National Cycle clearly lists it for "Yamaha 1300cc,XVS1300 V Star/Tour 2007 to 14". I don't know why those other sites wouldn't list it unless they have old information. Case in point is Amazon. They don't even list a single motorcycle for the part after 2008.
On the other hand, Cruiser Customizing has no problem listing the part as fitting your bike.
You could always just call National Cycle, too: 877-972-7336
