I never owned a motorcycle but my brother's first bike was a BSA Bantam. That was back in the 1940s. His next bike was an Indian.
My first motorcycle was a Honda. I traded it for a Husqvarna and loved it. Went through many and my last one I had was a Honda XR 400.
My first one was a 250 Yamaha.
'Standard bike' from Mario Kart had been my one and only motorcycle.
I don't plan on getting one in real life
1976 Suzuki GT 380.
