You can find turbos and superchargers for most of the Japanese bikes these days but I haven’t seen much for Italian bikes. Koehler, a German company, makes this Moto Guzzi supercharger and it looks really nice. Of course, the Guzzi V-twin is mounted transverse in the frame so a blower just fits in so neatly. Sometimes, when an engineering project looks right there’s a good chance it works pretty well, too. This blower look right.
