2011 YAMAHA YZF-R1, THE BARK IS BAD, THE BITE IS BADDER Forget everything you ever knew about the super sport liter class. The all-new YZF-R1 is unlike anything before. That⿿s because it⿿s the world⿿s first production motorcycle with a crossplane crankshaft. The result? Incredibly smooth power delivery and outrageous torque for a rush like you⿿ve never experienced.
