Well, I would say not exclusively Parisians. In the 70's, in France, being a biker meant to belong to a very special fraternity. What is depicted in the Joe Bar Team cartoons was based on real events, of course amplified to make it like look like a meme.
It was called the "biker' spirit". During these golden days, each passing biker would salute you. If you would break down, the first passing biker would stop to help you. This was completely out of this world.
I went to rallies and races all over Europe. The 2 stroke versus 4 stroke was real, and the two cylinders versus four too. I have ridden on most of the bikes shown on the first Album of the Joe Bar Team.
I read the book from Anne France d'Hauteville: Une demoiselle sur une moto. She did the Orion raid Paris to Isfaban Iran) on a Moto Guzzi California. I don't think the book was ever translated into English. However, I can tell you that the Guzzi she rode went all the way from Paris to Pakistan and back. Her major mechanical problem was to replace the axle on the front wheel. She dropped the bike so many times, but a Guzzi is so reliable...
Can you imagine doing Europe to Iran nowadays? this was possible in the 70's...
