Red Line V-Twin Primary Case Oil

Everyone thinks about the transmission side, but the clutch and primary chain need love, too.

• For 1984-to-present V-Twin American motorcycle engines, including Milwaukee-Eight, Evolution, Twin Cam and aftermarket engines of similar design.
• Same fluid as our famous MTL gear oil.
• 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 chaincase with wet-diaphragm spring clutches.
• Suitable for primary case in older British bikes.

Full-synthetic formulations specific to the latest V-Twins, UTVs, ATVs and Sportbikes.
