Yamaha YZF-R6

Yamaha's YZF-R6 is a sport bike, first introduced in 1999, updated in 2001, 2003, 2006, 2008 and revised in the years in between. The 2007 model has a tested dry weight and delivers a tested at 14,200 rpm and at 11,500 rpm.

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 19,000. 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.

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, and offered to buy back any R6 if the customer was unhappy.
