I read somewhere in the past that dealers for other brands sometimes use Honda moly 60 on shaft final drives...BMW, I think...which suggests it's pretty unique, but since the majority of *HONDA* dealers seem clueless about it, it would be surprising if that many other brand dealers/mechanics know about it.
I paid the "wopping" ten bucks or so for the Honda Moly tube years ago and I think it will outlast me and the bike. (Speaking of which: what else can we use this on?) I'm no expert but it does seem to coat the surfaces like no other lubricant. They might have sold more of this stuff, and created themselves a much bigger market, had they packaged this, say, ten times smaller.
