My Suzuki owners manual states to use; 10w-40 API SF or SG, or SH, or SJ
You can use higher letters than recommended without any bother, they reflect improvements in oils after the book is written. So SN would be safe to use,
BUT as said, its not for wet clutch so don't use it.
Dry clutch would be ok though and I quite happily use them in my K bikes. I am taking yet another one of them over the 100,000 miles this month and never a problem.
Regular oil changes and good oils. Remember selling oil at that price is a loss leader to get you in the door, not a cheap oil.
