I went to the local keirin track two weekends back and while I was there took some pics. The quality may not be the best because I only use my phone's camera, but you may get some enjoyment from them:

nice stuff :)

Great shots! What I don't get is the glitter, sparkle, "My Little Pony" paint jobs on the Keirin bikes. Looks like they're being ridden by a 9 yr. old girl.
