A convincing display by Astra Honda’s Rheza Danica Ahrens and Awhin Sanjaya left the rest of the AP250 field fighting over the remaining places in Race 1. Rheza’s 15-year-old team-mate and only realistic title rival, Mario Suryo Aji, fell on lap 2, thereby handing over another 25 points advantage. Mario had earlier led a front row lockout after a perfect qualifying session for the Honda home team.

With the rest of the field unable to match the pace of the flying Honda’s at the front, a group of five riders behind them fought a pitched battle for third. Manual Tech KYT Kawasaki’s Andy Fadly initially looked strongest, before Muklada Sarapuech, riding with the left clip-on of her Honda adapted to accommodate her injured wrist, pushed her way through, hassled all the way by Rafid Topan Sucipto. M. Faerozi  threatened them just behind, while Anuparb Sarmoon fought to stay in contact.

Rafid forced his way past Muklada on the final lap and held his advantage to grab the final place on the podium, while she, in turn, got to the finish line 14 hundredths ahead of Fadly. Faerozi and Anuparb finished sixth and seventh ahead of the best wildcard of the day, Sigit Purno Harjorno, who was 1.5 seconds clear of Anggi Setiawan, Richard Taroreh, Peerapong Boonlert and United M-Mate’s wildcard, Yossie Legisadewo.
