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.
