2011 Yamaha YFZ450R
The 2011 Yamaha YFZ450R is a pure bred race machine. With a fuel injected 449cc 5-valve engine, an incredibly strong hybrid chassis with motocross-wide-track stance and super premium triple adjustable long travel suspension, the 2010 Yamaha 450R was made for the motocross track.
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 YFZ450R provides incredible stability, confidence and control. The poerful 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 5-valve 4-stroke race engine
Lightweight Aluminum Frame
Awesome power comes from a fuel-injected 449cc, 4-stroke, 5-valve, DOHC engine, spinning optimum high RPMs. This YZ-inspired engine tuned to boost low- and midrange power for arm-straightening drive out of corners.
A compression ratio of 11.6:1 and optimizing port shapes help the YFZ450R make maximum power. Stout bearings and connecting rod add even more strength and reliability.
Yamaha’s Fuel Injection uses a 12-hole injector to provide exceptional atomization of the fuel for maximum combustion efficiency and power delivery. Idle Speed Control (ISC) and the large 42mm Mikuni® throttle body delivery easy, reliable starting, and continually monitor air temperature, intake pressure, engine temperature, throttle position and more, to ensure the right fuel delivery. So fiddling with the carburetor jetting is a thing of the past, all you have left to do is focus on the ride.
Lightweight Aliuminum Frame
The no-weld cast aluminum frame is light and strong, providing solid groundwork for the front and rear suspension systems. The wide track helps the YFZ450R achieve amazingly flat and precise cornering.
Wide Arc Design
The front a-arms “Wide Arc” design makes room for awesome ground clearance. The upper and lower a-arm pivot points are positioned close together to reduce the pivot angle to improve suspension control.
9.8 inches of front wheel travel, controlled by 44mm fully adjustable KYB shocks with Kashima coating, means precise handling and a smooth ride.
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.
Easily replaceable panels in high wear areas will provide flex and grip for aggressive riding.
Exclusive 20″ Rear Tires
20″ rear tires offer extra ground clearance and the best all-round performance for track and trail.
Super Wide Foot Pegs
65mm wide foot pegs help ensure your feet have traction when you need it.
” LED tail light for improved visibility, longevity and reduced electric power consumption.
” Wave rear brake rotor for less unsprung weight
” The new throttle lever requires less effort, and it’s very comfortable to use. That means less fatigue during all-day riding.
” The instrumentation is all business. 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 a straightforward LED display.
