During a couple of trips to Happy Bay from SBR I was amazed at how many of those 2 wheelers were not registered so I did a survey of just those who passed me (and everyone else).
1st trip,,,18 bikes..4 with plates.
2nd trip..13 bikes..4 with plates (maybe the same 4 <img src="http://www.traveltalkonline.com/forums/images/graemlins/Wink.gif" alt="" />)
Why would they stop for police since the plate would be the only easy way to find them?
