try 16,500. That’s the redline for the Yamaha R6 :)
Didn't that get debunked, and Yamaha had to admit that their tachometers were more than a bit "optimistic?"
Oops. I just checked here and found you're pretty much right. Yamaha had advertised a redline of 17,500, while it was approximately (according to this story) 16,000, which is still quite stunning. BTW, Yamaha offered to buy back any R6 for people who were unhappy with a redline of only 16,000 RPM!
