Keirin (競輪 / ケイリン, [keːɾiɴ]) – literally “racing cycle” – is a form of motor-paced cycle racing in which track cyclists sprint for victory following a speed-controlled start behind a motorized or non-motorized pacer. It was developed in Japan around 1948 for gambling purposes and became an official event at the 2000 Olympics in Sydney, Australia.

Riders use brakeless fixed-gear bicycles. Races are typically 1.5 kilometres (0.93 mi) long: 6 laps on a 250 m (270 yd) track, 4 laps on a 333 m (364 yd) track, or 4 laps on a 400 m (440 yd) track. Lots are drawn to determine starting positions for the sprint riders behind the pacer, which is usually a motorcycle, but can be a derny, electric bicycle or tandem bicycle. Riders must remain behind the pacer for 3 laps on a 250 m (270 yd) track. The pacer starts at 30 km/h (19 mph), gradually increasing to 50 km/h (31 mph) by its final circuit. The pacer leaves the track 750 m (820 yd) before the end of the race (3 laps on a 250 m (270 yd) track). The winner’s finishing speed can exceed 70 km/h (43 mph).

Competition keirin races are conducted over several rounds with one final. Some eliminated cyclists can try again in the repechages.

Keirin races in Japan begin with the cyclists parading to the starting blocks, bowing as they enter the track and again as they position their bikes for the start of the race. Every participant is assigned a number and a colour for identification and betting purposes.

At the sound of the gun, the cyclists leave their starting blocks and settle into a position behind the pacer, who is another keirin bicyclist wearing purple with orange stripes. Cyclists initially settle into different groups, referred to as “lines”, where they try to work together with others to maximize their chance of winning.

As the pace quickens, the pacer will usually depart the track with between one and two laps remaining, though the actual location where the pacer leaves varies with every race. With 1+1⁄2 laps remaining, officials begin sounding a bell or gong, increasing in frequency until the bicyclists come around to begin the final lap.

Keirin ovals are divided into specific areas: The two straightaways (homestretch and backstretch), the four turns (corners), and two locations called the “centre”, referring to the area between corners 1 and 2 (1 centre) and corners 3 and 4 (2 centre).

The race is monitored by referees. Two of the referees are stationed in towers along the backstretch (2nd and 3rd corners), while others review the homestretch area from a control room using closed-circuit cameras. Once the race has finished, a referee can signal a possible rule violation by illuminating a red light at the corner nearest to where the infraction may have occurred, or by waving a red flag. Judges then examine the video of the race and decide if a competitor committed a rules violation and should be disqualified. Once the order of finish is finalised, the race is declared official and the winning bets are paid.

競輪は自転車競技法に基づいて運営されており、主催者は地方自治体である。監督官庁は経済産業省(製造産業局車両室)で、運営統括は公益財団法人JKA。運営を補佐する団体として全国競輪施行者協議会 (全輪協)、日本競輪選手会がある。


競輪選手の登録・あっせん、育成については中央団体である公益財団法人JKAが行ない、2014年4月からは審判および番組編成・選手管理・検車の4つの業務もJKAが管掌している(経済産業省はJKAを通して競輪選手、競技会、施行者などの監督指導を行う) 。
