That stuff can really bugger-up the works in a cartridge fork but not so bad with normal damping rods.  Even with damper rod forks, I still clean it out because it helps reduce wear and increase life on the seals.

Good point, when I replaced fork oil on the 2015 CB500X purchased November 2015, it had less than 2000 miles and the old oil was very dirty!

Still plan to use the extractor for motor oil on the bikes with skid plates. Always looking for ways to reduce maintenance time.

How often does everyone change fork oil?

After seeing how dirty the CB500X fork oil was after about 2000 miles during fork spring change on a 2015 model, seems like fork oil should be changed much sooner, at least the first time. My operators manual does not include fork oil replacement in the regular maintenance chart (don't have a FSM yet), reading on line recommending 10,000 to 20,000 mile intervals and one to two years for various bikes.

Looks like changing fork oil more often would reduce suspended particles, sludge build up, and overall component wear. Would probably change fork oil and clean springs/spacers more often using a oil extractor, since it's easy. Can still disassemble complete fork assemblies & clean components at recommended intervals. Overall this practice would reduce component wear and parts replacement.

NEVER!.....Gotta love the BMW telelever suspension!

That's a neat looking system. Had to google it, since I'm not a BMW owner, yet!
