Back for 2011, the Yamaha YZF-R1 is the only production motorcycle with a crossplane crankshaft. Crossplane technology, first pioneered in MotoGP racing with the M1, puts each piston 90-degrees from the next, with an uneven firing interval of 270-180-90-180.
This uneven order does an amazing thing for this motorcycle, it actually lets power build more smoothly. That means smooth roll-on delivery out of the corners, with outstanding tractability, followed by very strong high rpm power. As Valentino Rossi said, this is the "sweet" power.
The 2011 Yamaha R1 keeps all the technology developed for its predecessor: YCC-T (Yamaha Chip Controlled Throttle) is 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 R1 features Yamaha D-MODE (or drive mode) with rider-selectable throttle control maps to program YCC-T performance characteristics for riding conditions. The standard map is designed for optimum overall motorcycle performance.
The rear frame is lightweight Controlled-Fill die-cast magnesium, contributing the optimum mass centralization.
The 2011 R1 suspension includes SOQI front forks which use one of the tricks developed for the 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.
