The cable lube posts pop up on this site from time to time and I always chime in with my controversial opinion Blah
I do not lube my cables... ever. I know most people on here do, but I believe that lube attracts dust/dirt and eventually cables gunk up. I am basing this on mountain biking experience, which obviously is not a direct carry-over to road motorcycles.
But.. I've never lubed cables on any of my bikes. Current one is a 07 FZ1 with OEM cables.. approximately 30k miles. Never been lubed. Smooth as brand new.
Not trying to convert or convince anyone, but just wanna put it out there.. not lubing cables will not necessarily make your motorcycle spontaneously combust.
