This pursuit frame was used at the 1990 UCI world championships for track racing on the Green Dome track in Maebashi, Japan. This is one of the two tracks in Japan where Keirin races are held.
It took Frank a whole year to get all the correct parts together to build this bike. He bought the frame in the USA but has no clue how it could have ended up there. Remarkable though is that a similar frame from the same year is in the USA too, while according to Wim van der Kaaij (RIH) only fifteen of these were made.
