Dave Barr, did that trip on an old 4 speed shovel wide glide about thirty years back & had no legs and was just a stock old shovel, then road it around the world.well done mate! I would not do it myself.
thats him was in US military walked on a land mine ( long story) but road that shovel around the world on his own, some places had to look down & lout or could get robbed also had to run the motor on 90W gear box oil in some third world countries as all there was & the old motor kept going . every time he dropped the bike he broke his artificial legs had to repair on his own.
