I like the answers by Ponch and Romans.
That being said, IMHO, to me a soul refers to a living breathing person or animal. I know we have souls, not sure about the critters. Just like a bike does not have a heart in the traditional or physical sense. Bikes of course have oil pumps and oil is the life blood of the bike. So there is yet another contradiction to consider or muddy the water so to speak.
What I consider to be the heart or maybe the soul of my bike is also partially the feeling I get each time I ride knowing my bike will get me from point a to point B reliably and safely. I also am comfortable jumping on my bike and just hitting the highway as long as I keep an eye on the gas. Day or night alone or with others, I have no concerns about my bike mechanically. Yes things happen on the road, but sometimes it is our fault and sometimes not. My bike is not blazing fast, but I feel it has enough torque and power to tow another bike if one breaks down on the highway, rather than ride 30 miles or so to town call someone and ride back. I carry extra gear to make sure we all get to town and can wait at a safer place.
Sometimes I feel others come up with a new buzz word or phrase trying to signify they and their bike are better than mine or others. That to me is an insecurity issue for them, not me. We all ride for the freedom and the enjoyment, period. Lastly, regardless of the "badge" or brand if I encounter a bike on the side of the road I will stop to check on folks and offer whatever meager assistance I may be able to provide, be it gas or a jump or a phone or even a slow ride (tow) to the next town. I do not feel I am better than anyone else. I am merely me wishing we could all get along and enjoy our time on 2 wheels.
