I got them michis both on today and ill run them a little higher and see if they stay on.
If anyone wants to do the nationals and is worried about cost etc, i had sent 2 of 18 inch X11trials tyres up there for a bike we were putting together but thats not going to plan so there will be at least one spare up there if anyone whats to use it or buy it for $60, there is no excuse for not coming out and giving the round track a crank on your Motocrosser now you have access to a cheap rear tyre. ( half new price easy
