This is super-duper general purpose light lube that is good for
a wide range of things, including cable lube:

Bike (bicycle) stores have it, and I've seen it in numerous
motorcycle shops...
My throttle cables were so draggy when I got my Valkyrie in 2006 that I ordered
new ones. In the meantime, I lubed my draggy cables with Tri-Flow... I still
have the new cables in the box and the previously draggy tri-flowed cables are still
working great.
As an aside, I lubed my choke cable and now the choke won't stay on... be
careful there...
