Bel-Ray V-Twin Primary Chaincase Lubricant 1 Liter
Every time the clutch lever comes in, the primary chaincase takes the load — and the quality of the lubricant in there determines how smooth, quiet, and consistent that engagement feels. Formulated specifically for the high-pressure demands of Big Twin primary chaincase applications, this dedicated fluid keeps compensator noise down and clutch feel sharp across the full range of riding conditions.
Key Features

- Exclusive Bel-Ray anti-wear chemistry extends primary chain service life
- Superior oxidation protection for extended drain intervals
