After 100 hours on the Sherco 300 SE factory, it's past due on some suspension bearing maintenance. We use the Motion Pro Deluxe kit to get out a couple seized bearings and replace them with new OEM bearings. The linkage wishbone was the biggest issue I ran into. The bolt was so seized we had to use an air hammer to get it out. The bearings were basically welded into that part. I had to actually buy a whole new piece that came with bearings already installed. We went ahead and replaced all of the other bearings including the swingarm bearings to get ready for the upcoming 2024 race season. Hopefully you find this helpful!
