Designed by Spectro in response to complaints from Harley owners about the greatly operating but noisy new 6-speed transmission as fitted from 2006 to present in the Dyna and 2007 to present in Softails and Touring models. Formulated to significantly reduce gear noise and provide easier, smoother shifting, this API GL-5 rated SAE 75w140 formulation eases shifting even when cold. This full synthetic provides ultimate lubrication protection. High loads and extreme heat do not affect the oil, so it performs well when pushed hard and long.
