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

October Yamaha’s all new 2007 YZF-R1 Supersport machine hits showrooms in a few weeks time and the new bike is bristling with innovative technology, including the world’s first variable air funnel intake on a motorcycle. The YCC-I (Yamaha Chip Controlled Intake) electronically varies intake length to maximise combustion efficiency at all rev levels and so produce a more linear power curve. The new R1 also sports ‘fly-by-wire’ throttle first used on Valentino Rossi’s world championship winning YZR-M1 race bike. The YCC-T system (Yamaha Chip Controlled Throttle) senses a rider’s accelerator operation and an ECU instantly calculates the optimal throttle opening to provide instant response and smooth power in every situation. These high tech features combine with a strong four-valve engine to produce an astonishing 189 bhp (139 kw) @ 12,500rpm with ram air effect. Power is transmitted to the tarmac via a race-style slipper clutch and once the power gets there, a pair of six piston radially mounted front brake calipers ensure the rider is always in control. A fifth generation ‘controlled flex’ aluminium chassis and swingarm further improves stability and handling, while futuristic styling incorporating advanced air management reduces air resistance while boosting intake for maximum performance.

Shaped by Yamaha’s Art of Engineering

More than any other motorcycle, the all-new Yamaha R1 embodies the dynamic and exhilarating spirit that today’s experienced supersport rider demands. Ever since the introduction of the first generation model in 1998, the R1 has consistently exceeded the expectations of supersport riders all over the world. And by applying our legendary Art of Engineering concept to the new engine, chassis and bodywork, we have created a remarkable new machine which is ready to reinforce Yamaha’s reputation as the leading manufacturer of high-performance motorcycles.

Yamaha have always placed great emphasis on the importance of the man-machine relationship, and with this as our guiding principle, we have developed a new fifth-generation R1 which showcases a whole range of advanced new technology.

New R1: Advancing the man-machine relationship

Today, much of the focus in supersport machine development is on computer control, and Yamaha is at the forefront of this exciting new technology.

However, we have never believed in the use of technology for technology’s sake. When Yamaha develop new technologies, our aim is always to enhance the man-machine relationship, which is ultimately what makes a motorcycle so different from any other form of transport.

From our perspective, the needs and desires of the rider will always come first, and so whenever we develop new technology, it must not only offer a real performance advantage to the rider, but also enhance the overall riding experience. This is exactly what our ‘Art of Engineering’ is all about, and it is this way of thinking that enables Yamaha to create some of today’s most innovative, exciting and remarkable new models.
