I don't but my grandson does. My yellow/black Moto is "Bumble Bee" from Transformers. He also named my pearlescent white Lambo Tandem "Jazz" from Transformers thinking it looked silver. He also named several other bikes, but I don't ride them much so I can't remember the names.

I tend to refer to them by contractions of their brand - ie: Moto, Lambo, etc.
