Yamaha's YZF-R6 is a 600 cc sport bike, first introduced in 1999, updated in 2001, 2003, 2006 and revised in the years in between. The current version (model year 2007) has a 357 lb (161 kg) manufacturer claimed dry weight and delivers 112 hp.[1]

[edit] Competition
The R6 competes with other middleweight sport bikes that include the Ducati 749, Honda CBR600RR, Kawasaki Ninja ZX-6R, Suzuki GSX-R600, and Triumph Daytona 675.
[edit] Controversy
In 2006, Yamaha advertised the R6 as capable to running at up to 17,500 rpm. This is 2000 rpm higher than the previous R6 model and it is the highest redline of a widely distributed production four-stroke engine – the Honda CBR250RR had a reputed redline of 18,500 rpm but was originally distributed only in the Japanese market. Such a high speed is near to levels known only in Formula One engines, where valve springs stress problems lead to the adoption of pneumatic return at more than 19,000 rpm.[2]
But it was widely reported that the 2006 YZF-R6's motor did not have this redline level and was closer to around 16,200 rpm, because of a tachometer error of about 9%. In February 2006, Yamaha admitted the bike's true redline was more than 1,000 rpm lower than advertised,[3] and offered to buy back any R6 if the customer was unhappy.[4]
This is not the first time a sportbike's true redline has differed from its redline shown on the tachometer. The 2005 Kawasaki Ninja ZX-6RR has an indicated redline of 16,500 rpm on its tachometer. However, during a SportRider magazine test in the fall of 2005 when testing the ZX-6RR on a dynamometer it wasn't possible to get the motor to rev past 15,000 rpm. The tachometer on most sportbikes is off by a certain percentage. New 600 cc motorcycles are revving up higher and higher, and while the percentage of tachometer error might not change, the error in number of RPMs increases.
