Knight won World Enduro titles in 2005 and 2006
Manx Enduro star David Knight's return to the World Championship next season could spell the end of his five-year association with KTM.
Knight, who leads the Grand National Cross-Country campaign by 42 points, is "bored" by the series after he easily won the title in his debut season.
The Ballaugh rider says the challenge of a World Championship return will remotivate his riding.
"I've not put pen-to-paper yet, so it's probably going to be with a new team."
He added: "To go into next season and win a on a machine that has probably not won before will be a great motivator for me."
