Welcome Vagabondess! There are quite a few Ninjetter long distance riders here as NevadaWolf ( IB queen
) has pointed out.
I've done 4 multi-day rides: SF,CA to Ohio and Kentucky, Missouri to Ohio, SF CA to Las Vegas , and SF CA to Utah. I have a friend who has ridden his Ninjette streamliner coast to coast every summer for the past 3 years.
