2016 Yamaha YFZ-450R
The 2016 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. This model has a 449cc liquid-cooled DOHC 4-stroke, 5 titanium valves. The frame is a combination of aluminum and steel for light weight. The frame member under the engine is steel, used for its combination of strength and low profile. This allows the engine to sit lower overall for excellent mass centralization for unmatched handling. The aluminum frame is bolted together, rather than welded, for maximum durability.
