Milano Taranto, twice as detailed in Benzina #1, where you can see this photo in glorious high resolution. I was lucky enough to see a real Bicilindrica paraded by Sammy Miller at his Italian day, and he thinks the bike was Fabio Taglioni's inspiration for the bevel twins. And why not? Taglioni admitted being influenced by Guzzi's horizontal racing singles when he created the 750SS, admiring the way the design ensured plenty of cooling air and a low centre of gravity. Carlo Guzzi created the Bicilindrica by doubling up two 250 singles, and maybe if Taglioni had admitted to admiring the Bicilindrica rather than Guzzi's singles (when his 750 bevel was effectively two 350 singles) he might have been accused of plagiarism rather than genius.
