Locked in a tight tussle for the title with team-mate and championship leader Hari Krishnan Rajagopal going into the final round, Sethu, returning from a major hip injury, kept his wits about him to win both the races to clinch the title.
Hari Krishnan was under pressure to stay in front and had a disastrous weekend as he failed to pick up any points.
Jagan, though, had to work hard for his second win this weekend as he was pushed for much of the six-lapper until he managed to get his nose in front in the latter half to take the chequered flag before doing a lap of honour to celebrate his fifth National title in a row.
Equally dominating was Auroville-based Spaniard Ami van Poederooijen of Rockstar Racing in the Super Sport Indian 300-400cc class as he completed a double for seven wins, six of them in a row. He had sealed the championship on Saturday after winning the first of the two races, but that did not stop him from further underlining his dominance by topping the second outing today.
