Yamaha YZF-R description

2012 Yamaha YZF-R1, The 2012 Yamaha YZF-R1 is powered by a 98cc, liquid-cooled 4-cylinder DOHC 16-valve engine with titanium intake valves. Unique to Yamaha is the crossplane crankshaft technology that has proven to be a home-run technology for Yamahas MotoGP machines. Unlike typical inline-four engine design, where the two outer and two inner pistons move together in pairs with 180intervals, the crossplane crankshaft has each connecting rod 90 with a unique firing order of 270 180 90 180. What this does is overcome 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. A forced air intake system is also part of the whole set-up, increasing the engines intake efficiency by using the natural airflow during riding to pressurize the air in the air box. This, in turn, contributes to the bikes power delivery characteristics in the high-speed range, while the design also helps to minimize intake noise. The bikes fuel-injected engine also takes full advantage of Yamahas YCC-T technology, the MotoGP-inspired fly-by-wire technology thats used to deliver instant throttle response. The YCC-T combines with the YCC-I variable intake system that broadens the spread of the bikes overall power.For 2012, the YZF-R1 receives another benefit from MotoGP technology a seven-level Traction Control System. The system has been developed so the rider does not feel any unnatural or has intervention from the system. In addition, traction control can aid in reducing tire wear due to less wheel spin and when you couple that with the three level D-Mode electronics throttle response control, you have a bike that offers 21 different choices available to tailor the YZF-R1 to their riding preference.
