Yamaha ATV – YFZ450R SE

Description

TRACK‑TAMING BEAUTY

This Special Edition features GYTR performance parts and a color and graphic scheme that looks fast just standing still.

 

  • Colors
    2 options – Available in Yamaha Black and in White
  • Race-Ready Engine
    The YFZ450R SE is the most technologically advanced sport ATV on the market today. It combines a high-tech, quick-revving, titanium-valved, 449cc fuel-injected engine with a lightweight, professional-caliber cast aluminum/steel chassis. The power and chassis combination makes for a championship-winning machine time and time again.
  • Advanced Frame
    The YFZ450R SE is motocross-ready. The weldless frame is designed from lightweight aluminum with a tension-steel bottom frame that lets the engine sit lower for excellent mass centralization. Suspension components and settings reduce weight while providing light, sharp handling and rider comfort.
  • Aggressive Bodywork
    With more room to hang off in the corners, the bodywork is designed for great ergonomics and rider comfort. The seat shape is padded in just the right places to improve lap times while the body panels come off easily without tools for service, so there’s no need to remove the battery or other components to take the fenders off.
  • Advanced Cylinder Head
    The 449cc engine uses titanium five-valve cylinder head technology 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.
  • Fuel Injection
    The YFZ450R SE incorporates Yamaha Fuel Injection (YFI) for precise fuel delivery. With a big 42mm Mikuni® throttle body and 12-hole injector, this system provides exceptional atomization of the fuel for maximum power. The system also includes ISC (Idle Speed Control) for easy, reliable start-up and warming.
  • Assist and Slipper Clutch
    An assist-and-slipper clutch reduces clutch lever effort for less fatigue while at the same time increasing clutch plate pressure for positive engagement. This clutch system also reduces engine braking effect for faster cornering, particularly when downshifting.
  • Aggressive SE Style
    Aggressive styling gives the YFZ450R SE a racy customized look with extras like the GYTR® front grab bar to match its unique graphics package.
