Just curious about the numbers of users using which weight. My 2020 Enduro says to use 10w-50. I hear the cam chain tensioner when the oil and ambient temps are hot. No running issues though. KTM 690, same engine, recommends 10w-60. I'm thinking of going to 10w-60 next. Consensus? I'm guessing the bikes with 10w-60 are quieter on startup in similar conditions compared to 10w-60.
