It is strange, but many XR owners have reported about the length of the negative battery cables (too short), while other owners (me included, fortunately) have reported that the cable length is not an issue at all. Strange.............................BTW , if you intend to pull the battery out completely , you might want to obtain a longer ground cable first .
The stock one is a mite short and makes re-installation an exercise in not enough hands , not enough room ,
and not enough patience .
IMO ( and others on here ) .
