The loose end of almost all tiedown straps is sewn in a loop. I think that loop is to keep the strap material from unraveling and to allow a better hand-hold when you pull the tiedown tight. But another rider once told me that the loop is to slide off the main run of the strap. I don't believe that, but I use it. Simply run the bottom hook of the strap through the loop before you attach it to the hauling vehicle and the motorcycle. The loose end is no longer loose. You can still grasp it easily, but the end is captive now, and it will flap less in the wind.
