This is 2500 rpm higher than the previous R6 model and it is the highest redline of a widely distributed production [[Four-stroke|four-stroke]] engine (the [[Honda CBR250|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 led to the adoption of pneumatic return at more than 19,000 rpm. | ||
But it was widely reported that the new 2006 YZF-R6's motor did not have this redline level and was closer to around 16,200 rpm. 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. | But it was widely reported that the new 2006 YZF-R6's motor did not have this redline level and was closer to around 16,200 rpm.
