Random thought of the day: Why do most motorcycles have their drivelines on the left hand side?
While over the years motorcycles have had drive lines on either side of the vehicle as you sit on them but by a vast majority for most motorcycles the driveline seems to be on the left hand side.
Is there a technical, social, political or any other reason for this?
Harley seems to make it’s big block models with a left side driveline, but the Sportsters are on the right. For most KTM’s the chain is on the left but with the 640 LC4 models the chain was on the right, BMW has made the R1200GS with the driveshaft on both sides in different iterations of the model. I can’t recall ever seeing a japanese manufactured bike with the driveline on the right side.
