Yamaha has revealed the official details of the 2011 YZF-R1, the only production motorcycle with a cross plane crankshaft. The 2011 YZF-R1 is powered by a 998cc, DOHC, 4 valve, 4-in-line engine developing 182 hp at 12,500 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 has forged aluminum pistons to take maximum advantage of the power features to take. Titanium intake valves are lightweight. A forced-air intake system is adopted to increase intake efficiency by using the natural airflow during riding to the air pressure 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 shell side is smooth for a clean look. 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. These positions ram air ducts closer in for a more compact, smooth look. In addition, the round lenses are unique to the supersport industry.

The rear frame is lightweight, Controlled-Fill die-cast magnesium, contributing the optimum mass centralization. SOQI suspension fork that includes one of the tricks developed for our winning MotoGP bikes ® use: independent damping. The left fork handles compression damping and the right side provides the rebound. And the rear shock will bottom coupling for optimum suspension characteristics.
The bike is now for sale at a price of $ 13,590.
