Bantamweight is a weight class in combat sports and weightlifting. For boxing, the range is above 115 lb (52.2 kg) and up to 118 lb (53.5 kg). In kickboxing, a bantamweight fighter generally weighs between 53 and 55 kilograms (117 and 121 lb). In MMA, bantamweight is 126–135 lb (57.2–61.2 kg).
The first title fight with gloves was between Chappie Moran and Ray Lewis in 1889. At that time, the limit for this weight class was 110 pounds. In 1910, however, the British settled on a limit of 118.[2]
From 2018 to 2019, a 8 men tournament called World Boxing Super Series was held to find the best bantamweight in the world. The tournament was won by Naoya Inoue, who defeated Nonito Donaire in the final.
On December 13, 2022, Naoya Inoue became the first undisputed champion of the division in the four-belt era.
