This high quality mineral motorcycle oil has been exclusively developed and tested for V-Twin engines (e.g. Harley Davidson). Its unique additive package helps prevent engine wear and ensures the engine to run cooler, cleaner, and free of sludge, varnish and corrosion. V-Twin motorcycles operate at higher temperatures than water-cooled engines, so a specific high temperature additive package is necessary to protect the engine.Originally developed and tested exclusively for use in V-Twin engines (e.g. Harley Davidson), this oil can also be used in older 4-stroke motorcycles. It is suitable for integrated gearboxes or wet clutch systems.
