Why not? Many European brands supplied their bikes with Japanese parts when they became available in the seventies. If only because at the time Campagnolo was expensive, arrogant and parts availability was lousy. And not just on the cheaper models either. Flandria raced with Dura-Ace on their pro bikes, as did Koga. Gazelle had a SunTour Superbe-equipped model in the Champion Mondial line-up and put Vx on all of their their hand-built touring versions.
