I know, but as I said a lot of enduros are run by riders without plates because they can't/won't get their bikes plated. This is part of a larger problem facing offroad riders as areas available continue to shrink and be closed off or cut into pieces forcing riders onto public roads. The temptation of a long ride linking many areas together is enough to draw a lot of MX and dirt bikes. These events also help local communities with people who camp, rent out rooms, and eat at the local dinners. It seemes like harrasment for the police to wait for them at the end of their ride. On the flip side Zach is correct. All AMA santioned events require bikes to meet guidlines for noise, spark arresting, and be street legal if traveling on public roads. However, all you need to do is drive around a town like McArthur to see the ATVs that are never street legal being used by locals on the road. Are the police stopping and ticketing them too? I don't know. But if they are it certainly isn't effecting the use of ATVs on public roads.
