Can you use ATF in Harley transmission?

We submit that ATF is too thin for Harley primary use. It’s true that many Harley riders have had years of problem-free performance with ATF. We contend that a thicker oil will provide superior metal-to-metal wear protection. Chains and sprockets will last longer using a fluid with an appropriate viscosity.
