Sarthak, who will turn 18 at the end of October, clinched the crown by winning Race-1, which put him beyond the reach of his rivals in the points tally. 

“It feels great to win my maiden National title. I’ve had a good season this year with five podium finishes at the Asian level. At the start of the season, I was focused on my riding and wanting to do well,” said Sarthak.

Later, Chiranth Vishwanath, the 17-year-old from Bengaluru, won the other premier class race, Pro-Stock 165cc Open, which went down to the wire. TVS Racing swept the podium spots with K.Y. Ahamed and Sarthak finishing second and third.

Meanwhile, the Girls (Stock 165cc) race threw up an unexpected result as the two championship contenders Ryhana Bee (One Racing) and Rakshitha Dave (RACR Castrol Power1 Ultimate) made contact and crashed in the third lap. Their retirement saw Jagathishree Kumaresan (One Racing) secure an easy win ahead of teammate S.P. Shuria and Saimah Ajaz Baig (Motul Sparks Racing).
