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, [Cite_web|title=New Yamaha R6 Does Not Rev To 17,500 rpm After All|url=http://www.motorcycledaily.com/01february06_redline.htm|work=Motorcycle Daily|author=Alex Edge|date=2006-02-01|accessdate=2006-02-15] and offered to buy back any R6 if the customer was unhappy.
