Ellison has been struggling with massive chatter and is one of only two riders yet to score a point.
Speaking on British Eurosport’s coverage of Monday’s Oulton Park BSB round, Bird revealed that Byrne could take Ellison’s place at Le Mans and therefore make his first MotoGP appearance since 2005.
“It’s something I have been milling over for a couple of meetings,” said Bird. “James seems to be lacking a bit of confidence and is complaining about massive chatter with the bike.
“Obviously Shakey has ridden at Le Mans a couple of times and maybe we will let him have a run out on the bike and rest James for a meeting.
“That way we can have another view of what the bike is like, to see if we do have a severe chatter problem, but, you known, Casey Stoner has severe chatter problems and still wins the race, so we will have a look…
“I’ve asked James if he wants to run at Le Mans but I think we would get another view of what the bike is like. It’s our first [MotoGP] season so maybe it’s time for a management decision.”
Also Chris Vermeulen will stand in for Colin Edwards for the Forward Racing Squad in the forthcoming French Grand Prix at Le Mans.
