I toured Europe the UK and Ireland on my own for six months on a K100 BMW, I had a blast, so many great places, my favourite countries where Ireland, Scotland, Italy and Greece, even took the bike onto the Greek island of Paros, that was brilliant.
I'd love to do Canada or north east US, I reckon Vietnam could be fun also, it might be better if you purchase the bike when you get there, much cheaper that way, also I never had any issues riding in left hand drive countries, a good tip is to ride near the centre of the lanes on two land roads and leave a reminder note on some tape near the ignition key, a girl I met in Austria had some masking tape on hear fairing, it said in capitals "ride on the right"
Have fun, it's a great experience.
Sorry about the pic being backwards, it's the French Alps, heading through Alps Maritimes.
