2019 Yamaha YFZ450R

The YFZ450R boasts podium-topping DNA and a serious race pedigree. Which begs the question: How big is your trophy case?

• Engine

The fuel-injected 449cc engine has superb power characteristics. Power delivery is smooth and strong off the line with lots of midrange to top-end power.

The 449cc engine uses a five-valve cylinder head and titanium valve technology designed 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.

The YFZ450R incorporates Yamaha Fuel Injection 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

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

The wheels have been designed with the inner lip rolled in. This increases the rigidity, allowing a reduction in weight while maintaining strength.

Wheels are set motocross-spec wide, near the maximum allowable 50 inches, for great cornering speed. Maxxis® tires help 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.

• Additional

The throttle lever requires low effort for less fatigue during long motos.

The discrete 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.
