My speedo cable fell out of the back of the speedo (behind the back of the headlight) at about 500 miles. I was about 20 miles from home so I zip-tied the cable to the crash bar (everyone should always carry zip-ties, they make you smarter) and screwed it back in when I got home, easy fix. After reading this, I will be checking the lube at the hub end because I've noticed about a 5mph needle shake sometimes at 60mph+.
