Welcome To the New ATV World Order
Very simply, the YFZ450 is the most competition-ready production ATV that’s ever been built, and the winner of just about every major magazine shootout.**

“The YFZ is the best sport quad that has ever been made.” ATV Rider, 2004

“… the Yamaha YFZ450is at the top of the high-performance class.” Dirt Wheels, 2004

Not only is the hybrid 439cc DOHC titanium-valved five-speed engine far superior to anything that's come before, at 350 pounds, the YFZ450 is endowed with the highest power-to-weight ratio of any four-stroke ATV ever built.

Yes, it even has electric start, and when you open the 39mm Keihin carburetor all the way, you'll also appreciate the lowest center of gravity in the class and the latest industry-leading suspension technology.

The Special Edition model adds a sportier, more menacing edge with a black frame, yellow bodywork with black accents.

But we’re just getting warmed up here, so why don’t you visit the Features & Benefits page to get a closer look at the YFZ450's list of incredible features.

It's simple. You'll either be riding a YFZ450 this season or trying to catch up to one.

Special Edition Available from October 2004
