2025 Yamaha YFZ450R
CHAMPIONSHIP COLLECTORBoasting podium-topping DNA and serious racing pedigree, this is the unmatched, race-ready Sport ATV for those who want to win.
Features may include:
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 feeling right off idle. The high compression ratio further improves overall engine performance.
- Fuel Injection
The YFZ450R 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.
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 & 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.
