2024 Yamaha YFZ450R SE

Track-taming Beauty

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

Top Features

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.

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 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.

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.

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.

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.

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.

Additional Features

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.

Compact LED Indicators: The discreet panel on the fender in front of the rider gives vital indicators about low fuel, coolant temperature, check engine and neutral gear via an LED display.

Light Throttle Action: The throttle lever requires low effort for less fatigue during long motos.

Chassis Suspension Features

Adjustable Handlebar: The large-diameter tapered handlebar reduces vibration and is mounted on four-way clamps for exceptional adjustability. The two sets of holes in the handlebar crown and the eccentric clamps allow the rider to choose the standard setting: 10mm forward, 20mm forward or 10mm backward.

Advanced Frame: The lightweight frame is a combination of aluminum and steel. The frame member under the engine is steel and is used for its strength and low profile so that the engine can sit lower overall for excellent mass centralization and unmatched handling. The aluminum frame is bolted together, rather than welded, for maximum durability.

Durable, Rigid Wheels: The wheels have been designed with the inner lip rolled in to increase rigidity, allowing for a reduction in weight while maintaining strength.

High-Performance Shocks: The front KYB® shocks are longer for increased stroke, superb bump absorption and excellent anti-bottoming characteristics. The Kashima™ coating offers smooth operation while the 9.8 inches of wheel travel means the racer is ready for the most challenging tracks.

Long A-Arm Suspension: The front frame is as narrow as possible at the A-arm mounting points.
