I have searched the Forum without getting the full answer...: What grade fork oil is used in the 2016 R9T (Up side down - golden forks - non adjustable)? If possible I want to "soften" them by using a lighter oil. I also plan to re-valve the OEM shock as it is a bit "harsh" on our African roads. Anyone here tried it? (I know there are better and much more expensive options available... but not suitable for a pensioner's wallet!) Regards!
