Although many flaws exist within the lower weight classes regarding division naming and weight limits, the UFC Heavyweight division is, for the most part, accurate. The Ultimate Fighting Championship (UFC) and most other North American MMA organizations such as Bellator MMA, WSOF, and King of the Cage (KOTC) abide by this interpretation to their 206–265 lb athletes as heavyweights. ONE Championship’s heavyweight division is at 226-265 lb. The UFC heavyweight division is always consisting of the best heavyweight MMA fighters in the world.
