British private investment company Bridgepoint Group is in advanced talks to sell Dorna Sports, which holds the commercial rights to MotoGP, in a bid to raise 3.5 billion pounds (US$4.43 billion), Sky News reported on Saturday.
MotoGP is the top division of Grand Prix motorcycle racing, the sport's highest class of events.
Bridgepoint declined to comment on the report.
Liberty Media, which also owns Formula One, is said to be the frontrunner to buy Dorna, although it is reportedly facing competition from a number of rival bidders.
Liberty Media also has publicly listed tracking groups for its interest in Formula One and event ticketing firm LiveNation.
Dorna Sports and Liberty Media did not immediately respond to a Reuters request for comment.
London-listed Bridgepoint, which owns close to 40 per cent of Dorna, is trying to close the deal within few weeks, Sky News said citing a single source. (US$1 = 0.7905 pounds)
