With the 19" front wheel and OEM tire my speedo reading was within 1 mph of GPS @ 70 or so. The 18" front tire gave me at least a 10% error. I would not trust the tach to be accurate enough to translate that into mph speed. The factory does test each machine on a dyno. As I recall, the machines that do not reach 84mph are sent back for re-work. Remember, that 84 mph is on the dyno...no air drag, no wind, no hills. I think it's safe to say that the stock bike with an average rider will top out around 75 mph. Of course YMMV.
