Last month the broadcaster announced plans to offer viewers seven camera views online and via the app, in addition to its main coverage on TV.
Coverage starts on March 18 with a special preview show featuring interviews with all the top riders and action from the key official pre-season tests.
In addition to live broadcasts of practice and qualifying sessions and races from the FIM MotoGP season, BT says it will bring fans “full coverage” of the Moto2 and Moto3 races.
Viewers will be able to choose between seven camera views, including four cameras fitted to bikes, a helicopter view and live timing and tracking screens. Full races and highlights including interviews and features will also be available to watch.
The app is only available to BT customers who get BT Sport free with a broadband package or Sky TV customers who pay the ISP directly for the channels.
Plusnet and Virgin Media customers are ineligible to use the app and so won’t have access to the extra camera views.
The updated app will be available to download for iOS and Android powered devices from Wednesday.
