On late-fall Blue Ridge Parkway tour I saw lots of moto tourers but zero bicycle tourers. Moto folks were always polite, sometimes even waving "hi". A lot of 'em have panniers & rack case so it's hard to tell if they're day-tripping or credit-card touring or camping. Often when I'm struggling up local hills & see a moto pass I wish I had some of that horsepower.
Sweet setup here, camp trailer & sidecar to give rides to wayward females LOL:
BTW in reading about GPS device turn-by-turn routing problems I discovered that motorcycle tourists have same problems as bicycle tourists, ie moto tourists often want selected scenic routes not the fastest/most direct.
