Yamaha YZF-R description

2011 Yamaha YZF-R1, Yamaha has revealed the official details on the 2011 YZF-R1, the only production motorcycle with a crossplane crankshaft. The 2011 YZF-R1 is powered by a 998cc, DOHC, 4-valve, in-line 4 engine developing 182 hp at 12500 rpm and 115.5 Nm (85 lb.ft.) of torque at 10,000 rpm, and delivering a fuel consumption of 40mpg (5.88 l/100km).The engine features forged aluminum pistons that take maximum advantage of the power characteristics. Titanium intake valves are lightweight. A forced-air intake system is adopted to increase intake efficiency by using the natural airflow during riding to pressurize the air in the air box. This contributes to outstanding power delivery characteristics in the high-speed range, while the design also helps to minimize intake noise.For 2011, the side fairing is smooth for a sleek appearance. And, instead of the usual four-bulb headlight design, the R1 has only two projector-type bulbs mounted closer to the nose of the bike. This positions ram air ducts closer in for a more compact, smooth look. In addition, the rounded lenses are unique to the supersport industry.In keeping with this machines exceptional cornering ability and crisp handling, the aluminum frame has been designed to offer exceptional rigidity balance. The rear frame is lightweight Controlled-Fill die-cast magnesium, contributing the optimum mass centralization. Suspension includes SOQI front forks which use one of the tricks developed for our winning MotoGP bikes: independent damping. The left fork handles compression damping and the right side handles the rebound damping. And the rear shock adopts bottom linkage for optimum suspension characteristics.The bike is now on sale at a price of $13,590.Read more: :// /motorcycles/motorcycle-reviews/yamaha/2011-yamaha-yzf-r1-ar101088.html#ixzz2WiowMveE
