RED LINE SYNTHETIC OIL - 42904 - V-Twin Primary Case Oil - 1 US quart
The RED LINE SYNTHETIC OIL 42904 is a purpose-built oil designed and tested to perform correctly in the conditions and applications it was made for. For 1984-to-present V-Twin American motorcycle engines, including M8, Evolution, Twin Cam and aftermarket engines of similar design. Same fluid as our famous MTL gear oil, giving you a level of quality that holds up across the full service life of the component. Improves clutch operation while reducing wear and temperature. Where most synthetics are too slippery for clutch operation, this friction-balanced product is balanced to provide less slip, smoother operation and helps to apply more power in modified engines. This product is for use in the primary chain case with wet clutches. For riders who know the difference quality components make, the 42904 is the right call. Sold individually.
