Ya, so far I’ve got about 500 miles on the M1 20w50 and it feels great so far. These Victory 106’s are known for somewhat notchy shifting compared to other bikes. But I feel like it feels better than it has before by a slight margin. Not that it’s buttery smooth, it will never be just based on its design.M1 20w50 V-Twin has 1600 phosphorus 1750 zinc as stated above, and did a GREAT job for over 5,000 miles on an OCI in my ZRX1200. Stayed in grade, plenty of remaining TBN, and shift quality was as good as the day it went in, IMO. As far as I am concerned, both flavors of M1 (V-Twin and 4T) are hard to beat when used in a proper grade for bike it's used in.
This Schaefer's discussion is interesting, and it could come down to whoever wrote that was coming off of a party night and just didn't quite hit the keystrokes right, lol.
I didn’t post the whole email and who it was from, just a portion of it. I didn’t want to open a can of worms or point fingers at anyone specific or a company many like in this community. But here is the email response (below) I received and copied/pasted from their Chief Chemist/Tech Director. But this makes it all the more confusing since it is MA2 rated somehow (regardless of the zinc or phosphorus). Yet the Chief Chemist claims it can’t be used in a wet clutch application. How did it get an MA2 rating if it can’t be used in a wet clutch? Ugggh. It claims moly and Penetro is the reason it cannot be used. I’m glad I’m not the only one confused by this as I am a novice in oil tech, but I know how to read. Lol This subject almost requires it’s own thread.
“The 707 cannot be used in Victory motorcycles. The Victory bike call for the use of an oil that meet JASO due to the wet clutch. MA type oils cannot contain any frictional modifiers such as moly or Penetro. Also MA type oils cannot contain high amount of zinc dithiophosphate. All of these materials can cause the clutch materials used to not properly lock up in the required amounts of time resulting in slippage and poor shifting.
Schaeffer does not have an oil for this application.”
