With
a complete design update in 2002, the YR1 for 2003 remains unchanged,
avaialble in team race colors Bue/White, Red/White, and Silver &
Black as shown. The big change is the all-new YZF-R6.

2003
YZF-R1
Now in its second year and still sharing center stage in the 4-cylinder
open class with Suzuki's GSXR1000, the YZF-R1is a motorcycle that represents
just how far Yamaha has come inrefining their 20-valve, Deltabox III-framed
R1 into the rippingest two-wheeled conveyance ever released on planet
Earth. The worldwide media has tripped all over itself heaping praise
upon the R1 ever since its introduction, including being named
Sport Rider magazine's Bike of the Year not once, but twice. Yamaha's
unique suction-piston fuel injection marries modern fuel injection with
vacuum-slide carburetor simplicity to produce the most seamless throttle
response in the business. Forty-millimeter throttle bodies keep all
12 intake valves well-nourished all the way to redline. The exhaust
head pipes and muffler are titanium, and contain a catalyst as well
as our patented EXUP system for a crisp, clean burn.
The R-1's Deltabox III frame embraces the engine as a stressed piece
of the frame, making the whole stronger than the sum of its parts. Made
up entirely of castings, this breakthrough hunk of metallurgical artwork
uses just two welds, unlike the 16 on the frame a generation before.
Stacked transmission shafts keep the engine short and allow use of an
unusually long swingarm, even within the confines of the class' shortest
wheelbase.

YZF-R6 Information
The all-new YZF-R6 for 2003 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.
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.
