people have gone from india to England on 50c scooters. Read of 2 people taking a c3 cube 50 cc scooter from Vancouver to out east 5000 k . On steep hills they did 7 K per hour but those hill are long and go on and off for 50 Miles.
The first motorcycle trip accross the usa was 1903 on a 3.5 horse power motorcycle. It all depends on do you got the time to go slowly to where you want .
Life's journey is not to arrive at the grave safely in a well preserved body,but rather to skid in sideways totally worn out shouting WHAT A RUSH, WHAT A RIDE.
