2025 Yamaha YFZ450R

CHAMPIONSHIP COLLECTOR. Boasting podium-topping DNA and serious racing pedigree, this is the unmatched, race-ready Sport ATV for those who want to win.

Features may include:

  • CAPABILITY

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.

  • COMFORT

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.

  • CONFIDENCE

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 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.
