Why do you OP think there's an "explosion" in ridership? Do you have some official numbers to prove it (new Mx licences issued through ministry ...), or you by eyeballing it on the street. I don't think there's many new people getting into it.
There was a recent post where someone linked to stats on bike registrations for the last decade or so. The number of bikes on the road is definitely increasing, however, the stats aren't detailed enough to say how many are new riders. It's reasonable IMO to assume that many of these new registrations are new riders.
