Most of my cars have had names. The Jeep is COMRADE JEEP! (subnames: The Red Menace, The Jeep of the People)
My explorer was named Gypsy (She was also flamboyantly red, and liked to wander)
My old 74 Buick Regal was the Sherman. (Dark green, and was tanklike)
Etc etc etc.
I dont know if I could name a bike though. I'm the one powering a bike. It is a mere extension of me. A car though... that's got an engine, a mechanical soul.
