Designed by Spectro in response to complaints from Harley owners about the great but noisy new 6-speed transmission, this full synthetic provides ultimate lubrication protection. Formulated to significantly reduce gear noise and provide easier, smoother shifting, this SAE 75w140 formulation eases shifting even when cold. High loads and extreme heat do not affect the oil, so it performs well when pushed hard and long. API GL-5 rated.
