270 kmph is 169mph. If actual speed is only 149mph like most people, that represents nearly a 9% error, much much much higher than other people have seen. Also, 170mph represents a very close approximation of the top end allowable by the rpm red line and 6th gear ratio. When you factor in wind resistance, it sounds perfectly plausible that an unlimited 1er could close in on 170mph.
