The bottle I bought last year lists JASO MA, just like this info sheet does too.
I have used T6 in both the Aprilia and Speedy with no issue. Pretty sure those make slightly more power.I used it as well. No clutch slipping either. That bike only makes 36-38hp. May there's a threshold?
Seems to me T6 has changed.

It wasn't SAE SM rated last year was it?

A friend had 60k on an 08 fireblade running T6 exclusively, original clutch showed no signs of slippage. But hey, if anyone wants to buy the "motorcycle" oil for more, by all means don't let any of us sway you
Isn't the T called T4 now?
I bought a pail about a month ago when it was also on sale. Think it was $68 or something. Worked out to just a bit more than Walmart brand stuff by the pail. Forgot about/didn't know about an extra rebate from Shell. Likely can't find the receipt now.
Will be running the T4 in my 944 (one of the few oils you can still get with the right amount of zinc for these older engines) and likely the CBX I'll be picking up soon. Might use it as a top up oil on my Outlander as it's getting high in mileage with a few leaks and a little bit of thicker oil might help it out. Tricky part now is how to get it from the giant pail into my vehicles as it's tricky to pour in that format and I don't have any smaller oil bottles around or any kind of oil pump...
