admin

Yamaha announced today that the YFZ450R and YFZ450X return for the 2011 model year with both standard models and special editions. They will be in dealerships starting in November.

Both models will come in Team Yamaha Blue and white for $8,599. The 2011 YFZ450R and YFZ450X Special Edition models, at $8,949, get new colors with a Black Metallic base, red accents and SE graphics. These Special Editions also have quick-release fasteners for no-tools installation and removal of the front and rear fenders, a black swingarm and a dealer-installed GYTR black front grab bar. More details, photos and videos are at www.Yamaha-Motor.com.

As in previous years, the YFZ450R is a motocross-ready ATV at 48.8 inches wide. It’s also set up for wide-open trails, desert terrain and sand dunes. The YFZ450X is tweaked to be a tight-trail machine at 46.1 inches wide and optimized suspension settings.

“Yamaha started the high-performance 450 sport ATV class with the original YFZ450, and we continue to dominate this class with the best options no matter where you race or ride,” Mike Martinez, Yamaha ATV and Side-by-Side Vehicle Group General Manager, stated in a press release. “Yamaha has the strongest sport ATV lineup because of our ability to constantly push performance to new levels while maintaining a customer focus and durability in our products that’s superior to anything else in the industry.”

Both models have five-valve DOHC liquid-cooled single-cylinder 449cc engines. Yamaha’s electronic fuel injection features a 42mm Mikuni throttle body, a 12-hole Denso injector system and a Mitsubishi 32-bit ECU.

The suspension on both YFZ450R and X models comes from the 44mm KYB shocks in front that have a Kashima coating for smooth operation and impact absorption. The 450R has 9.8 inches of wheel travel while the 450X has 9.4. In the back, the gravity-fed cast aluminum swingarm is matched to a fully adjustable 46mm KYB piggyback shock, affording the rear wheels 11 inches of travel on both models.

The 450R was introduced in 2008 as a racing version of the YFZ450. It had a lighter chassis with a T-shaped seat, flexible side panels, adjustable ProTaper handlebars, and custom-designed Dunlop tires measuring 21 inches in front and 20 in back.

“When you’re riding for fun with your buddies or flat-out in a race, one fast lap isn’t all you need,” said Travis Hollins, Yamaha’s ATV and Side-by-Side Vehicle Product Planning Manager. “You want to be able to ride all day and consistently pull fast times. That’s only possible if you’re comfortable on the machine — if you fit and work together as one unit. That’s what we built into the YFZ450R and YFZ450X.”
