Yamaha’s all-new 189 bhp, US$11,600 YZF-R1 Supersport

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.
