===Betting===
Bets that can be made on Keirin races include, but are not limited to:
* {{nihongo|'''Exacta'''|2車単|nishatan}} – selecting the first two finishers in exact order
* {{nihongo|'''Quinella'''|2車複|nishafuku}} – first two finishers in any order
* {{nihongo|'''Trifecta'''|3連単|sanrentan}} – first three finishers in exact order
* {{nihongo|'''Trio'''|3連複|sanrenpuku}} – first three finishers in any order
* {{nihongo|'''Quinella Place''', or '''wide'''|ワイド|waido}} - selecting two to finish in the top three, in any order.
Some wagers cannot be placed if there is a small number of competitors in the race.

During major race meets, some jackpot wagers are offered:
* '''Dokanto! 4 two'''<ref>{{cite web|url=http://keirin.jp/pc/dfw/dokanto/pc/about/dokanto4/|title=Dokanto! 4 two（ドカント フォートゥー）とは?|website=keirin.jp|access-date=28 January 2013|language=ja|url-status=dead|archive-url=https://web.archive.org/web/20130603063335/http://keirin.jp/pc/dfw/dokanto/pc/about/dokanto4/|archive-date=3 June 2013}}</ref> – selecting the exacta in four consecutive (typically the last four) races.
* '''[[Pick 6 (horse racing) |Dokanto! 7]]'''<ref>{{cite web|url=http://keirin.jp/pc/dfw/dokanto/pc/about/dokanto7/|title=Dokanto! 7 （ドカント セブン）とは?|website=keirin.jp|access-date=28 January 2013|language=ja|url-status=dead|archive-url=https://web.archive.org/web/20130211142322/http://keirin.jp/pc/dfw/dokanto/pc/about/dokanto7/|archive-date=11 February 2013}}</ref> – this is what would be called a Pick 7 in horse racing in that the bettor selects the winner of each of the last seven races of the day.

The money bet into the Dokanto wagers can carry over if there are no winning tickets, even to subsequent race meets at another velodrome in the country.

In extraordinary circumstances, races have been declared no-contests, forcing velodromes to refund millions of yen in bets. Such results are generally known as a {{nihongo|''failure''|不成立|fuseiritsu}}. A race at Shizuoka velodrome on 2 January 2008 was declared a failure when the back wheel of the pacer's bicycle nicked the bicycle of an actual competitor, causing him to fall.<ref>{{cite web|url=http://keirin.jp/pc/dfw/dataplaza/guest/raceresult?KCD=38&KBI=20080102&RNO=9|title=Race Results: Shizuoka - Race 9 - January 2, 2008|website=keirin.jp|language=ja|access-date=29 December 2008|url-status=dead|archive-url=https://archive.today/20120709104013/http://keirin.jp/pc/dfw/dataplaza/guest/raceresult?KCD=38&KBI=20080102&RNO=9|archive-date=9 July 2012}}</ref> In a race at [[Iwaki-Taira Velodrome]] on 14 December 2008, separate infractions resulted in the disqualification of the entire field; all but one of the competitors were handed a one-year suspension by the velodrome after the race.<ref>{{cite web|url=http://keirin.jp/pc/dfw/dataplaza/guest/raceresult?KCD=13&KBI=20081214&RNO=10|title=Race Results: Iwaki-Taira - Race 10 - December 14, 2008|website=keirin.jp|language=ja|access-date=29 December 2008|url-status=dead|archive-url=https://archive.today/20120714083117/http://keirin.jp/pc/dfw/dataplaza/guest/raceresult?KCD=13&KBI=20081214&RNO=10|archive-date=14 July 2012}}</ref><ref>{{cite web|url=http://www.zakzak.co.jp/top/200812/t2008121505_all.html|script-title=ja:いわき平競輪で9人全員失格... 前代未聞の珍事ナゼ？|website=zakzak.co.jp|language=ja|access-date=29 December 2008|url-status=dead|archive-url=https://web.archive.org/web/20090201030101/http://www.zakzak.co.jp/top/200812/t2008121505_all.html|archive-date=1 February 2009}}</ref> The suspensions were lifted four months later.
