Male and female riders name their bikes with both male and female names.
However, the dominant gender of motorcycles seems to be female.
There are several theories on why this happens.
It could go back to the convention of sailors to refer to their ships as female and bestow female names. In ancient times they were named after goddesses who would protect them on their voyages. Most boats, trains and other vehicles are still given female names today.
Another theory suggests that it stems from languages such as French and German that give nouns gender. For example, “the motorcycle” is “la moto” in French and “la motocicleta” in Spanish where “la” bestows the feminine gender.
However, in Russian motorcycle (mototski) is masculine.
Another linguistic theory revolves around slang terms such as “she’s a beauty”, “she’s hot”, or “she really goes”.
If it’s a problematic bike it’s a “bitch” or a “whore”.
