Pretty much ALL sportbikes have optimistic tachos. But a 9% error is much more visible on a bike with a 17,500 redline than an 11,000 redline.
Sure, it wasn't very smart to make the high redline the key point of their marketing, but it really isn't that big a deal. Manufacturers exaggerate all the time. Are you going to have your trust in Honda and Kawasaki violated when you find out that the CBR600RR doesn't REALLY make 130 hp, or that the ZX6-R doesn't REALLY weigh 362 lbs dry?
