Live UK coverage of the MotoGP World Championship will switch to BT Sport from the start of next season.
An exclusive five-year deal for BT's soon-to-launch sports channels was confirmed during a presentation in London on Thursday morning.
"We're proud that MotoGP will be part of such a huge and exciting project as BT Sport," said Manel Arroyo, managing director of MotoGP's commercial rights holder Dorna Sports.
"I'm sure that BT Sport will provide the in-depth coverage that MotoGP deserves and in turn MotoGP will provide the sporting drama and excitement to help launch BT Sport as a major player in the TV market."
While the exclusive nature of the deal spells the end of the BBC (free to air) and British Eurosport (subscription) live coverage, it was soothed by the surprise news that all three BT Sport channels - BT Sport 1, BT Sport 2 and ESPN - will be available free of charge to BT Broadband customers.
"UK Sports fans have had a rough deal for too long," said BT chief executive Ian Livingston. "Many have been priced out of the market but we will change this by giving away BT Sport for free with our broadband. Sports fans are the winners today."
BT Sport will be available via BT's own TV service, on Sky's digital satellite platform and online, including through a mobile App.
The cheapest Broadband deal currently advertised by BT is £10 per month, rising to £16 for unlimited data usage. Non-BT Broadband customers will need to pay £15 a month for the BT Sport channels, which compares with £85 for a season of live video coverage on the official MotoGP website.
'MotoGP fans won't miss a minute of the action as race weekends will be covered in full starting from the free practices on the Friday and including full coverage of Moto2 and Moto3 as well as the elite category MotoGP,' read a BT Sport statement.
'Coverage will be hosted on-site with additional studio coverage from BT Sport's state of the art facilities at the Olympic Park in Stratford, East London.
