Red Line V-Twin Primary Synthetic Case Oil with Shockproof

This Polyol-Ester based Primary (70W80) oil is deigned specifically for 84 to present big twin style motorcycle engines, including aftermarket engines of similar designs. This product is for use in the primary chain case with wet-diaphram spring clutch.
Designed to operate over a wide temperature range, this product improves clutch operation while reducing wear wand temperature. Where most synthetics are too slippery for clutch operation, this friction-balanced product provides less slip, smoother operation, and helps to apply more power in modified engines.

For 1984-to-present V-Twin American motorcycle engines, including Evolution, Twin Cam, and aftermarket engines of similar design
