I don't follow it closely but there have been several stone cold stock bikes that have been capable of over 180 in the past 8-10 years. Yamaha had one 7 or 8 years ago that they advertised would go from 0 to 170 to 0 in less than a mile. STOCK out of the factory. These things are hot. A friend of mine sold his 600 cc crotch rocket because he found himself regularly exceeding 100 mph between stoplights. He came in one day and said he was going to sell it because he got in the air over and overpass. He didn't want to die. They are faster than anything you can imagine.
