Advanced air management
As we have already described
in the previous ‘engine’ section, Yamaha’s engineers have focused a large
proportion of their attention on intake air volume in order to achieve
increased performance. To maximise the benefits of the YCC-I and YCC-T – as
well as the new high-compression 4-valve head design – the R1’s front cowl has
been completely redesigned.
The layered structure of the
new cowl has been specifically designed to reduce air resistance and increase
the flow of intake air, and in doing so it helps to increase the intake air
volume – a key factor in achieving the increased performance of the new R1
engine.
The cowl’s layered structure
increases the speed of the air flow over the bodywork, and this creates a
negative pressure in the mass of hot air surrounding the engine. This negative
pressure effect causes the hot air to be drawn away from the engine, thus
ensuring that the new R1 delivers consistently high levels of performance
during sustained high rpm use.
Muscular new bodywork
Since the launch of the
first R1, this iconic machine’s athletic and aggressive bodywork has always set
the standard for style, functionality and presence.
The new 2007 model takes all
three aspects to a new level, and the muscular new body design successfully
reflects the fifth-generation R1’s even greater engine and chassis potential.
As with every previous
generation of this outstanding supersport bike, the new R1’s bodywork is bold
and innovative, while still maintaining the instantly-recognisable R1 genetic
make up.
Finely-defined edges convey
a truly dynamic feel, and the wide air intake has been deliberately designed
with a look that accentuates its actual function of drawing in greater volumes
of air to boost engine performance – while the new 2-eye 4-bulb headlights give
the bike an unmistakeable R-series face.
At the rear there is a
compact new tail assembly and newly designed seat, as well as a new LED tail
light and separate mudguard with license plate holder – and the double
underseat mufflers form a ‘V’ configuration for a distinctive looking rear end.
Other features
The other notable features
on the new R1 include a newly designed front-rear two-part ‘covered top’ fuel
tank as well as new instrumentation with a needle type tachometer and digital
speedometer. And to handle the increased performance a new twin fan radiator is
fitted.

Superbike racing programme
In addition to the
technology transfer from our winning MotoGP machinery, Yamaha successful World
Superbike (WSB) racing activities have also been of great benefit to the
R-series development programme. In the first half of the 2006 season our
factory-supported R1 superbike racers have proven to be amongst the leading
contenders in WSB, with a series of podium finishes.
