- 2006 Yamaha WR250F

The WR250F is back for 2006 with the same dominating attitude it's always had, plus a whole whack of new features guaranteed to extend its stellar reputation -- and give you the ride of your life.

We've started with some modifications to the head and combustion chamber for better breathing, dropped on a larger 48mm fork, and capped things off with a lower, slimmer seat. Turn it over with effortless electric start and ride with more power, better maneuverability, and a lower dry weight than ever before. The result is a lighter, more nimble WR that's ready to trounce the toughest trail.


Engine:

Liquid-cooled, 249cc, 5-valve, DOHC, 4-stroke powerplant with trick titanium valves produces smooth-hitting, low- and mid-range torque with a broad powerband tuned specially for enduro/off-road riding.

Ultra-convenient electric starting means fast sure starts. The electric starter is also backed up by a manual kickstarter.

Automatic decompression system ensures fast restarts in any gear.

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

Compact cylinder head design and magnesium cylinder head cover help reduce weight and engine size.

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."

Lightweight crankcase also utilizes cutaways to reduce "pumping losses." The crankcase cutaways match the cutaways in the cylinder.

Forged piston features a convexed shape on the piston crown to match the special intake port design. The lightweight forged piston reduces reciprocal mass and friction for faster revving and greater durability.

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

Dry sump lubrication system uses the frame as an oil tank, helping to create a more compact engine and chassis for superb handling performance. Oil volume has been optimized to reduce friction and weight while still supplying the precise amount of oil for proper engine lubrication.

Revised 37mm Keihin FCR-MX flat-slide carburetor with throttle position sensor (TPS) ensures ultra-precise fuel/air mixing and lightning-quick throttle response. The carb settings have been changed for 2006. The specifications of the air jet, leak jet and jet needle have been revised.

No tools required air box utilizes a washable, dual-stage air filter.

New Air Induction System (AIS) reduces harmful exhaust emissions for a cleaner , more environmentally friendly engine. The AIS system reduces hydrocarbons (HC) and carbon monoxide (CO) emissions by injecting fresh air into the exhaust port to completely burn any unburned gases in the exhaust.

Slick-shifting, wide-ratio, 5-speed transmission with heavy-duty, multi-plate clutch is geared specially for broad, off-road/ enduro power delivery. Involute splines on the transmission main and drive axles mean smooth, positive shifting.

Heavy-duty clutch matches engine output and offers a light, progressive clutch feel with less lever effort for smoother shifting.

Quick-access, lightweight outer clutch cover allows fast, easy access to the clutch.

CDI ignition system delivers a more precise spark and monitors engine speed to ensure optimal timing for fast engine.

Lightweight direct ignition coil is used to reduce weight and complexity. The ignition coil is built into the spark plug cap, reducing weight and complexity.

Large-capacity, dual radiators use special louvers to direct airflow through the rads to ensure maximum cooling efficiency.

Revised header pipe features a specially shaped header angle maximizes engine power and allows hassle-free replacement of the oil filter. The header pipe is made of stainless steel and features a heat shield.

Lightweight aluminum wrapped muffler optimizes both power delivery and appearance. This muffler features a "serviceable" screen-type spark arrestor which prevents sparks from exiting the exhaust. Its repackable design means you can maintain optimal engine performance and reduce noise levels as the packing deteriorates.

Trick, works-style clutch lever features an oversize "barrel adjuster" for on-the-fly adjustability of clutch lever play. There is a new, larger boot covering the adjuster that provides more grip for easier operation.


Chassis/Suspension:


Super-strong, semi-double-cradle frame reduces weight and provides great lateral rigidity for minimal flex and razor-sharp handling.

Removable, aluminum, rear sub frame constructed of square-section pipe reduces weight and provides easy rear suspension access. For 2005, new conventional hex head bolts have replaced the Allen-style bolts that secure the sub frame to the main frame for easier, faster servicing.

New, lightweight, tapered, aluminum swingarm is produced using "hydro forming", a special forming method that uses high pressure water to form shapes. The new swingarm provides improved overall chassis balance thanks to the addition of re-enforcing ribs in the cast aluminum around the pivot area. The result is a 2% increase in torsional rigidity for improved handling.

Revised 48mm, adjustable, inverted Kayaba cartridge fork provide excellent suspension performance. The outer (male) tube is changed to optimize rigidity and is Kashima coated to reduce friction.(changed from Alumite) . The center rod size has been reduced form 8mm to 6mm while the cylinder diameter has been increased from 25 to 28mm. This new fork no only offers excellent suspension function but also reduces weight too.

A new oil lock system in the new fork is now utilized. This new oil lock system enhances suspension performance and improves rider comfort.

The 48mm fork utilizes a Transfer Control Valve (TCV) which enhances the damping force from mid stroke to full stroke and improves bottoming characteristics. The benefit of TCV is more precise control throughout the full stroke range.

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.

New larger plastic fork protectors wrap further around the fork tubes for increased protection. They are self-supporting design to reduce friction for smoother fork operation. The routing of the wiring for the new electric speed sensor (no longer a traditional cable) now passes on the inside of the fork leg protector for added protection.

Revised upper and lower triple clamp feature a new painted mat titanium finish for an improved appearance.

New adjustable handlebar mounts on the top triple clamp allow the handlebars to be moved 10mm rearward if desired.

Lightweight, Renthal aluminum handlebar with reinforcing crossbar and foam pad

Monocross rear suspension system features a revised, fully adjustable, Kayaba shock. This new shock now features a dark gold coloured shock body and new revised settings for improved rider comfort and handling. 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 305mm (12").

250mm, fully floating front disc brake with twin piston caliper fitted with lightweight aluminum pistons provides excellent braking performance. Revised shorty style adjustable front brake lever offers improved hand comfort and grip.

Revised 245mm rear disc brake utilizes a new single piston caliper. The caliper is mounted lower on the swingarm to add additional clearance for the exhaust pipe. The rear master cylinder is integrated with the fluid reservoir to reduce weight. This revised set-up delivers strong, progressive stopping power with excellent control and feel.

All new multifunction digital meter assembly. This compact meter features 2 modes. The first is the "basic" mode and features: speedometer, odometer, resettable dual tripmeters, and a clock. The second is the race mode and it features speed, an automatic start timer, and the ability to edit the tripmeters and an odometer.

New, lightweight, rugged Excel 21" front and 18" rear rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance.

New design front fender and seat. The seat base and foam has been revised for more cushioning effect and improved rider comfort.

Sun Star specially designed rear sprocket increases the contact area between the sprocket and chain rollers, thereby reducing the load on the chain and increasing service life of both chain and sprocket.

The regulator has been re-located to the steering head area.



Features:

Premium Dunlop knobbies offer great traction and excellent wear.

"Slim line" bodywork is very similar to the YZ bodywork. The fuel tank capacity is 8 litres. The "slim line" body allows fast, easy rider movements and a lighter overall machine feel.

Enduro-style lighting front and rear increase versatility by maximizing nighttime and low-light visibility.

On-off-reserve fuel petcock provides peace of mind.

Wide, serrated, folding, cast alloy footpegs provide excellent grip.

Serrated rear brake lever and folding shift lever tip offer superb grip and excellent durability.

Specially designed, detachable, lightweight, aluminum kickstand folds well out of the way and allows lots of ground clearance.

Inner clutch cable is stainless steel for longer life.

Rugged engine and water pump protector plates

All new lighter plastic, lower rear disc protector

Newly designed rear caliper protector

Low-maintenance, sealed, gel-type battery

Waterproof starter button and engine kill switch are handlebar-mounted

Handy lifting holes in the side covers
