They do so because Keirin is a gambling sport in Japan like horse racing is in the US.
When those same racers compete in other races, international races they don't use the Keirin style bikes.
Yeah, that's why I said if I were to buy a Keirin bike, I would be riding it on the street, not the track. And also Keirin bikes only have to be NJS certified for Keirin races in Japan. Internationally NJS doesn't even regulate the Keirin bikes.
