Round 4 of the Asia Road Racing Championship closed with a dramatic, almost surreal Supersport 600 Race 2.

The race ran in two parts. In front of a packed grandstand, MUSASHI Boon Siew Honda’s Zaqwan Zaidi made up for a lackluster performance on Saturday, by getting away first and opening a gap on the rest of the field, which was led by Rama Honda’s Taiga Hada, who was hounded and then overtaken by Chalermpol Polamai, who opened up a few bike lengths on the rest of the field.

Then everything changed.

First the 22 year-old Malaysian crashed out of the lead at Turn 10 at the start of lap 3, then his team mate, Teppei Nagoe went down a few seconds later. With Zaqwan unable to get to safety, the red flag was shown and the riders returned to the pits.

As the last bike came in a heavy rain storm started, causing a delay to the restart as tyres were changed and a wet race declared over nine laps.

With the rain almost stopped, but with standing water on the track, Chalermpol took the early lead from Decha Kraisart and Ahmad Yuhistira on the Manual tech KYT Kawasaki. Decha quickly got past his Yamaha Thailand team mate, followed by Yudhistira, who pushed Decha hard for another lap. Unable to find a way past and with Decha making the wet conditions his own, a few bike lengths soon appeared between him and the Malaysian. Behind Yudhistira, a similar gap opened up to Chalermpol, and then there was another two seconds back to Yuki Ito, Dimas Ekky Pratama, Kasma Daniel Kasmayudin and Anthony West, who were fighting for fourth.

Decha remained poised at the front, to cross the finish line 1.6 seconds in front of Yudhistira and Chalermpol, who was 5.7 seconds clear of the four-way battle for fourth, which was won by Dimas from Kasma, West and Ito. Ratthapong Wilairot had another good outing to finish eighth ahead of Azlan Shah and his AP Honda team mate, Tetsuya Yamaguchi.
