Japanese Vivalo Keirin Track Racer.
Keirin racing is big in Japan and the bicycles are some of the best in the world. There are strict equipment regulations and every part has to have an NJS stamp. For some conponents there are only one or two manufacturers worldwide who are awarded the NJS standard.
Sturdy track dropouts. The whole frame is chromed under the paint. Some Keirin builders even design their own specialist steels. Note the NJS stamp on the chain. It's still in the condition I got it but I'm going to add some bling. White ostrich leather Keirin saddle is already waiting.
The forks are tight! Pure racer. Regulation states no brakes. If none of them have brakes then they can't suddenly slow down and cause a pile up in the velodrome.
