Coming off a 2016 800GS I'm very happy with the 850 except the forks. Mine are either defective, lol or the forks just aren't very good. Ok, sort of ok on bigger hits and stuff. But washboard and little bumps, it's like they don't respond. Is this an issue or do I have a problem? Thinking of going to the aftermarket cartridge, just want to be sure that is needed and if it will help.
