MotownMadman Unfortunately the 17500 redline claim wasnt true.Here are the details.
Redline lies: When Yamaha introduced its 600cc YZF-R6 motorcycle, the 17,500-rpm redline prompted more than one comparison to Formula 1 engine speeds. When the bike was run on various aftermarket dynamometers, it turned out the tachometer read nine percent fast, and the engine turned out to be limited to a true 16,000 rpm. However, at the rev limiter, the bike’s tachometer reads 17,500 rpm. After this news, Yamaha offered to buy back any of the early R6 units sold, no questions asked. It’s strange that Yamaha allowed the tach to enter production; the R6 is a superb machine that is closer to being a dedicated track bike than ever before.
