Image 16 of 18 from Yamaha’s all-new 189 bhp, US$11,600 YZF-R1 Supersport

October 17, 2006 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.
