Incredibly fast, light and nimble... and now even more affordable!

The YFZ450 has had more than a few #1 plates on it. Its race winning pedigree is known from Coast to Coast.

An ultra-high performance sport ATV, the YFZ 450 has a powerful, industry-exclusive, five-titanium-valve engine. Combined with a 350-pound dry weight and you have one of the best power-to-weight ratios of any ATV ever produced.

ENGINE: On the track or trails power reigns supreme. The liquid-cooled, five-titanium-valve DOHC engine is a derivative of the awesome YZ450F engine that was born on a motocross track."

TRANSMISSION: A five-speed manual transmission delivers smooth power in an assortment of situations - from the starting gate to the finish line, tight trails to wide-open fire roads."

BRAKES: Stopping the machine is as easy as starting her up thanks to an all-new twin piston rear caliper. This design ensures plenty of braking power throughout the entire moto…and then some."

SUSPENSION: Independent double wishbone front suspension, offering 9.1"" worth of Nitrogen-filled, fully adjustable travel. In the rear, a single shock, cast-aluminum swingarm boasts 10.6"" of travel and a YZ-type suspension linkage."


• The eccentric shaft-type drive chain adjuster makes chain adjustments quick and easy - a must for riders on the go.

• The power of the YFZ450 is put to the ground via a set of front and rear Dunlop radials designed for ultimate cornering grip without compromising too much ride comfort. They are of course mounted on aluminum rims.

• The YFZ450 is easy on the eyes with its ultra-aggressive yet streamlined styling. Adding to the eye candy are sporty front and rear grab bars, and an LED tail light.

• One of the most popular features on the YFZ450 is its electric start, which fires both the engine and race-inspired Keihin 39mm FCR carburetor at the push of a button. Gone forever are the days of repeated, sometimes frantic, efforts to get your machine kick-started. The magic button has proven invaluable on the YFZ450, despite the machine's roots in pure sport performance.

• Also returning are the critically acclaimed one-hand operation parking brake and rider-approved 45mm footpegs.

• Dry-sump engine carries oil in an aluminum tank directly in front of the engine for excellent cooling and optimal protection from rocks or mud.

• DC ignition system delivers ultra-precise spark and 3D timing for faster, stronger engine response during hard acceleration.

• High-performance stainless steel exhaust header is mated to a USFS-approved spark arrestor.

• Smooth-shifting YZ-spec ratchet-type five-speed transmission and heavy-duty clutch deliver all that power to the rear tires with maximum efficiency.

• Large capacity airbox features no-tool access to the oiled dual foam filter for easy maintenance.

• Ignition coil is integrated into the spark plug cap; extremely light and compact.
