This torrent contains the Round 12 of 2014 MotoGP Season (only main MotoGP category race) at Silverstone circuit in England, the same circuit that holds Formula 1 (except for the starting line place where it used to be Formula 1's some years ago) with Brazilian commentaries by Guto Nejaim and Fausto Macieira on audio track 1 and BT Sports's commentaries crew on audio track 2.  

Attention: That's my first experiment with dual audio on MotoGP, celebrating british commentaries on British GP (what a coincidence o/). As there is no commercial brakes unlike IndyCar which I took advantage on resyncing, if you still think it's still unsync, on VLC Media Player you can adjust by pressing J or K hot keys. I believe, though, it was fine.
