These events are usually organized to the point that all or most of the local law enforcement knows the dual sport will be going on. Therefore they kind of look the other way mostly. State Troopers can always be a problem. You need to have a plate, ON YOUR BIKE, not tie-wrapped to your chest protector. Now if that plate is legal, or from your Harley, or whatever, that's a different story. I'm not telling you to break the law but if you ride calmly on the roads, with respect, not speeding, wheelieing, spraying your buddies with stones, flat tracking the corners, etc. then you 99.9% of the time will have no problems with the law. If you break road laws on a dirtbike with a questionable plate, well then you could end up with, fictitious plate, no signals, no horn, no mirror, no no no charges. I've never seen that happen but it can if you go crazy on the road sections. I did get stopped one time on this ride in the small town we blow through. The local cop just looked to see IF I had a plate, and sent me on the way. So likely most plates are NOT legal but they have the appearance to be legal. These events usually raise money for the locality it is held in, so the cops want to not scare people away from future events. Except Troopers, they usually are by the book all the time. Can't help you there, just ride calmly, wave and don't attract attention and you'll be fine. And don't tie wrap your plate to anything, put it on the fender. That's a sure red flag, that I've seen several times ending in tickets. For some reason the cops don't like that, go figure!
