 The outfit was soon 'outlawed' by the FIM, the European road-race regulatory body, as the front and rear wheels (non-sidecar) were designed to be out-of-line, hence deemed to be a three-wheeler (or "cyclecar"), causing Vincent to revert to his 'old', conventional outfit.For the 1972 season Vincent used a Munch-URS engine based on a Helmut Fath design.He finished fourth in the Championship with a win at the Finnish Grand Prix held at Imatra.
