wow, it looks as though H-D is marketing their own low-SAPS oil.
It's nice and viscous though.

Relying on boron to do Zinc and phos's job, which works I guess.

Flashpoint of 510 F.
This is a 20W50.
I don't think I've seen higher.
Red Line lists Flash of 490 for their 20W50 Motorcycle oil.
M1 lists 417 F for their 20W50 V-Twin Motorcycle oil.
