Police were called to the scene on Ban Thai Nam-Saphan Bueng Chawak Road in Moo 8, Doem Bang Nang Buat district, at 12.30am.
Residents said a group of boys often raced their bikes on the road late at night, pairing off and driving towards and past each other at top speed.
Police had already been summoned to the location Tuesday evening, but the racers fled, only to regroup later.
The deaths occurred when one racer lost control and crashed head-on into the other.
The other youths then fled the scene.
