Yamaha YFZ450
From Wikipedia, the free encyclopedia
The Yamaha YFZ450, first introduced in 2004, was an out-of-the-box race ready All Terrain Vehicle (ATV), commonly referred to as a 'four-wheeler'. Overall, it was a very capable ATV, with good handling, braking, and overall performance.
This ATV was considered "revolutionary" and the "biggest step toward an off the showroom floor race ready ATV available by any the four major Japanese manufactures". By the end of the 2004 ATV racing season, two of the three National Championships were claimed by riders riding the Yamaha YFZ450: Keith Little, Clint and Bill Ballance.[1]

[edit] The bike
The Yamaha YFZ450 is a comfortable bike. For an ATV, it is very narrow, designed with the rider in mind. On the front, the fender is moved forward so that tall riders can fit themselves on it nicely. The acceleration and handling is all very smooth, as expected from a Yamaha ATV.[2]
Many small changes can be added to boost horsepower, such as the Yamaha GYTR Slip Exhaust, which provides 5 extra horsepower, but if you get the fmf titainium 4 you can get 11.[3]
This particular ATV is a favorite for customizers, as it comes as a powerful bike stock.
Yamaha claims that the 2007 edition of the YFZ450 is the "lightest, most powerful ATV ever, winner of just about every magazine shootout". It comes standard with a pushbutton electric starter and a flip-type parking brake. New change for the 2007 model include an aluminum handlebar, redisgned front master brake cylinder, drilled rear disc brake, and an internal oil jet. These features boost handling, braking, and improve the ride of the ATV.[4]
