Come the ARRC Official Tyre Test on December 4, the Yamaha Thailand Racing Team will be putting newly crowned SuperSports 600cc Champion Ratthapong Wilairot and Anupab Sarmoon through their paces astride the Yamaha R1.
It will be a brand new challenge for Ratthapong Wilairot, coming straight on the heels of his SuperSports 600cc triumph at the same circuit. Wilairot has shown dramatic improvement since he donned the Yamaha blue early this year.
By 2019, Ratthapong will be 27 years old while Anupab will turn 26. With the new age limit imposed, both riders are no longer eligible for the SuperSports 600cc.
