I hate to sound like a naysayer but it is doubtful that Victory will make a backrest specific to the XR-LE but if they do it would be much more money. The problem is that the backrest they already have can be on any 2010-13 XR, XC or XCT and the XR/XCT both outsell the XR by more than 10 to 1. Basically there aren't enough XR-LEs to make it worth it to them.
You have options that will cost you much less or close to the same as a leather backrest would cost through Victory. The cheap option is to find an uphostery shop that works in leather and have them match your seat then cover a OEM backrest (Cycle Ops can most likely do this too). The higher dollar option is to order a Corbin seat and thier backrest which would allow you to pick a new leather pattern/color which would be used on the seat and backrest.
