125cc World Championship leader Nico Terol utterly dominated Sunday's Indianapolis Grand Prix.

The Aspar Aprilia rider, whose title lead had been slashed from 32 to 12 points after a technical problem at the previous Brno round, bolted from pole and was over ten-second clear of the field by the halfway stage.

After cruising the final few laps, Terol went on to win his sixth race of the season by 3.633sec.

Joining Terol on the podium were rookie Maverick Vinales (Paris Hilton Aprilia) and Sandro Cortese (team German Aprilia), who locked horns with Sergio Gadea (Paris Hilton Aprilia) for much of the race.

With Terol's nearest title rival Johann Zarco finishing just fifth, Terol's advantage is back up to 26 points heading into next weekend's Misano round.
