The 2010 Yamaha YFZ450X is the perfect machine in case wood trails racing is your game. Derived from the pro-racing R model, the YFZ450X comes with a more compact design for enhanced maneuverability. The shorter wheelbase helps riders get past uneven ground and obstacles with more ease and less fatigue.
With 4-way adjustable ProTaper handlebars and fully-adjustable piggyback KYB suspensions, the 2010 Yamaha YFZ450X is easy to set up for multiple riders. The seat is narrow in front and wider to the rear offering a lot of freedom of movement for the aggressive rider and providing a comfortable resting position, too.
Designed with wining in mind, the 2010 YFZ450X comes with the racing-specced Yamaha fuel injection for a precise throttle and titanium valves for dependable, high performance even in the most demanding of situations. A LED screen offers easy-to-read data on low fuel, coolant temperature, check engine, and neutral gear, all at a glance.
