On my GS1000 I had a car type holder on the inside of the fairing. One day it blew away while I was storming down the hill at well over 100 mph late as usual. Because there was only a few days to go until it expired, I didn't worry about it.
A few days later, doing well over 100 again, I got pulled over. Because there was no tax disc the cops done me for that and not the speeding.
After a visit to the LVLO, I could confirm that I had taxed the bike and got away with it.
