2017 Yamaha YFZ450R

YOUR PODIUM AWAITS

The YFZ450R is the ultimate moto-dominating, podium-topping pure sport ATV package.

Features may include:
  • Race-Ready Engine

The YFZ450R 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 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

Bodywork is designed for great ergonomics and rider comfort, with more room to hang off in the corners, and the seat shape is padded in just the right places to improve lap times. Body panels come off easily without tools for service; 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 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.

  • Fuel Injection

The YFZ450R incorporates Yamaha Fuel Injection 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, which allows faster cornering, particularly when downshifting.

"ATVs & UTVs are recommended only for use by those aged 16 years and older. YAMAHA recommends an approved training course. See your dealer or call 1-800-887-2887. ATVs can be hazardous to operate."
