Yamaha WR450F

With front and rear wave style brake rotors, the high performance oriented Yamaha WR450F Off-Road dirt bike has incredible stopping power which allows any woods & trail rider to slow this amazing motorcycle down fast when encountering trees, rocks and other large dirt obstacles. The WR450F has plenty of power and torque because it shared the same motor as the Yamaha YZ450F at it’s introduction in 2009 and still uses that incredible 449cc DOHC motor. The current YZ450F engines have been updated to a backward slanting front intake with rear exhaust cylinder.

While motocross racing and MX style motorcycle riding requires an essential close-ratio transmission, the Yamaha WR450F makes great use of a beefed up wide-ratio transmission with five gears and a durable strong multi plate wet clutch suited more for off road dirt style trail riding. Overall weight of the Yamaha WR450F in full operating condition filled with all vital fluids is approximately 275 pounds. This off road cycle is easy to maneuver even on the tightest trails.

The fully adjustable KYB inverted front forks and fully adjustable KYB rear shock on the WR450F helps this Yamaha dirt bike soak up rough terrain and achieve maximum traction in loose soil. When comparing the Yamaha WR450F Off-Road motorcycle to a full motocross bike like a Kawasaki KX250 side by side, you’ll see that there is hardly any difference between the two at a glance. The 450 accelerates extremely hard and has a lot of low end torque, mid range power and a lot of top end speed all through the power range for fun in any dirt bike or MX riding situation.

Yamaha WR450F motorcycles are designed for off road riding and are equipped with high quality and super strong Excel Takasago rims built with Yamaha factory hubs to create a wheel package that can take the extremely harsh demands of motorcycle woods and trail riding scenarios.

The Yamaha WR450F pushes woods and off road trail riding to the limits of motorcycle performance being nimble along with usable power delivery for fun in the dirt or on the race track.

The cool bright front headlight on the Yamaha WR450F Off-Road bike is ideal for enduro and desert night rides when motocrosser have ended their dirt riding day when the sun goes down.

The high tech fuel injected four stroke engine in the WR450F is built to perform in the dirt to Yamaha’s highest standards of performance and quality while being reliable and long lasting. Commonly known as a 4-cycle or 4-stroke motor, this motorcycle produces a lot of horsepower.

The awesome Yamaha WR450F is ready to race off road with over sized radiators, engine guards, fork guards, and racing number plates allowing the rider to compete in grueling GNCC style events.

The fuel capacity of the Yamaha WR450F is 2.1 gallons. This will provide an off road motorcycle rider the ability to go for a long ride on a single tank of gas. Premium pump gas is all you need for a full day of motocross and enduro dirt riding with no need for race fuel or premix oil to add to the gas like a 2-stroke MX bike. This 4-stroke 450 runs very efficiently being fuel injected and is very fast! 

Bore and stroke on the big 449cc WR450F liquid cooled Yamaha engine is 95.0mm x 63.4mm and the compression ratio is 12.3:1 for a high level of enduro performance and GNCC power delivery.

Along with the battery powered electric starter, the Yamaha WR450F also has a manually operated kickstarter and a compression release for trouble free and worry free starting while dirt bike riding.

The Yamaha WR450F Off-Road motorcycle takes the super high performance YZ450F motocross MX bike to another level of dirt riding options with many added features to suit a variety of riders.

A great cool feature on the durable Yamaha WR450F similar to a streetbike motorcycle is the addition of a factory mounted OEM kickstand that any person in motorcycling today can appreciate.

With aggressive motorcycle styling by Yamaha, the WR450F is a serious contender in the world of off road riding and is a popular dirt bike. It is also sometimes converted to street in Supermoto form.
