Profile

Superlek Kiatmuu9 is controlled violence.

He does not rely on chaos, intimidation, or wild exchanges. He dismantles opponents through precision, tempo, and sustained damage. His nickname, The Kicking Machine, is literal — few fighters in the modern era have applied low kicks, body kicks, and knees with such speed, accuracy, and consistency across divisions.

He rose rapidly through Thailand’s stadium system, collecting national and Lumpinee titles before his twenties, then carried the same technical clarity into the global ONE Championship era without altering his core style.

Fighting Style

Superlek is a textbook Muay Femur, optimized for modern scoring and small gloves.

Key traits:

  • Extremely fast and accurate kicking volume

  • Heavy emphasis on low kicks and body kicks

  • Sharp elbows in transitions

  • Efficient clinch knees without stalling

  • Strong balance, recovery, and ring awareness

He wins through accumulation. Opponents typically fade from sustained damage to legs, body, and posture rather than isolated moments.
