I named her Kali. No one in my family rides, so everyone was a bit freaked out when I showed up with what my aunt referred to as, "an engine with wheels on it". I figured I'd just swim with the current. Kali is the Hindu goddess of violent death, patron of assassins.
My first thought was to name the bike Yama, the Hindu god of (natural) death and machines. But that's probably where "Yamaha" comes from. I couldn't very well use the name for a Honda.
