Is it the Handling? The Horsepower? Or the Looks? The all-new YZF-R6 begins with a radical new DeltaBox III frame. The first street motorcycle ever to use our new Controlled Filling Die Casting technique, resulting in a lighter aluminum frame that's stiffer. What once took 16 welds now requires two. Revisions to the steering head give even greater feedback. And a 10mm longer swingarm and repositioned swingarm pivot improve traction.
