T4 is the Dino Oil. Delo Dino and 5w40 Synth has no Jaso MA certs that I know of. It may work fine though.
And the above Dude, Yah, those put way more stress on a clutch than a rear wheel.
I don't think Jaso MA certs cover clutch grab when turning a track compared to a tire.
I have the new bottles of T6 in many bikes, no issues.

Husky. Real Expensive. But my bike only takes 1.1L at a time. seems to be real good stuff. Never got on the rotella train. Seems to be just as mixed review as what to mix gas at for a 2 stroke.

It has both JASO MA and MA2, the 10w30 T4 doesn't have the MA rating.
T5:
Neither 15w40 or 10w30 have the MA rating.
Looks like spec wise T4 15w40 is the only one that has the MA rating. I run T6 or T4 depending on which one I have on the self when I'm changing the oil (I run the T6 in my TDI). Never had any problems on my Maxim X or dirt bikes. Funny people always have to jump in and say motorcycle specific oil, the only oil I've ever had gel up on me was simi synthetic belray 4 stroke oil... I ride in deep sand often in ambient temps above 100°. The rotella oils are made for turbos, so they have good oxidation resistance.
What is the difference between JASO MA/MA1 and JASO MB?

What does the JASO MA and JASO MA2 Standard Mean?
In 1998 the Japanese Automotive Standards Organization (or JASO for short) developed a grading system for motorcycle oils.
The grading system measured (amongst other things) an oils ability to resist clutch friction (or slippage), protection offered against engine wear and pitting in the gear box.
Up to 1998 car oils had been used as the base for many motorcycle oils. As car technology evolved over the years the oils that cars needed changed and additives were added that weren’t good for motorcycle engines (especially motorbike clutches and gearboxes, mainly due to the fact that, unlike most motorcycles, cars use a separate oil for the gearbox).
Car oils had been blended using more and more friction modifiers, which, although good for cars, wasn’t too good for motorcycles as these modifiers can cause clutches to slip at higher revs and gearbox pitting.
JASO introduced 2 ratings for 4 stroke motorcycle oils:
JASO MA – This was the standard for single unit engines where the wet clutch, gearbox and engine used the same oil.
JASO-MA oils don’t contain friction modifiers.
JASO MB – This lower standard was for bikes that use separate oils for the engine, clutch and gearbox (e.g Harley
Davidson’s and BMW’s).
T4 15w40 and T6 5w40 are all Jaso DH2 MA MA2
T5 10w30 semi synth are no go. Again formulated for mileage.
