11 also has new fuel injection system, upgraded transmission, new speedo with temp guage and clock, redesigned gas tank, better roll bars, stronger frame and depending on when the 2010 was built if before 5-2010 it has the upgraded other tranny parts some 2010s are having break and the new metal front sprague. The resale on a 11 over a 10 would be more than the 500.00 difference soon as you take it home.
