Don't wait to do it. You may never get the chance again.
I wish I would have done a better job tracking my routes through the lower 48 and Canada. I didn't do much interstate on my rides. I prefer state highways and country roads because I try to avoid major cities as much as possible. My first trip on the quest to ride all 48 states was on my '11 Versys 650 in 2012. I completed my goal in 2016 riding different motorcycles. In all I rode a 2010 Vulcan Voyager, 2011 Versys 650, 2012 Concours 1400, 2014 Triumph Trophy SE, 2015 Yamaha FZ07, and a 2016 Harley Road Glide Ultra. Total miles I put on those bikes was 150,000 miles.
Then I blew out my back, had surgery, got infected, and my long touring rides are behind me. I now trailer or haul bikes to where the good roads are and enjoy day rides with a lot of breaks.
