Yamaha YFZ 450 – The Yamaha YFZ450 ATV is billed as the lightest and most powerful ATV ever. The almighty YFZ450 has won countless magazine titles as well as the GNCC and quad-cross championships in 2004 and 2006, crowned world four-stroke champion in 2005 and 2006 and was named sport ATV of the year by ATV Illustrated in 2007. The Yamaha 2008 YFZ450 is just as potent and continues to dominate the industry.

Bringing the YFZ450 to life is a 5 titanium valve engine upon a 350 lb total dry weight setup. With the industries best power to weight ratio out of any stock ATV on the market it’s no wonder that the YFZ450 is highly competitive in every race. It’s lightweight high-tensile steel frame with fully adjustable suspension provides exceptional handling. The YFZ450 was born to race and an extreme selection of high performance YFZ450 parts are available.

The Yamaha Motor Company is offering a special edition YFZ450SE for 2008 with black and orange graphics. If you prefer red and gray graphics on your YFZ 450 you can chose those as well beginning in June 2007. Of course, the blue and white signature graphics are always an option too. Yamaha ATV enthusiasts will be styling into 2009 and beyond.
