HONDA MOTOR OIL 10W30 QT (PACK OF 2)

Honda's own 10W-30 motor oil is a straightforward match for the CB125r, which calls for exactly that viscosity grade in its owner's manual. Using the manufacturer's branded oil removes any guesswork around compatibility with Honda's wet clutch system, which shares oil with the engine. The two-quart pack covers a full change with a small reserve. Caveat: this is conventional oil, so riders who prefer extended drain intervals should look at a synthetic alternative instead.
