"Mineral", or conventional oil is made from refined crude oil, from the ground.
Synthetic oil is man-made and is superior. It offers greater lubricity and lasts longer.
i recommend u 2 use fully synthetic oil in ur bike u will feel the difference.
i recommend u (ZIC 4T FULLY SYNTHETIC , JASO-MA)
Actually in bikes we have wet clutch so we cant use synthetic oils in it. Because it will ruins the clutch. Butt which synthetic oils that have JASO-MA grade can b used with bikes. Which one is ZIC 4T.
