My Speedmaster I have affectionately named the Speedmistress because it takes me away from my missus
My K100 BMW I call the Rhino after a bog job on the fairing didn't dry in time for me to get going on a long journey so I just painted over the wrinkly still wet bog and it looked like Rhino skin. Still does.
My old Honda 4 I call the Absconder (sort of rhymes with Honda)
