In the supersport liter class, there’s always lots of talk about power. You expect that. What you wouldn’t have expected – until now – is a radically superior way to deliver that power. Introducing the 2009 YZF-R1, the first ever production motorcycle with a crossplane crankshaft. Crossplane technology, first pioneered in MotoGP racing with the M1, puts each connecting rod 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°. This all but eliminates undesirable inertial crankshaft torque, which allows the engine’s compression torque to build smoothly and provide a very linear power delivery out of the corners. It’s a feeling that’s simply unmatched, like having two engines in one: the low-rpm torquey feel of a twin with the raw, high-rpm power of an inline 4. In fact, the new YZF-R1 is not a continuation of existing supersport development; it is breakthrough technology that represents a paradigm shift in both technology and performance.
