2008 YAMAHA WR WR450FXL

2008 Yamaha WR450F

Power with control.

The 2008 Yamaha WR450F was all new from the ground up last year. A lightweight aluminum frame and swingarm, all new slim line bodywork and the potential for full YZ performance were a few of the key ingredients the engineers added to the mix in 2007. For 2008, the biggest WR gets a special "fluorination" treatment on the fuel tank to reduce fuel vapour emissions, plus some minor changes to the front brake for reduced weight.

Everything else trails far behind. It’s got the muscle to shoot you up to steepest hills with the greatest of ease and can go over, around or through just about anything the trail cares to throw your way. All you need to bring is gas and as much off-road skill as you can muster.

Based on the latest version of our YZ-F four stroke motocrosser, the WR450F features a lightweight aluminum frame and stylish "slim line" bodywork specially designed to provide excellent rider maneuverability.

The WR450F utilizes YZ based adjustable suspension front and back and YZ brakes featuring the latest wave style rotors and compact calipers. It’s got the power to tame any trail. The 2008 WR450F is the most powerful, sharpest most focused big bore WR we have ever built.

FEATURES:

Liquid-cooled, 449cc, 5-valve, DOHC, 4-stroke powerplant with super light titanium valves is based on the current YZ450F engine design. The WR450F engine features cam shafts, ECU, and exhaust which vary slightly from the YZ450F for improved low to mid range power better suited to enduro usage.

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 cylinder inclination angle (4.5 degrees) to centralize mass and bring the center of gravity closer to the rider for great weight distribution and light handling.

Optimized intake port shape increases the velocity of the incoming charge for more complete cylinder filling and more power.
