2011 YFZ450R and YFZ450X sport ATVs, completing the industry's strongest sport ATV line-up for the coming year. With superior power, comfort and handling, Yamaha's high-revving YFZ450R and 450X are specifically designed for pure performance and get new color and graphics in 2011.
Both the YFZ450R and X have proven Yamaha performance and durability with long-travel adjustable suspension, a no-weld aluminum with steel hybrid frame, and a powerful fuel injected engine.
The YFZ450R is a motocross-ready ATV at 48.8 inches wide. Mike Martinez (Yamaha ATV and Side-by-Side Vehicle Group General Manager) says: "Yamaha started the high-performance 450 sport ATV class with the original YFZ450, and we continue to dominate this class with the best options no matter where you race or ride. Both Yamaha models have powerful 5-valve DOHC liquid cooled single cylinder 449cc engines. The 2011 YFZ450R and YFZ450X both come in Team Yamaha Blue and White for $8,599.
Yamaha reshaped motocross in 2010 with the introduction of its radical YZ450F, but for 2011 the silence from the blue camp is just as impressive. Instead Yamaha simply expanded the fuel tank 200cc for a total capacity of 1.64 gallons (though it was the CRF race bikes that ran out of fuel this summer). The other change is a reshaping of the clutch actuation arm which has a slightly different cam shape and is 6mm longer.
