Yamaha completely dominated the IRRC this year, winning in all classes (250cc, 150cc, 125cc and 110cc). For the Jupiter Z1 injection models, the motorcycle and Yamaha riders dominated the podium. Starting from the first round, Yamaha rider Anggi Permana riding a Jupiter Z1 model was on the podium, and from the second round to fourth rounds,Rheza Danica was consistently at the top of rider table in the 110cc class. Although absent in the final round, Rheza finished the championship just behind winner Irwan Ardiansyah on points differential. In the 110cc class, Galang Hendra on a Jupiter Z1 also dominated but unfortunately crashed in the final round. In the last round, the Yamaha community was well represented, with members from Yamaha Riders Federation Indonesia (YRFI) supporting the Yamaha Racing Team at the event.
