Product description

Designed to dominate the race track, the YFZ450R is sure to draw many checkered flags.

With a "wide-track" chassis and long travel suspension, the 450R provides incredible stability, confidence and control. The powerful 5-valve 449cc race engine is fuel injected with many components developed from our motocross bikes including the cylinder, cylinder head, cams and crank designs. .The engine is cradled by a hybrid aluminum chassis for optimized strength and rigidity, making the YFZ450R the most capable racer we've ever developed.

Fuel Injected 4-Stroke Engine: Dual Over Head Cam (DOHC) 449cc 4-stroke engine retains a 5-valve head for optimum high RPM power. Many of this engine's design elements have come directly from our race winning YZ motocross bikes, including the cylinder, cylinder head, cams and crank. Engine power and mid-range response are both improved over the carbureted YFZ and with Yamaha fuel injection, engine power is always optimized, regardless of altitude or temperature. Engine durability was improved over the old carb versions as well with beefed up crankcases, a large diameter big end crank bearing, stronger connecting rod and a smoother counter balancer.

Yamaha Fuel Injection: Yamaha Fuel Injection (YFI) uses a 12-hole injector that provides exceptional atomization of the fuel for maximum combustion efficiency and power delivery. The system also uses a big, 42mm Mikuni throttle body and includes ISC (Idle Speed Control) for easy, reliable start-up and warming. YFI constantly monitors variables such as air temperature, intake pressure, engine temperature, throttle position and more, to ensure optimum fuel delivery. YFI automatically compensates for changes in temperature, elevation, and even barometric pressure. This means you don't have to fool with carburetor jetting, so you can focus on the ride.

Hybrid Aluminum & Steel Frame: The frame is designed of lightweight aluminum, with a tension-steel bottom frame that lets the engine sit lower for excellent mass centralization. The lower frame is made from strong high tensile steel, since that portion typically takes the majority of abuse from rocks and debris. This hybrid frame also incorporates a "Zero Weld" design for maximum strength.

Wide Track Chassis: For ultimate track handling and stability, the YFZ450R is 3-inches wider than the YFZ450 X. The front a-arms incorporate the "Wide Arc" design to greatly improve ground clearance, so obstacles are less likely to impact the lower a-arms. Upper and lower a-arm pivot points are positioned close together to reduce the pivot angle and improve suspension control.

High Tech Long Travel Suspension: The suspension geometry allows for long travel front shocks with 9.8" of front suspension travel. Piggy-back reservoir front shocks are robust with 44mm rods and a Kashima coating for reduced friction. In the rear there's a long cast aluminum swing-arm serving up 11" of travel from a long-travel fully-adjustable piggyback shock. All three shocks (front and rear) have high and low compression, rebound and threaded pre-load adjustments enabling you to tune the ride to the conditions.

Spacious and Comfortable Ergos: A wide-back seat provides the perfect balance between comfort and movement. It's narrow in the front for easy transitions from side to side, but wide in the back to help cushion the landings and rough corners. And even though the YFZ R has long suspension travel and a race oriented seat design, seat height remains at a low 31.9".

Racing Controls: ProTaper handlebars are mounted on 4-way clamps for exceptional adjustability. There are two sets of holes in the handlebar crown, and eccentric clamps so the rider can choose the standard setting, 10mm or 20mm forward, or 10mm back. The thumb throttle is designed to minimize effort. The front flip-type parking brake is removable for racing. The front brake lever is adjustable and the clutch lever is adjustable on the fly.
