2014 Yamaha YZF R1

GREAT SOUNDING TWO BROTHER'S EXHAUST!!! 2014 Yamaha YZF-R1THE SUPERBIKE CHAMPION.With back-to-back Superbike Championship in 2011 and 2012 and packed with MotoGP technology, the YZF-R1 is the most advanced Open Class sportbike on the planet. And unlike anything else. That's because it's the world's first production motorcycle with crossplane crankshaft. Resulting in incredibly smooth power delivery and outrageous torque for a rush like never before. From the track to the street, the R1 truly is "the 1." Key Features May Include: The YZF-R1 benefits from MotoGP® technology - a seven-level Traction Control system. The system has been developed so the rider does not feel any unnatural or harsh intervention from the system. In addition, traction control can aid in reducing tire wear due to less wheel spin. Coupled with the three level D-Mode electronic throttle response control, riders have 21 different choices available to tailor the YZF-R1 to their riding preference. This R1 keeps all the technological superiorities developed for its predecessor: YCC-T® (Yamaha Chip Controlled Throttle) is a MotoGP® inspired fly-by- wire technology used to deliver instant throttle response. YCC-I® is Yamaha Chip Controlled Intake which is a variable intake system that broadens the spread of power. The fuel injection system provides optimum air/fuel mixtures for maximum power and smooth throttle repsonse. 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 lightweigt Controlled-Fill die-cast magnesium, contributing the optimum mass centralization. Suspension includes YHSJ (Yamaha Hydraluic System Japan) 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 rebound damping. And the rear shock adopts bottom linkage for optimum suspension characteristics. The sound on the YZF-R1 is unlike any other inline-four cylinder production supersport. The precise and throaty pulse of the exhaust note will have riders enthused every time the thottle is opened. Crossplane crankshaft technology proven in victory after victory on MotoGP® machines provides a high-tech uneven firing interval. Unlike typical inline-four engine design, where the two outer and two inner pistons move together in pairs with 180°intervals, the crossplane crankshaft has each connecting rod 90° with a unique firing order of 270° –180° – 90° – 180°. This overcomes the inherent fluctuations in inertial torque during each engine revolution, and the accompanying peaky torque characteristics. Instead, combustion torque continues to build, giving the rider more linear throttle response with awesome power and traction out of the corners. Seven-level Traction Control System allows the rider to get more traction and drive while exiting corners. 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. The frame has a combination of uncompromising rigidity where needed along with carefully achieved flex for the precise rigidity balance this bike needs to give the rider the full benefit of its handling and engine characteristics. It is a sophisticated combination of Controlled-Fill die-cast, stamping, and gravity casting… the exact technology needed for each portion of this advanced frame.
