You didn't mention what year your bike is. I have the EBR chain rub and while it sort of conforms to the swingarm contour on my '04 XB, it's not an exact, perfect fit, and doesn't lend itself well to a suitable means of affixing it to the swingarm. The EBR web store says it works with all years of the XB, but it doesn't play well with the '04. It might work better with later models with the updated swingarm.
