> It was explained to me like this; > There are stiff federal fines if an imported motorcycle has a speedo that shows SLOWER than actually moving. Therefore, Honda (and presumably others) intentionally error on the safe side with about a 5% ‘above actual speed’ reading. The error increases as speed increases though so the Honda speedos can be 10% too high when approaching triple figures on the speedo. > Real or myth, I don’t know. Twas what I’ve heard and been told without any verification, but it makes sense… I guess. I ALSO LIKE THE “idiots who buy motorcycles like to think they are going faster than they truly are theory” some bikes read the speed off of the front wheel, meaning if your doing a wheelie for a long enough time it would appear that the bike was going zero mph. ---
