I've tried many different lubes over the years and recently have switched to using Dupont Teflon Multi Use. It goes on easily, doesn't make a mess, dries quickly and doesn't fling like conventional petroleum based lubes.
I was a Maxima Chain Wax convert for many years, but even that left me wanting a bit better lube for not flinging lube around while riding.
When I heard about the Dupont stuff, I was very skeptical, but after using it on the Ninja and even the dirt bikes, I'm sold.
So, what chain lube do you use and why?
