The 2009 R6
getsnew colour schemes! and it also gets a remapped engine control unit (ECU),
which has revised YCC-T settings for optimized power delivery. Expect smoother,
more linear power when exiting medium- to high-speed bends on your R6. And the
machine’s brilliant top-end performance has also been kept intact.
Apart from the black, blue/white and red/white paintjobs, the 2009 YZF-R6 is
also available in US-spec orange and white.
2008 R6 Review
The razor sharp handling of last year's R6 blew us
away, but it was let down by an engine that lacked power at real world rpm
levels. For 2008, Yamaha introduces an all-new R6 that addresses this problem
with a variable intake system first introduced on the 2007 R1 (a computer
controlled intake tract length). Yamaha calls this YCC-I for Yamaha Chip
Controlled Intake.
The new R6 features plenty of other new technology, as well. The bike is more
than substantially upgraded, with changes to the engine, chassis, suspension and
brakes.
The new engine not only has the ability to vary the intake length to aid both
low rpm power and high rpm breathing, Yamaha revised the pistons and increased
compression from 12.8-to-1 to 13.1-to-1. This should also improve torque down
low. To further increase power, Yamaha attacked friction within the engine.
Yamaha claims over 50 new friction-reducing changes in the 2008 R6 motor,
including the use of wider crank bearings.
The fly-by-wire throttle system, already available on the prior R6 is claimed to
be enhanced with improved fuel injection mapping.
Top to bottom - frame, swingarm,
and subframe
The 2008 R6 has an all-new frame with a thicker head pipe/headstock area, and
swingarm pivot intended to improve balance that leads to more precise turn-in
and increased corner speeds.
Working with the new frame is a new swingarm featuring internal ribs that aid
the rigidity Yamaha was seeking while minimizing weight.
Speaking of weight, Yamaha took the rather extreme step of constructing its
subframe (the structure supporting the seat) out of magnesium for 2008 -- a
rather exotic and expensive material that can form very strong but light
structures.
A new titanium muffler contains an EXUP valve system to further broaden the
powerband of the new R6. The new exhaust is also designed to meet ever
tightening emissions regulations.
Yamaha claims that the already outstanding feedback provided by the current R6
is improved for 2008 in part by revised fork tubes and a new triple clamp design
with increased fork off-set.
A slipper clutch on the new R6 helps control wheel hop on agressive downshifts.
Both the 41mm fork and rear shock feature four-way adjustability (preload,
high-speed compression, low-speed compression, and rebound damping).
The new bodywork on the 2008 YZF-R6 is claimed to improve aerodynamics, both on
the street and on the track.
New front brake discs are thicker (5mm vs. 4.5mm last year) to improve cooling.
They are squeezed by forged one-piece, radial mount calipers powered by a
radial-pump master cylinder.
The dry weight of the new 2008 R6 is actually a few pounds higher than last
year's claimed dry weight -- probably related to emissions systems contained
within the exhaust.
