2025 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.
Features May Include:
- 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 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 & 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. - 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 feeling right off idle. The high compression ratio further improves overall engine performance. - Fuel Injection

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 & 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. - 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 & 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 Kashimaâ„¢ 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. - 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.
