Some forums say "don't lube cables, they are made to not be lubricated" or "the lubrication will attack the plastic liner and destroy the cable". I have lubed every cable on every bike I have ever owned for the last 40 years. What should I do for my 2010 F800GS? I have the proper tool that clamps onto the cable allowing you to inject "lube" from the straw on the can. I have lube made for cables, but I always preferred Tri-flow. I also have this new DuPont Chain lube (O ring safe) which is beautiful stuff. Goes on wet and drys real nice leaving a Teflon coating. (the matching cleaner worked real nice to remove the factory crud, I mean chain lube). To lube or not to lube (and what to use), that is the question.
