Motorcycling is mainly about the bikes. To some of us it's about creating something and to others it is ALL about riding. It's nice to find like minded souls to talk and hang with but I find the "culture" to be a bit of a myth. It's all a bit reality TV if you will.
Example: I race bikes and love to talk to people about their race bikes and what has been done to them, but I'm all about the modifications and technology and problem solving and many racers are not. I also find that once we get past the bikes, there is nothing I have in common with them and run out of things in common to chat about, so the conversations tend to be about the bikes and it's never about how cool it is to be a racer or any such BS.
Many decades ago when I rode a bike, I found that other riders had things in common that we could talk about - weather, shitty cage drivers, the weather, rotten roads, the weather, great places to ride and so on, but outside of riding and the shared experiences there really was no "bike culture". It was always affirming to know that you were not the only person on the planet not smart enough to get a car, but at least where I lived we didn't hang out at the local cafe soaking in the "culture" let alone being one with nature or the machine or any of the BS I read about today.
Sure it was nice sometimes to ride with others but most of the time they were either too slow or too fast or wanted to go somewhere I had no interest in going.
Motorcycling is something you do for yourself because you enjoy something about the tactile response or the feeling of just being out there doing your own thing. It's a solitary activity that if we are lucky we get to do with friends and strangers (new friends) from time to time.
Get the bike running safely and reliably and learn to ride safe and have fun with it. You will experience the bad and the good and I think you will get a lot out of riding from fun and exhilaration to an awareness of your own vulnerability.
Enjoy it for wat it is and feel free to ignore anyone else's idea of what it's all about - including mine
