This is due to new EPA rules:mad: They have been working on this for a while and I think Harley has staved them off for a some time but aircooled will soon go the way of the 2 stroke:confused: even for H D

Liquid cooling maintains a more consistent temperature, so you have more efficient combustion, fewer emissions. That's the simple version from a non-engineer. We only change the coolant once every few years, so a few quarts to dispose of then is not nearly as much of an environmental factor as the amount of emissions every time the engine is running.
