Maxima MTL Transmission Oil
Simply the best. It is pure Esther synthetic. You can ride longer between oil changes, your engine stays cooler and your transmission shifts smoother. I only use Maxima Esther synthetic in my Wide Glide, not because it is necessary, but just because I like to spoil my bike and don't like my oil breaking down in high temperatures on long trips. And, of course, Motorcycle-Superstore always exceeds my expectations.
