Pro Honda HP4S: New Pro Honda HP4S is Honda’s first fully synthetic 4-stroke motorcycle oil and was quite literally years in the making. HP4S is compatible with synthetic blends such as HP4, as well as regular petroleum oils like GN4. There is no need to flush the crankcases before switching to HP4S. HP4S offers lower friction than conventional oils, better oxidation resistance for better high heat performance, higher film strength and quicker flow to vital engine parts at low temperatures, especially during start up. And best of all, HP4S provides maximum power due to less frictional drag. HP4S is recommended for use in all 2006 or newer motorcycles, ATVs, Scooters and PWC. It is quite simply put… our very finest four-stroke oil.


Pro Honda HP4 Thanks to the establishment of JASO standards, HP4’s extraordinary additive package offers increased anti-foaming qualities, higher viscosity index for stability over a broader range of temperatures, and even greater shear stability than most other oils. Naturally, HP4 blends the heat stability and shear resistance of synthetic oil with mineral oil’s natural lubricity yielding premium quality four-stroke engine oil. Best of all, HP4 is approved for use in all Honda Powersports products.


Pro Honda HP4M A synthetic/mineral oil blend that combines the very best qualities of both types, HP4M also features a comprehensive additive package and friction-reducing molybdenum compound for smoother shifting, maximum fuel economy and peak horsepower. HP4M… the Pro Honda oil good enough to win a multitude of AMA National road-racing championships as well as the grueling Baja 500 and 1000.


Pro Honda HP2 Pro Honda HP2 is simply the finest 2-stroke oil money can buy. Premium synthetic base stocks with high film strength give maximum wear-protection, while allowing a crisp 32:1 mixture ratio. The extremely clean-burning formula minimizes carbon deposits, extends spark plug life and reduces maintenance on Honda Power Port and ATAC systems. Special additives minimize friction for cooler running, maximum horsepower and quicker throttle response.


Pro Honda GN4 Honda set the standard for motorcycle oil when it introduced GN4 way back in 1975. We selected the highest-quality base stocks, and created an additive package specifically designed for the unique requirements of motorcycle and ATV engines. As a matter of fact… we still do! Constant testing and development have evolved to give today’s GN4 even better shear resistance, viscosity stability and cleanliness to meet the requirements and stresses of a new era of engine technology.


Pro Honda GN2 Pro Honda GN2 is the only oil that has been tested and approved by Honda R&D for use in all older liquidcooled and air-cooled 2-stroke Honda Motorcycles, ATVs and Scooters. 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 prevent against rust and corrosion.


Pro Honda HP Trans Oil Cutting edge high-performance racing transmission oil specifically formulated for all Honda CR.® and FourTrax.® 250R models. HP Trans Oil is also the hot tip for use in all Honda CRF 4-stroke transmissions. 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 antifriction additives allow smoother shifting, while minimizing drag and power loss. Anti-shear additives increase clutch life, reducing clutch slippage.
