Check the owner's manual. The bikes like that I have owned said to use motor oils of the specified viscosity and grade that do not have the API "energy saving" or "resource conserving" label. That label usually only appears on oils Xw30 and thinner. Most oils @x40 and thicker don't have it. But look just in case.
PS does the manual state that the oil must be JASO certified - like JASO-MA or MA2? None of the bikes I owned required that, but maybe some do?
I've used diesel engine oils in motorcycles with wet clutches without any issues, whether they have the JASO MA rat or not. If you want a good oil at low cost that has JASO MA on the bottle, I'd suggest Rotella T4 15W-40.
You can go to any store or online and search for "motorcycle oil" and get a lot of oils that are sold as motorcycle oils, but do not actually have the JASO certification label (will say something to the effect of "meets requirements of" or "recommended for" JASO).
You can use a HDEO/diesel oil (Rotella is the only current one I know of that does it still) that do not advertise as a motorcycle oil, but have the above language that it meets the spec without actually having the cert label.
Or you can use any oil in the correct (or close enough) viscosity that does not have the "energy saving" or "resource conserving" label on it.
In over 90,000 miles of riding with multiple bikes, I have never used an actual JASO certified motor oil (and all were bikes that were JASO bikes).
Lots of "recommended for" and "meets requirements of" oils, and even more just diesel oil or "car oil" without the energy saving label.
My current go to motorcycle oil is Mobil 1 10w-40 high mileage.
I know Castrol GTX 10w-40 (white bottle) was a popular oil to use by many for a long time, but don't see it mentioned as much.
