One of the most unusual brand associations in the motorcycling industry is that of Bimota and Borsalino. Every now and then, the boutique motorcycle maker hooks up with the Milan-based hatmaker, founded in 1857, to create a limited edition motorcycle. (The European equivalent of a Neiman Marcus model, if you like.) The machine above is a Ducati 1078-engined DB6 Delirio in a rather unflattering lawnmower-inspired livery, with Borsalino branding. The DB5 Borsalino is a more successful, with a low-key anthracite paintjob. We’d still rather have the delicious 1976 HDB1 racer though: engineering always triumphs over marketing.
