2012 Yamaha WR250F Review

No compromises.

A wet weight of just 260 pounds and a highly tractable 250cc titanium-valve engine make it the right tool for having fun.

A world championship winner, the proven 2012 Yamaha WR250F features enduro specific transmission and suspension settings. Not to mention the gadgets needed to “go the distance.”

If there’s one thing enduro racers can expect, it’s the unexpected.

That’s why our engineers didn’t compromise anything in design of the new WR250F. Its agility is second to none in tight wooded sections, while its YZ bred, 249cc, 5-valve engine produces hard, fast power for wide open areas. Push button start saves you energy and a digital enduro race computer with speedometer, clock and trip meter, helps set your pace.

Tight trails to open desert.

The 2012 Yamaha WR250F features a powerful and reliable engine, a YZ-bred advanced aluminum frame, push button start, and digital enduro computer with speedometer, clock and tripmeter. The 2012 WR250F is also green sticker approved for use in California.

2012 Yamaha WR250F Features and Benefits

 

ENGINE

Liquid-cooled, 249cc, 5-valve, DOHC, 4-stroke powerplant with super light titanium valves is based on the YZ250F engine design. The WR250F engine features different camshafts, ECU and exhaust system than the YZ250F for improved low to mid range power which is better suited for enduro type riding.

Super convenient electric starting means fast, sure starts. The electric starter is also backed up by a manual kick starter.

Hassle free automatic decompression system ensures fast restarts in any gear.

Convenient, handlebar-mounted hot start lever for easy restarts when the engine is hot.

Magnesium cylinder head cover helps reduce weight.

Optimized combustion chamber design provides the most efficient intake and exhaust flow for maximum engine performance

Titanium valves and load-reduced springs decrease weight by more than 40% over a conventional valve train and reduce reciprocating mass for faster-revving, smoother-hitting power delivery across the rev range.

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.”

The crankcase also utilizes cutaways to reduce “pumping losses.” The crankcase cutaways match the cutaways in the cylinder.

Dry sump oil tank is located in front of the engine between the frame tubes for protection. This design centralizes mass and reduces the centre of gravity for improved handing and a lighter feel.

The crankcase features a “tri-axis” design for the crankshaft, main and drives 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.

Special “enduro focused” camshafts (intake & exhaust) provide outstanding low to mid range power well suited for off road use.

Balancer shaft reduces vibration for great rider comfort and reduced rider fatigue.

Lightweight crankshaft provides fast throttle response.

Lightweight, short-skirt, forged piston provides great durability and its lightweight design means faster engine response.

Oil volume in engine has been optimized to reduce weight and oil “drag” related power losses.

Compact automatic cam chain tensioner reduces maintenance and mechanical engine noise.

37mm, Keihin FCR, flat-slide carburetor with TPS (throttle position sensor) provides excellent throttle response.

ECU features 3D ignition mapping and provides optimal timing at all rpms for fast engine response.

Lightweight direct ignition coil is integrated into the spark plug cap to reduce weight and complexity

Wide ratio 5-speed transmission features gear ratios designed for enduro type riding and that match the engine’s power characteristics.

Heavy-duty clutch 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.

YZ based compact dual radiators provide optimum cooling and feature a re-enforcing bar to help protect the rads in the event of a tip over.

Washable, dual-stage, foam air filter can be accessed without tools via “Dzus-type” fasteners. The air box is secured to the frame via only one bolt for fast removal.

Lightweight exhaust system features a stainless steel header pipe with titanium heat shield, aluminum muffler and titanium rear cone. This system maximizes engine power and allows hassle-free replacement of the oil filter.

Lightweight aluminum wrapped muffler offers an 82 dba noise level (stock settings). This muffler features a “serviceable”, screen-type spark arrestor which prevents sparks from exiting the exhaust.

Oversize race type “barrel adjuster” for easy, on-the-fly adjustability of clutch lever freeplay.

AIS (air induction system), located on front side of cylinder head reduces harmful emissions.

 

CHASSIS / SUSPENSION

Lightweight, compact aluminum semi-double-cradle frame features a cast steering head while the remainder of the frame uses forged, pipe stock and extruded components. 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.

Removable, aluminum rear sub frame constructed of square-section tube reduces weight and provides easy rear suspension access.

Lightweight, tapered, aluminum swingarm is produced using “hydro forming”; a special forming method that uses high pressure water to form shapes.

48mm, adjustable inverted Kayaba cartridge fork provide excellent suspension performance. Front wheel travel is 300mm (11.8″).

Front fork adjustments include: 20-way compression damping and 20-way rebound damping. Optional fork springs are available through Genuine Yamaha parts.

Large plastic 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.

Forged aluminum upper and lower triples clamp reduce weight.

Adjustable forged handlebar mounts allow the handlebars to be moved 10mm rearward if desired.

High tech, lightweight, ProTaper aluminum handlebar with reinforcing crossbar and protective foam pad.

Monocross rear suspension system features a fully adjustable, Kayaba “piggy back” style shock with separate adjusters for high- and low-speed compression damping.

Shock adjustments include: spring preload, 20 clicks of low-speed compression damping, 2 turns of high-speed compression damping and 20 clicks of rebound damping. Rear wheel travel is 310mm (12.2″).

Link-type rear suspension provides a rising rate (progressive) suspension function.

250mm fully floating front disc brake with “wave style” rotor is squeezed by a twin piston Nissin caliper fitted with lightweight, aluminum pistons providing excellent braking performance.

“Shorty style” adjustable front brake lever.

245mm rear disc utilizes a lightweight “wave style” rotor. The Nissin single piston caliper and an integrated 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.

Rugged, Excel 21″ front and 18″ rear rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance.

High tech, lightweight digital meter assembly. This compact meter features: speedometer, dual tripmeters, odometer and a clock in the basic mode. Or in the “race mode”, pace management functions such as timer, and distance compensating tripmeter.

Rugged “slim-line” bodywork allows fast, easy rider movements and a lighter overall machine feel.

Revised seat is based on YZ-F style but is wider and features new improved rider comfort during a long ride. “Gripper” or “pebble” seat cover.

Stylish slim design front headlight is compact and offers 35 watts of lighting power. The headlight beam is adjustable up and down.

Slim design compact LED taillight is tucked out of the way to prevent damage

8 liter black plastic fuel tank is designed to allow easy rider movements. The tank features a special “fluorination surface treatment” which reduces fuel permeation for improved environmental protection.

Lightweight aluminum kickstand is designed to allow lots of ground clearance.

Heavy duty one piece resin plastic engine guard. Only 3 bolts hold it in place for easy removal when washing the bike.

Extra wide 55mm stainless steel foot pegs provide excellent grip.
