Engines built in the 1960s and earlier with leaded gasoline in mind can benefit from a lead substitute to help prevent valve recession and engine knock.
Motorcycle oil and dirt bike oil must be formulated with the correct frictional properties to ensure smooth, consistent shifts and long wet clutch life.
