A numbered limited edition built on the GTS 300 to honour the 1951 Vespa Sport Sei Giorni, which won gold medals in the Varese International Six Days trial. It has retro touches: a low-mounted headlight, exposed metal handlebar, black number plate with white lettering, red accents and a serial-numbered Special Edition plate. Standard ABS, LED daytime running lights and a USB port keep it modern.
