BKFC Weight Classes Guide
All 10 men's + 4 women's divisions, plus what each weight class means for betting outcomes.
Men's divisions
BKFC contests ten men's weight classes, mirroring modern boxing with one key addition: Cruiserweight (205 lb) sits between Light Heavyweight and Heavyweight. This is the division that typically houses former UFC light-heavies and small heavyweights — some of BKFC's most recognizable names fight here.
| Division | Limit | Finish rate |
|---|---|---|
| Flyweight | 125 lb / 56.7 kg | ~65% |
| Bantamweight | 135 lb / 61.2 kg | ~60% |
| Featherweight | 145 lb / 65.8 kg | ~65% |
| Lightweight | 155 lb / 70 kg | ~70% |
| Welterweight | 165 lb / 75 kg | ~72% |
| Middleweight | 175 lb / 79 kg | ~75% |
| Light Heavyweight | 185 lb / 84 kg | ~80% |
| Cruiserweight | 205 lb / 93 kg | ~82% |
| Heavyweight | 265 lb / 120 kg | ~85% |
Finish rates are approximate based on historical BKFC results. They're inputs into our model's weight-class baseline.
Women's divisions
Four women's divisions: Strawweight (115 lb), Flyweight (125 lb), Bantamweight (135 lb), Featherweight (145 lb). Historically Strawweight and Flyweight have been the most active, with Bantamweight growing as more roster depth develops.
Women's fights have roughly the same finish rate as men's at the same weight — but tend toward more decisions than KOs, and fewer doctor stoppages per bout.
Why division matters for betting
Three effects compound across weight classes:
- Finish rate rises with weight. Bigger punchers, smaller margin for error. At Heavyweight, 85% of fights end inside the distance. This pushes "fight goes distance: NO" into +EV territory on many heavyweight cards.
- Cut frequency rises with weight. Heavier gloves — I mean knuckles — open up skin faster. Doctor stoppages are twice as common at Heavyweight as at Bantamweight.
- Style matchups reshape by division. Pressure fighting dominates at Heavyweight (nowhere to hide in 2-minute rounds with 240 lb guys punching). Technical boxing (jab, footwork) plays better at Bantamweight through Lightweight.
Catchweights
BKFC occasionally sanctions catchweight bouts — a weight negotiated between the two fighters outside the standard classes. Read the contracted weight carefully: a fighter who normally campaigns at 175 lb facing someone who normally fights at 185 at a 180-lb catchweight is often giving up power but gaining speed.
Our model tracks a fighter's standard division separately from the contracted bout weight. When they differ materially (e.g. 10+ lb), it's a signal worth noting.
