I have '02 ST4S and was advised by Frasers Homebush (Sydney Ducati dealer) that Regular fuel is all that should be used for general use - I had been running premium but at the first service this dealer even went to the trouble of draining tank and replacing with Regular. I guess serious track work the advice might be a little diffent but for day to day running Regular is the go.
In the past - 750SS, GPZ1100, R90S, Z1 900, CB360, TM250
