Victor had his first GP podium in 1973 at Hockenheim in Germany riding his 350 Yamaha to second place behind Teuvo Lansivouri. At the Italian GP at Monza that year he was involved in the tragic accident that took the lives of Jarno Saarinen and Renzo Pasolini. A fall at the Yugoslavia GP in June led to him missing the rest of the 1973 season and part of 1974. He won his home 350GP at Montjuic in 1974. In 1975 he competed in the 250 (3rd at Hockenheim and 4th at Andersdorp) and 350 championships (3rd at Brno ) on the revolutionary monocoque SMAC Yamaha of Eric Offenstad, and F750 on a TZ750 Yamaha, combining several podiums with numerous mechanical problems.
In 1976 Victor rode for the Freddy Swaep team, with uneven performances in the 250, 350 and 500 classes. He also competed in F750 championship on a TZ750 Yamaha, coming second at the controversial Jarama event. In the latter part of the season problems with the team meant he had nothing to ride for the race at Silverstone but Sonauto Yamaha gave him the injured Patrick Pons bike. Victories in the next two races at Assen and Hockenheim meant he won the Formula 750 European championship, just two points ahead of the American Gary Nixon and his Kawasaki.
