Longest Winning Streaks?

The result was overturned the next day but the rest of the world didn't catch up on this for years. Technically he was undefeated for sure.

Chavez was my favourite fighter of the mid/late 80s/early 90s, but as I had an old Ring record book, I never considered him undefeated.

 

When Chavez won the title he was something like 41-0. So he still won three championships & won over 40+ bouts against world class competition without a loss.
