Your Harley wants better raw materials and more ZDDP than other brands offer. This 20W50 Motorcycle Motor Oil is full synthetic with PAO and Ester base stocks and 2200 ppm of ZDDP for antiwear. Full Synthetic 20W50 Motorcycle Motor Oil is designed for the latest Big-Twin motorcycle engines that specify 20W50 motor oil, including Evolution, Twin Cam, and aftermarket engines of similar design. It has superior film strength through the use of ester base stocks for protection and ring seal, extended drain intervals over other brands due to higher quality base stocks and excellent dispersants, and is blended with specific friction modifiers that are compatible with wet-clutches, suitable for JASO MA applications.

• Reduces thinning from high temps
• Higher levels of anti-wear chemistry like zinc & phosphorus
• Special friction modifiers for wet-clutch operation
• For four-stroke motocross bikes, ATVs, Sport bikes, V-Twins, & JASO MA applications.
