The maximum weight for this division is 160 pounds (72.6 kg or 11 stone 6 lbs),one of the traditional eight divisions.
The middleweight division can be traced back to at least 1853, and by 1873 it probably covered all weights between 140 and 166 pounds. The weight limit was first recognized by the Amateur Boxing Association of England Ltd (ABA) in 1889 as 11 stone 4 pounds and customized by Londons National Sporting Club (NSC) as 11 stone 6 pounds or 160 pounds in 1909.
