A quick glance at the parts diagrams courtesy of Motorcyclespareparts.eu, I looked at 2007, 2012, 2015 and 2018. 2017 is 4231006G50, the others were 4231006G60.
So except for the 2007, they're all the same part number.
However, how much they may differ (slightly) in foot shape/design, I don't know. I bought a foot plate from eBay for mine, and it doesn't fit. Allegedly for a DL650. Granted, that doesn't mean much!
