Tubular registration label holder.
Curl up your rego label and place it inside this tube, and then attach the tube to your bike. Then remove the ugly large plastic rego label holder.
Makes the rear end or side view of your bike look much cleaner.
Completely waterproof. Authorities can turn/twist the tubular section to view the entirety of your registration label, to ensure that it complies with registration laws.
The tube is made from a flixble PVC section. It is not a hard plastic tube that may turn brittle with age.
