Minimumweight

Limit: 105 lb / 47.6 kg

The smallest professional weight class. Recognised by the WBC and WBO from 1987 and the WBA / IBF shortly thereafter, the 105-pound limit is fought almost exclusively by Latin American and East-Asian fighters. The most decorated minimumweight in history is Mexico's Ricardo López, who retired in 2002 with a 51-0-1 record and the only undefeated reign of more than ten years in modern boxing.

Trivia

  • Ricardo López's 22 successful minimumweight title defences is the divisional record.
  • The Thai fighter Wanheng Menayothin matched Rocky Marciano's mythologised 49-0 record at minimumweight before losing in 2020.
  • The IBF still calls the class 'Mini Flyweight' on its sanctioning forms; the WBC's 'Strawweight' is the broadcast standard in the United States.
