Anyone hear of Opti 4?

Calgary AB
I've used Optimol Opti-4 quite a bit in a 2000 Yamaha WR400F. It's marketed mainly for four stroke off-road motorcycle/ATV use. Worked great with the wet clutch. The OEM spec's an SG oil for the cllutch/tranny, imagine Opti is something like an SG oil, no FM. It's marketed as a premium product, I never had any need to use anything else.
