Drakie made some comments about no MX bikes when the Vinduro scene was being set up in Vic. . I don't think he intended to ban all MX bikes, as even many early European stuff is based on MX bikes.
I think he was worried about a lot of MX bikes just turning up for the ride & overshadowing the Enduro bikes, but it seems their are a few that are hanging onto his every word as if it was gospel.
MX bikes were converted in the day & should be allowed to now.
"Spirit of the Era" is an old line that springs to mind, even though their are many different interprtations of it.
As for mufflers, EVERY BIKE NEEDS TO BE MUFFLED PROPERLY
Just because it's a Enduro or Trail bike muffler doesn't mean it's effective.
Some of the Venues we have are near houses, we need to fly under the radar if we are to keep these venues.
