2023 Yamaha YFZ450R SE

The 2023 Yamaha YFZ450R SE is back and ready for all of your high performance off-road needs. Check out the top features, specifications and photos of the Special Edition YFZ450R.

2023 Yamaha YFZ450R SE Top Features

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 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.

2023 Yamaha YFZ450R SE Features & Benefits

ENGINE

Powerful Engine: The fuel-injected 449cc engine has superb power characteristics. Power delivery is smooth and strong off the line with lots of mid-range and top-end power.

Advanced Cylinder Head: The 449cc engine uses a five-valve cylinder head and titanium valve technology to deliver abundant power in the mid-range to top-end with more “hit” feeling right off idle. The high 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.

Compact Counterbalanced Engine: The crankcase holds a crankshaft that’s ready to handle the increased demands of the racer, as well as a counterbalancer to reduce vibration. The crankcase also houses the oil tank which helps to centralize mass for unmatched handling while making maintenance easier.

Tuned Camshafts: Camshafts have been revised to maximize the engine’s impressive power output from off the line all the way up to the top-end.

CHASSIS/SUSPENSION

Race-Ready Ergonomics: The body configuration allows more room for the racer to move around during the moto. To reduce fatigue, the seat is narrow in the front yet wide and padded in the rear.

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.

Wide Track and Maxxis® Tires: Wheels are set motocross-spec wide, near the allowable maximum of 50 inches, for great cornering speed. Maxxis® tires provide excellent handling and control. At 20 inches in the rear and 21 inches in the front, they provide better ground clearance than the competition.

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.

Wide Footpegs: The generous 2.6 inch-wide foot pegs are something riders will appreciate every time they want to get up on the pegs.

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.

Long A-Arm Suspension: The front frame is as narrow as possible at the A-arm mounting points. This increases the A-arm length and reduces changes in camber as the suspension travels through its full range of motion.

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.

Swingarm Rear Suspension: The rear swingarm is crafted of strong, gravity-fed aluminum and is matched to a fully adjustable 46mm KYB® piggyback shock for excellent handling. For comfort even on tough terrain, the rear wheel offers 11.0 inches of travel.

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.

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

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.
