The 2010 Yamaha YFZ450X SE is a trail-racing monster, powered by a specially-tuned engine and capable to tackle pretty much any obstacles in its way. With exceptional low-to midrange rpm power and torque delivery, the 2010 YFZ450X SE offers a precise throttle thanks to the top-drawer 12-hole injection system for power maximization.
Being a racing beast, the 2010 Yamaha YFZ450X SE offers plenty of adjustability and premium options, such as a 4-way handlebar, fully-adjustable KYB suspensions, a LED screen offering data on low fuel, coolant temperature, check engine, and neutral gear.
Enhanced ergonomics provide a more comfortable stance, no matter whether riding hard in a straight line or off the seat in a fast, tight turn, while the rolled inner lip wheels provide the extra strength needed for hard landings.
