Dalla Porta entered the Thai GP with a two-point advantage over Spaniard Canet.
It was a marginal gap with five races left in which to compete, including Thailand, until the season finale in Valencia.
In a turn of events at the Thai GP, Canet was clipped by Darryn Binder on Turn 12 mid-race after having won his home grand prix just two weeks prior.
The contact caused Canet to crash, triggering a domino effect that also took down John McPhee and Tatsuki Suzuki.
While no riders were hurt, Canet’s fight for the championship lead was damaged at a critical point in the competition.
The incident was immediately reported as “under investigation” and several laps later Binder was given a “ride through penalty” (ride through the pit lane) for “irresponsible behaviour”.
Binder misunderstood the instruction for a “long lap penalty” and consequently rode through both penalties, dropping from seventh position to second last.
In a repeat of the Misano GP events, Canet desperately attempted to re-join the race to no avail, finishing out of point contention.
Tony Arbolino, currently third in the championship, also struggled during the Thai GP, appearing to have mechanical difficulties on Lap 10 when he sat upright around a corner.
It was later discovered he was suffering from a physical hand injury, and although he dropped positions throughout the race he managed to finish 10th to gain six points.
Dalla Porta managed to lead the pack after just five laps in, after starting in ninth position on the grid.
The final lap saw an exciting sprint between Alonso Lopez, Dalla Porta and Albert Arenas around the last corner.
Dalla Porta fired in, in an attempt to overtake Arenas who led.
However, he went wide and Arenas crossed the line first.
“I did a small mistake and he won,” Dalla Porta said.
It was an important podium finish for Dalla Porta who gained a clear 20-point advantage and a 22-point gap from Canet.
Dalla Porta currently leads the Moto3 championship on 204 points, Canet is in second on 182 points and Arbolino is in third on 161 points.
Dalla Porta dedicated his podium to his grandmother, after revealing that she had died that weekend.
