That Japanese track racing story vid ?

You know the one ? it was linked somewhere, I have searched google, youtube and various forums, don’t where I got the link from…

It was like 5-10 minutes long, had a tour of a Keirin facility, the betting setup, frame manufacturers, training, practice and racing.
One scene I remember about 50 bikes lined up hanging off a wall at the clubhouse.

Would like to see it again :?
