fast starting and reduces battery size and weight.
• Lightweight magnesium cylinder head cover helps reduce weight.
• Double overhead cam, 4-valve combustion chamber features a compact "pent-roof" design for maximum breathing efficiency.
• Downdraft -type straight design intake port provides the most efficient intake flow for maximum engine performance.
• Intake side, lightweight titanium valves and load-reduced springs decrease weight by more than 40% (Vs steel valves). Titanium valves reduce reciprocating mass for faster-revving, plus reduced frictional losses for smoother-hitting power delivery across the rev range. Intake valves are 30mm in diameter, while the steel exhaust valves are 24.5mm in diameter.
• Steep valve angles, 11.5 degrees on the intake side and 12.5 degrees on the exhaust produce a more compact combustion chamber.
• Dual electrode NGK CR9EK spark plug is located in the centre of the combustion chamber for fast, controlled combustion and great throttle response.
• Ceramic composite cylinder provides excellent heat dissipation for consistent power delivery, reduced oil consumption, reduced friction for increased power and reduced weight.
• Special cylinder design features cutaways that allow the air "trapped" under the piston to enter a side chamber (or cutaway) to reduce horsepower-robbing "pumping losses."
• Special design crankcases also utilize cutaways to reduce "pumping losses." The crankcase cutaways match the cutaways in the cylinder to reduce 'pumping losses.
• The crankcases feature a "tri-axis" design for the crankshaft, main and drive axles. This tri-axis design keeps the crankcases more compact while also centralizing mass for better handling. All of the shafts are positioned low in the cases to maintain a low centre of gravity for great handling and maneuverability.
• Lightweight, high strength, short-skirt, forged aluminum piston provides great durability and its lightweight design means fast engine response and less mechanical vibration.
• Lightweight roller bearing style crankshaft with optimized mass delivers excellent fast and strong acceleration.
• Single balancer shaft reduces engine vibration for improved rider comfort and reduced rider fatigue. This bike can cruise at highway speeds comfortably.
• Special design high performance camshafts (intake & exhaust) provide outstanding class leading power. The cams feature a WPC (Wonder Process Craft) treatment that increases surface hardness for great durability and reduced sliding resistance.
• Wet sump lubrication system is used. This system reduces weight and the number of moving parts versus a dry sump system. Piston oil cooler nozzle is used to maintain consistent piston temperatures for durability.
• Oil volume in engine has been optimized to reduce weight and oil "drag" related power losses.
• Easy access paper-type oil filter is used.
• Compact hydraulic automatic cam chain tensioner reduces maintenance and mechanical engine noise.
• 38mm Mikuni electronic throttle body type fuel injection system is used. This system is a return-less FI system with TPS (throttle position sensor). This system provides excellent throttle response, great fuel economy, reduced emissions and a choke-free design. Throttle response and acceleration are excellent.
• Long nozzle type 12 hole injector is used and provides a dual spray pattern for best in class performance.
• Easy to service 4.1 liter airbox with an intake control valve provides state of the art intake and emission control. The foam air filter is a washable design
• Compact 16 bit ECU features 3D ignition mapping to accommodate the engine power characteristics. The ECU provides optimal timing at all rpms for fast engine response.
• Lightweight direct ignition coil is integrated into the plug cap to reduce weight and complexity
• Wide ratio 6-speed transmission features gear ratios designed for both on and off road riding. This transmission adopts a "shower type" lubrication system for great reliability.
• Heavy-duty clutch matches engine output and offers a light, progressive clutch feel with less lever effort for smoother shifting.
• Quick-access, lightweight aluminum outer clutch cover allows fast, easy access to the clutch.
• Single, 9.5KW rad is used. The "exhausted air" (after it has passed through the rad) is directed away from the rider for excellent rider comfort. An electric cooling fan maintains consistent engine temperatures even in stop and go traffic. The single rad is located on the left side of the fuel tank.
• Lightweight, compact "rare-earth-type" ACM (Alternative Current Magnet … 14V & 350W output) is used.
• Lightweight exhaust system features a stainless steel header pipe and a compact 3-stage expansion type upswept muffler with a honeycomb catalytic converter to reduce exhaust emissions. This system maximizes engine power and allows hassle-free replacement of the oil filter. It features a cleanable screen-type spark arrestor. Heat shields protect rider and passenger.
• The exhaust system also features Yamaha's EXUP System (Exhaust Ultimate Power Valve). The single butterfly valve prevents the "blow back" phenomenon caused by "valve overlap". The EXUP system eliminates "flat spots" in the power band and reduces emissions too.
• Solenoid activated AIS (Air Induction System) reduces harmful exhaust emissions like carbon dioxide and hydro carbons.

• Lightweight, compact aluminum semi-double-cradle frame features a variety of components. The main frame is cast aluminum, while forged aluminum is used under the main frame below the steering head area and separate detachable down tubes are thin walled high tensile steel. Yamaha has maintained the semi double cradle design to allow for "controlled flex" to optimize suspension action. This frame design provides a low centre of gravity for a light feel and razor sharp handling, plus less rider fatigue, and excellent stability.
• Detachable high tensile steel rear sub frame is constructed of round steel pipe. The detachable design provides easy rear suspension access and reduces costs in the event of loop out. .
• Lightweight, tapered, aluminum swingarm features a mix of extruded, cast and forged parts. The main arms are extruded while the cross member at the front is cast and the rear portion at the chain adjusters are forged. This unique rear arm provides the best rigidity-strength balance plus a dynamic look too. The suspension links are located below the arm to maintain a low center of gravity for razor sharp handling.
• 46mm, adjustable inverted, Kayaba cartridge fork provide excellent suspension performance. Front wheel travel is 270mm (10.6"). Front fork adjustments include: 19-way compression damping and 17-way rebound damping. NOTE: The fork settings are different and unique for the X / Supermoto version
• Cast aluminum upper triple clamp and forged aluminum lower triple clamp reduce weight and provide excellent strength. The steering stem is light weight aluminum. The fork features a 25mm offset and a 28mm axle offset for great stability and neutral steering characteristics.
• Competition YZ inspired "cantilever style" fork protectors wrap around the fork tubes for increased protection against dirt, mud and stone chips. These fork protectors are self-supporting to reduce friction for smoother fork operation.
• Monocross rear suspension system features a fully adjustable, piggy-back style shock. The damping rod is 14mm in diameter while the actual shock body is 46mm in diameter. Rear shock adjustments include: spring preload, 12 way compression damping and 23 way rebound damping. Rear wheel travel is 265mm (10.4"). NOTE: The rear shock settings are different and unique for the X / Supermoto version.
• Link-type rear suspension provides a rising rate (progressive) suspension function. The linkage design is very similar to those used on the YZ/WR competition line-up.
• Large, stainless 298mm fully floating wave-style front disc is squeezed by a twin piston Nissin caliper fitted with lightweight 27mm aluminum pistons. Nissin front master cylinder features a 12.7mm piston. Braking performance is excellent. Sintered metal pads are used
• Stainless 230mm rear disc utilizes a lightweight "wave style" rotor. The Nissin single piston caliper and an integrated Nissin rear master cylinder (fluid reservoir is integrated into the top of the master cylinder to reduce weight) delivers strong, progressive stopping power with excellent control and feel. Sintered metal pads are used
• Rugged yet light aluminum DID 17" (17 x MT3.00) front and 17" (17 x MT4.00) rear rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance. Both rims utilize straight pull spokes. Radial tires are used front and rear.
• Competition WR series inspired lightweight, digital meter assembly. This compact meter features: speedometer, odometer, dual tripmeters, and a clock plus FI system diagnostics in the basic mode. A stopwatch and adjustable tripmeter can be found in the "measurement mode".
