Yamaha's YZF-R6 is a 600 cc (37 cu in) sport bike, first introduced in 1999, updated in 2001, 2003, 2006, 2008 and revised in the years in between.

Controversy

2006 R6

In 2006, Yamaha advertised that the R6 had a redline of 17500 rpm. This is 2000 rpm higher than the previous R6 model and was the highest tachometer redline of any 2006 production four-stroke motorcycle engine.

Hypothetically, if it was the actual engine RPM, it would be at levels previously known only in Formula One engines, where valve spring stress problems lead to the adoption of pneumatic valve actuation to handle more than 19,000 rpm.

It was widely reported that the 2006 YZF-R6's motor did not have this engine rpm redline level and was closer to around 16200 engine rpm, but because of a deliberate tachometer error of about 9%, it read 17,500 tachometer rpm. In February 2006, Yamaha admitted the bike's true engine redline was more than 1000 rpm lower than displayed on the tachometer than advertised,and offered to buy back any R6 if the customer was unhappy.
