World Flyweight Championship

Undaunted by the Chang loss, he won two more fights and a little over six months later shocked WBC and Lineal Flyweight Champion Gabriel Bernal, winning the world championships in his home country at Indoor Stadium Huamark, Bangkok.^[1]

Chitalada is perhaps best-remembered for his fights with Bernal. The two met again twice in Bangkok. On 22 June 1985, Bernal fought Chitalada to a twelve-round draw, Chitalada keeping the titles. Bernal made another attempt eighteen months later, but on 10 December 1986 he lost another twelve-round decision to Chitalada. This was Bernal's final attempt at the Flyweight titles.

Chitalada brought stability to the WBC and Lineal Flyweight titles, the six title holders prior to Bernal all losing the belts in their first defences, and Bernal losing his second defence. Following the first Bernal fight, Chitalada made six title defences (and won several non-title fights). During this run he defeated former world champions Charlie Magri^[2] and Freddy Castillo. He lost the titles on 24 July 1988, travelling to South Korea and losing a twelve-round decision to unbeaten (at that time) Yong-Kang Kim.

After winning three more fights, Chitalada lured Kim for a rematch in his home country of Thailand. This time, it was Chitalada who came out on top, winning a twelve-round decision. Chitalada made four more title defences after he regained the titles. In his third defence, he made his second fight in the Western Hemisphere, defeating Richard Clarke by an eleventh-round knockout in Kingston, Jamaica, thus retaining his titles. For his fourth defence, he travelled to Seoul to avenge the only other loss in his career, to Jung-Koo Chang. Following the Chang fight, on 15 February 1991 Chitalada defended his titles against fellow-countryman Muangchai Kittikasem. This fight ended Chitalada's reign as he suffered his first knockout, Kittikasem stopping him in Round 6 to take the titles. Chitalada won two more fights before challenging Kittikasem to a rematch, but the result was the same, this time it ended in a ninth-round stoppage. That fight would be the last of Chitalada's career, he retired and never attempted a comeback.
