This is a Vespa Rally 175 from June 1970. This model was especially made for the Swiss market only and was even given it's own chassis number (VRD1T in stead of VSD1T). The 175cc was because of fiscal laws in Switzerland cheaper to operate than a 180cc. This Vespa Rally is however the same as the Italian Rally 180. The motor is stamped VRD1M.
