| 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 chassis 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.
New five-spoke wheels reduce unsprung weight by making
hub and spokes a single structural unit. The new casting
technique makes the rim lighter, not to mention wickedly
cool-looking.
The ultra-compact, lightweight, 600cc, DOHC, 16-valve,
liquid-cooled in-line four-cylinder engine puts out
over 200 horsepower per liter. The engine retains its
long-stroke dimensions for excellent midrange torque,
but over 90% of its parts are stronger or lighter, including
the new forged pistons and the new sleeveless cylinders.
For 2003, the second-generation R6 benefits from the
addition of the same type of suction-piston fuel injection
as the R1. The R6's voracious appetite for air has been
optimized to work with its new fuel injection, that
utilizes a larger pressurized airbox, bigger throttle
bodies, and resculpted intake ports. Yamaha's suction-piston
fuel injection system gives unsurpassed throttle response.
New dual Gatling beam multi-reflector headlights produce
bright, even lighting, and are enclosed in a redesigned
fairing for superb aerodynamics.
The result of all these changes is more power, less
weight (now 8 lbs. lighter), and a clearer dialogue
between man and machine.
