Their chart shows it fitting 2008-2009 EX250J. Not sure why not later years as 2008-2012 is the same.

There's also this one which shows as fitting all new-gen 2008-2012: https://www.ebay.com/itm/362446119559

Post picture of what part doesn't fit and why. Might need an extra washer.

Sorry for the late reply but i can't find some picture to see the front sprocket until today, but i don't know why but the sprocket and chain won't fit, because the clutch cover is big, and when you put the chain, the sprocket cant move, here is a picture, i hope you could understand the yellow line is the chain and the red line is where the bike won't fit for the clutch cover, and the red circle is the "sprocket"
