I have recently purchased an R6 rear shocker from Kebab19 for my FZS600. It has been one of the easiest jobs I have done. All in all took about 2 hours from start to finish. I gave the bolts a good spray with a well known releasing agent the night before. All bolts came off without a problem, I did check all roller bearings and re greased them before re fitting, and it all went back together without any issue. I am hoping that I have been able to attach a photo of the new item in place.
