Seven-time AMA Superbike Champion Mat Mladin, 37, seems to be implying that he’s considering coming out of retirement to accept a ride in the 2010 FIM Superbike World Championship. On December 9, Mladin posted the following on his Twitter page: “a couple of world superbike offers have come my way in the past month. 1 of them very good in regards to machinery. decisions decisions ;-)” Mladin, the 2009 AMA Pro American Superbike Champion and the winningest rider ever in the class, announced his retirement prior to the end of the season. He often spoke of his discontent with the new management and direction of AMA Pro Racing and told reporters that he had subsequently lost the motivation that had propelled him through much of his career. Mladin’s most recent rival, Ben Spies, moved to the Superbike World Championship in 2009 and won the title in his rookie season. Spies will race in the MotoGP World Championship in 2010. Mladin did not reply to an e-mail requesting clarification.
