After years of development, Honda’s first fully synthetic four-stroke motorcycle oil offers many advantages over conventional oil, including:
- Oxidation resistance
- Higher film strength
- Better flow at low temperatures
HP4S is approved for use in all 2006 or newer motorcycles, ATVs, Scooters and PWC.
Compatible with synthetic blends like HP4 and regular petroleum oils like GN4, so there’s no need to flush the crankcases before switching to HP4S.
