Weight Limits
In professional boxing, the division sits between two other major weight classes:
Lower Bound: Above 118 pounds (53.5 kg) – Bantamweight
Upper Bound: Up to 122 pounds (55.3 kg) – Junior Featherweight / Super Bantamweight
Next Division Up: 126 pounds (57.2 kg) – Featherweight
Governing Body Names
Different boxing organizations use different names for this specific weight class:
WBC & WBA: Super Bantamweight
IBF & WBO: Junior Featherweight
Characteristics of the Division
Fighters in this division are celebrated for balancing blistering speed with surprising punching power. Because they are slightly larger than flyweights and bantamweights, they often carry enough power to score dramatic knockouts while maintaining the rapid-fire combinations, quick footwork, and high work rates typical of the lower weight classes.
