Yamaha R1: The ultimate supersport bike?



Reviews imageFeaturing an all-new engine, chassis and bodywork, the 2007 R1 can justifiably claim to be the most sophisticated high-tech supersport machine ever built. And, at the same time, it delivers the most exciting, rewarding and responsive riding experience imaginable. 

Ever since the introduction of the first generation model in 1998, the R1 has consistently exceeded the expectations of supersport riders. Today, much of the focus in supersport machine development is on computer control, and Yamaha is at the forefront with YCC-T (Yamaha Chip Controlled Throttle) which has played a pivotal role in making the new-generation YZF-R6 today’s leading 600 supersport. 

For 2007, Yamaha introduced YCC-I (Yamaha Chip Controlled Intake), the latest innovation in electronic intake control which is designed to raise the performance of the R1 to a new level. 

Riding around town at lower rpm, thanks to YCC-I the 998cc engine is operating with its long 140mm intakes, which give strong torque and excellent throttle response. And once the rider increases the engine speed and throttle opening on fast highways or when circuit riding, the intake length is instantaneously reduced to 65mm, allowing the engine to reach its full potential. 

Producing 180PS at 12,500rpm (not including direct air induction), the new fifth-generation R1 is the most impressive and powerful R-series motorcycle ever produced. 

The 2007 R1 also gets a slipper clutch. This system shares the same structure as that found on the limited-edition 2006 YZF-R1SP model, and is designed to limit the amount of back-torque transmitted from the rear wheel through to the crank. 

Externally this new frame appears similar to the 2006 design, but it is has been completely redesigned, and offers a totally revised rigidity balance which matches the increased performance potential of the new engine. 

Complementing the all-new Deltabox frame is a newly designed swingarm which features an asymmetric left/right layout, and consists of an upside-down truss configuration.
