Great spirits have always encountered violent oppositions from mediocre minds.

Found it! FYI - Red Line V-Twin Shockproof transmission oil is full synthetic, reduces gear noise & shock loading / lowest coefficient of friction available for improved power transfer / 40% lower coefficient of friction and 250% of the load carrying capacity of conventional gear oils. Produces more viscosity at high temps to prevent metal to metal contact & low viscosity in cold conditions for less friction and low drag. It is compared to 75W250 gear oil, providing 3x the viscosity in the thin layers between the gear teeth with the lower internal fluid friction of a 75W90 gear oil. Shockproof cushioning effect allows use of lighter viscosities with little sacrifice in durability.

Bottom line: it has lubricating properties of a 75W250, but its flow is a 75W90.
