This model adopts Yamaha’s new “YCC-I” electronic control
intake, which has been developed under Yamaha’s G.E.N.I.C.H. engineering
ideal using exclusive electronic control technologies and is now put to
practical use to boost engine performance. Another new feature is the
lightweight magnesium rear frame made possible by a unique Yamaha technology
and adopted for the first time ever on a production motorcycle. By
contributing to greater concentration of mass it helps realize the next
level of sport riding performance
The 2006 model YZF-R6 featured a high-performance engine
adopting for the first time the “YCC-T” (Yamaha Chip Controlled Throttle)
based on Yamaha’s G.E.N.I.C.H. engineering ideal and was released as “the
extreme supersport fastest on the circuit.” Ever since, it has won great
popularity on the European and North American 600cc supersport markets. The
reasons for its popularity are its acceleration in the over 10,000 rpm
range, smooth power development and response, light, agile cornering, smooth
operability and unique styling. At the same time, as the market has
expanded, there have been many calls for even higher levels of running
performance while maintaining the same original model concept.
In light of this market background, the new YZF-R6 has been
developed around the new concept of “an R6 that is No. 1 in laser-sharp
handling and super-exciting performance.” Under this concept, the
existing circuit performance and performance on secondary and winding roads
has been supplemented by (1) added excitement in circuit riding, (2)
handling that lets the rider enjoy quicker banking and turning and more
agile exiting of turns and (3) new developments in original styling that
maintains the YZF-R6 identity. This model also adopts new technologies for
greater product maturity, including Yamaha’s new “YCC-I” electronic control
intake and the first lightweight magnesium rear frame ever adopted on a
production motorcycle. These features further boost running performance.
Key Features:
Light, powerful and bristling with knowledge gained from years of
racing, the YZF-R6 is the most advanced production 600cc motorcycle
Yamaha—or anybody else—has ever built.
The YZF-R6 was the first production motorcycle with a fly-by-wire
throttle system—for flawless response under all conditions.
YCC-I, Yamaha Chip Controlled Intake, introduced in 2007 on the R1, is
now used on the R6 to vary intake tract length for excellent cylinder filling
and a broader powerband. On the higher-revving R6, its benefits are even
more pronounced.
Slipper-type back torque-limiting clutch greatly facilitates
braking/downshifting from high speed.
New for 2008:
Over 50 friction-reducing strategies have been employed inside the
engine, including the use of wider crank bearings.
Upgraded fuel injection mapping for the YCC-T dual-injector system
complements the higher compression ratio for great throttle response and
reduced engine braking.
A magnesium subframe removes weight from the rear of the motorcycle
for increased mass centralization.
All-new frame takes handling to the next level, allowing more precise
turn-in, greater corner speed, and tighter exits. Thicker
headpipe-headstock and swingarm pivot area walls, and elimination of the
frame crossmember, help achieve perfect balance.
New swingarm has internal ribs added, and extruded section is now
forged to work with the new frame.
Revised outer fork tubes, a new lower triple clamp, and increased fork
offset provide highly tactile front-end feedback.
Moving the rider and bars forward and slightly lower enhances braking
and turn-in performance. Clip-ons are also lower and re-angled.
Front discs are 310 x 5mm instead of 4.5mm for increased cooling
qualities.
Increased fork height adjustability and rear ride-height adjustment
range accommodate a greater range of riders and tires.
Revised bodywork results in even greater aerodynamic efficiency.
Engine:
YCCT—Yamaha Chip Controlled Throttle—uses a powerful ECU and multiple
sensors to provide perfect, smooth engine response and optimal power
whenever the throttle is twisted under all conditions.
Twin-injector fuel injection: shower-type injectors above each intake
funnel help achieve optimum fuel atomization at high rpm.
Back torque-limiting slipper clutch greatly facilitates braking and
downshifting from high speed. Close-ratio six-speed transmission delivers
seamless power and maximum acceleration.
GP-style titanium muffler contributes to mass centralization and
contains EXUP for a broad powerband, spot-on injection and emissions
compliance.
Linerless, direct-plated ceramic-composite cylinder bores mean greater
heat dissipation for consistent power delivery and reduced friction.
Cool magnesium valve and engine covers are light and stylish.
Deltabox aluminum frame incorporates GP thinking in terms of engine
positioning and rigidity for the ultimate in 600-class handling.
Light, Controlled-Fill swingarm pivots high in the frame, for
increased anti-squat effect and mid-corner stability. TZ-type chain
adjusters ease rear tire changes.
Four-way adjustable (preload, high-speed compression, low-speed
compression and rebound damping) inverted fork with 41mm tubes increases
freedom in setting up for street or track use; soak up the bumps and
resist bottoming when braking.
Four-way adjustable (preload, high-speed compression, low-speed
compression and rebound damping) piggyback rear shock delivers exceptional
rear wheel tracking and stability.
Dual 310mm front disc brakes use forged one-piece radial-mount
calipers and radial-pump front master cylinder with adjustable lever for
astounding braking power and feel.
The casting technique for the five-spoke 17-inch wheels makes the rims
light and strong, not to mention wickedly cool-looking.
Additional Features:
Quick-detach license plate holder and rear turn signal mount makes
prepping for track days or racing a snap.
Built-in lap timer is controlled by a right handlebar switch.
Multifunction digital and analog instrumentation features:
programmable shift light, digital speedometer, analog tachometer, dual
tripmeters with miles-on-reserve function, odometer, water temp gauge and
lights for neutral, high beam, low fuel and turn signals.
