What about this stuff?whttp://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_MX4T_10W-40.aspxhat about this stuff
I go to Mobil 1, 15W-50 at the first oil change -- have done that for the past 28 years and almost as many bikes with NO problems.
Go for MOTUL 5100, if you can buy it where you liveI use it and most the Suzuki racing superbikes use this brand alsoGood oil, not too expensive
