Washington state: a street plated dual-sport motorcycle is good in most places on or off-road, including roads and trails in national forests and federal lands, with just a street plate. Our OHV "sticker" is traditionally for a non-plated dirt bike. We don't sell a non-resident OHV "sticker". The only places that you would need to supplement your street plate are state owned DNR lands and ORV Parks. This supplementation can be accomplished by purchasing a Washington State Discover Pass (https://discoverpass.wa.gov) for $11.50/day or $35/year, resident or not.
I understand Oregon and Utah to be the same way, correct me if I am mistaken,. On our TW Father's Day gathering in Oregon last year, we needed to get Oregon's 2-year OHV sticker because we were riding inside of a state OHV area. In Utah, again, on our gatherings we've never needed a OHV sticker because almost all of our riding has been done on federal land. If you go to a state OHV area, then yes, you will need their sticker. Idaho seems to simply require the OHV sticker for riding trails on any public lands. For $12.50/year, I'm okay with that.
