Spies Explains the R1
Click video to learn more about the 2009 Yamaha YZF-R1 that Ben Spies piloted in the 2009 World Superbike Championship. The 2009 YZF-R1 is 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 uneven order does an amazing thing.
The power actually lets power build more smoothly. That means smooth roll-on delivery out of the corners, with outrageous amounts of torque, followed by very strong high rpm power. 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.
This next-generation R1 keeps all the technological superiorities 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 fuel injection system provides optimum air/fuel mixtures for maximum power and smooth throttle response.
