Yet another confirmation that the OEM m/c brand oils are mundane, to say the least. OTOH, the "premium" stuff is WAY overpriced for what you get as well. Just another reason to run some good HDEO and call it a day.
But to put things in perspective, I have a good friend who has a 1995 ST100 with over 125k miles on it now, and has had dealer serviced Honda conventional oil and filters since new. Apparently, even though that stuff is "mundane", the engine just doesn't seem to care.
