If that's not your bike, then additional description of what it has would help -- 2012 is old enough that literature isn't easily available anymore. And it's likely not from the US market, which generally makes finding information about it more difficult. Here's something from
Giant's Australia website, but those have numbers following "XR" (like 0 or 1) and you didn't list that with yours, so it's hard to tell what it might be.
