I use the Mercedes brand coolant (re-labeled Zerex G-05) in my aluminum engine cars, and often debated on switching them to Evans too. The prep work is a lot of work so I've never switched.I recently switched to Evans water-less coolant. I am very happy with it.
It is pricey and a bit of a process to use, but after that it never needs to be changed again.
As with all of these coolants, the bike running cooler is negligible depending on the climate you live in. Evens has a lower freezing temp and higher boiling point.
I would not necessarily put it in my car. If I decide to build a car, then I would use it.
Now on the V-Rod, that's a good idea. Much smaller system, no heater core etc...
