The YFZ-450R is the most technologically advanced sport ATV on the market today. It is simply the top of the line “racing” level Sport ATV. It combines a high-tech, quick-revving, titanium five-valve, 449cc fuel-injected engine with a lightweight, professional-caliber cast aluminum/steel chassis. The power/chassis combination will make for a championship-winning machine time and time again.
The 449cc engine uses titanium five-valve cylinder head technology designed to deliver abundant power in the mid-range to top end, with more “hit” feeling right off idle. The higher compression ratio further improves overall engine performance.
