Honda's HP4S Synthetic Motorcycle Oil is engineered by Honda R&D for severe duty and racing applications. This extreme duty formula is designed to offer maximum wear protection during both cold start period and high rpm use. Its shear stable polymer additives provides smoother shifting and reduced friction and in turn affords better fuel economy, reduced temperatures and minimized wear.

Honda set the standard for motorcycle oil when it introduced GN4 in 1975. We selected the highest-quality base stocks, and created an additive package specifically designed for the unique requirements of motorcycle engines. We still do. Constant testing and development has given today's GN4 even better shear resistance, viscosity stability and cleanliness to meet the requirements and stresses of a new era of engine technology.

This is the top of the line premium 4-stroke motorcycle oil and is recommended for all "normal" riding situations. Normal riding situations are when the motorcycle or ATV is used as designed and is not "lugged" or run near redline for extended periods of time. HP4 is a blend of synthetic and petroleum base stocks for excellent oxidization reduction, less evaporation, shear stability for smoother shifting and less viscosity loss. HP4 does not contain moly.

Formulated for high heat, 4-stroke motorcycle racing applications only. If the bike is used for high performance riding and it will be operating at or near redline for extended periods of time, this is your oil. HP4M with Moly is a blend for synthetic and petroleum base stocks. The synthetic portion is very effective, in high heat applications, at reducing oxidization, evaporation, and viscosity loss. It also contains molybdenum (moly), a very slippery substance. The moly contributes to less friction and heat in high temperature situations, therefore allowing the motor to rev easier, creating more horsepower!  So if horsepower is your goal; HP4M is your oil.

The Ultimate in Performance and Protection

HP4 0W30 ATV oil is a super premium oil formulated in the tradition of excellence by Honda Research & Development specifically for the cooler Canadian climates.

Hi-Performance Synthetic/Petroleum Oil without Moly sets a new standard for premium 4-stroke ATV oil.

Pro-Honda ATV oil is approved for use during break-in period, and exceeds all new Honda ATV warranty standards.

Exclusive additives give maximum wear and protection during the critical cold start period, and during high RPM use.

Better low temperature fluidity for easier cold weather starting.

High-performance racing transmission oil specially formulated for all Honda CR models. Transmission gears can whip conventional oil into a froth, and intense pressure at their teeth can lead to metal-to-metal contact. HP Trans Oil offers ultra-high film strength and shear stability to minimize transmission wear, while its high thermal stability prevents foaming and premature oil breakdown. Special anti-friction additives allow smoother shifting, while minimizing drag and power loss. Anti-shear additives increase clutch life, reducing clutch slippage.

If your CR is operating at or near redline for extended periods, this is your oil. HP2 features 100% premium synthetic base stocks and special additives to protect against wear, friction, and heat for cooler running, maximum horsepower and quicker throttle response. The extremely clean-burning formula extends spark-plug life, reduces carbon deposits, and maintenance intervals on CR Power Port and ATAC systems.

Pro-Honda GN2 has been tested and approved by Honda R&D for use in all liquid- and air-cooled 2-stroke Honda motorcycles, scooters and ATVs.  Its unique clean-burning formula reduces exhaust smoke, carbon buildup and varnish deposits, and helps prevent spark-plug fouling, ring sticking and exhaust plugging. GN2's superior lubrication extends service life for piston rings and bearings, and helps protect against rust and corrosion.
