Honda GN4 is the OEM-recommended engine oil for a wide range of Honda powersports applications. Formulated specifically for motorcycles with wet clutch systems, GN4 provides reliable protection against wear, heat, and friction — keeping your engine running clean and your clutch engaging smoothly.
Recommended for Honda Grom (all generations), Monkey (2019+, 2022+), Z125 Pro, CRF110F, and other small-displacement Honda models. Always verify your owner’s manual for the correct oil specification.
