Red Line 20W60 High Performance Motorcycle Oil 12604 – 1 Quart

Red Line 20W60 Motorcycle Oil 12604 is a full-synthetic motorcycle engine oil specifically formulated for air-cooled V-Twin engines that require a heavier viscosity. It is an excellent choice for motorcycles operating in extremely hot climates or engines with wider internal clearances.

This oil is particularly popular for Harley-Davidson® Evolution and Twin Cam engines, including applications with big-bore or stroker kits and engines experiencing valvetrain noise. It is also specifically formulated for traditional air-cooled V-Twins such as Knucklehead, Shovelhead and Panhead engines.
