The SE5 has a very particular clutch. Not all motorcycle rated oils will work well with it. Some have used an oil that worked fine in their previous 2 wheeled, wet clutch motorcycle. Only to find out that it slipped the clutch on their SE5. I don't know if it has something to do with weak clutch springs or clutch disk compounds used. I suspect a bit of both. But I can tell you that it is quite an expensive proposition to replace that clutch pack. Some of my customers caught the problem right away, changed oil and were fine. But many don't notice the clutch slipping until it is too late.
The JASO rating is a measurement of relative friction being created at the clutch plates. This is how it breaks out from the lowest friction rating to the highest. Highest being best for the clutch. The lower in the rating you go, the more you risk clutch slippage.

MA1

MA2
This rating pattern, to me, is a bit confusing. I would think that MA1 should come after MA. But when you read the technical articles about how JASO ratings are determined, it make more sense. But you can bypass all the unnecessary jargon by following these simple guidelines.
Once you've found a suitable viscosity (5w-40, 10w-40 or 15w-40). Or, for very hot climates, even a 20w-50 is ok Then look for these 2 ratings. In my opinion, you really want a JASO rating of MA2, as mentioned above. And you also want to avoid any oil that is SM rated. The SM rating indicates that friction modifiers have been added. Great for everywhere that you don't want friction. Which is everywhere but the clutch. While it is true that some SM rated oils will work fine in the SE5 clutch. If you are not sure of a particular product. I highly suggest passing it by for a non SM rated oil.
Treat the SE5 clutch right and it will last the life of the vehicle. I've got several customers with well over 100,000 miles on their SE5 with zero clutch problems.
Bottom line, I would not recommend any lubricant for the SE5 that was less than JASO MA2 rated. Because even within each rating there is a spread. Some lubricants may just barley edge into their given category. Whereas others may be at the top of that category. Getting a JASO MA2 rated oil means that even if it just barely made the cut, it's still good to go in the SE5. Anything else means you may be playing the test bunny with your Spyder.
It seems that BRP has fixed this situation in the SE6. That clutch pack is much more forgiving.
