Hello! the title covers a lot of it, but my question is fairly simple. I have a 2011 R1200GS, ESA. 76,000 miles. I have an option to buy an ESA suspension from a 2009. According to the parts fiche, the part numbers are the same, but I did see there might be a difference on the front suspension, which is the external reservoir. so what do you guys think? Can I swap a 2009 ESA suspension into my 2011?
