The anticipated all-Thai lockout at the front grid of the Asia Production 250cc category is shaping up with Apiwat Wongthananon leading the charge. The trio from Yamaha Thailand Racing dominated the first day of practice with the top three best times in the class.
Apiwat was clearly in a league of his own as the only rider to lap below the 1’56s mark. The Thai rider set the bar high for the rest of the field when he logged a blistering 1’55.089s. Anupab Sarmoon and Peerapong Loiboonpeng were second and third fastest with times of 1’56.381s and 1’56.734s.
Another set of team mates rounded up the top five – TRICKSTAR Racing’s Ayumu Tanaka and defending champion Takehiro Yamamoto posted 1’56.805s and 1’56.950s to stand fourth and fifth fastest in the day’s efforts.
