yeah, like Pete Roper I don't go for anthropomorphising bikes so much (though with some Triumphs I have resorted to painting a cross on the steering stem to exorcise whatever demons remain from previous owners' behaviour, and perhaps admittedly trumping my mediocre mechanical skills).
However, I read Manzoni's GRiSO as 'Thug', and call mine from time to time 'The Beast' or 'The Thug'. She does everything pretty much sublimely, but with some quirkiness.
She just sits in the shed and glowers at her odd English stablemates. But when you want the business done, it's 'Fire up The Beast!'
