So i was riding today, and going 55 passing cars, i have no idea why people were driving slow, well when we stopped i asked my buddy if i was going too fast for him cause he is nervous riding cause he too just started, well his reply was, dude you werent going 55 you were actually going 80. ok... something is wrong with this picture..... ANY way to fix my reading of my speed? nothing is modified on the tires or speedometer, could it just be a bad gauge?
