Golden Spectro is a super premium blended Semi-Synthetic lubricant. Exceeds all known motorcycle manufacturer's warranty requirements, plus A.P.I. SL/JASO MA/MA2. Smoother shifting, highest shear stability and exceptional endurance. This 20W-40 is great for use in both engine and transmission in all 1998 thru 2017 Victory and 2013 to present Indian motorcycles, except Indian Scout and Victory Octane. For these we recommend Spectro Platinum Full Synthetic SAE 15W-50.
