It was the fifth K-1 World MAX final for middleweight kickboxers (70 kg/154 lb weight class), involving eight finalists and two reserve fighters, with all bouts fought under K-1 rules.

Seven of the finalists had won elimination fights at the K-1 World MAX 2005 World Tournament Open, while the eighth, Virgil Kalakoda, had been invited despite losing his elimination match.

Prior to the tournament both fighters had stated their intention to be the first fighter to win two K-1 MAX finals, with Buakaw becoming the first two-time champion defeating Souwer via KO in the second round of their match.

Other results saw Muay Thai world champion Yodsanklai Fairtex defeat SuperLeague starlet Kamal El Amrani and Kenpo Karate expert Fernando Calleros defeated local fighter Kozo Takeda, both by decision.
