Bel-Ray V-Twin Primary Chaincase Lubricant 1 Liter

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

• Formulated to withstand high pressures and flow freely for improved clutch cooling
• Prevents clutch slipping and chatter for consistent, positive engagement
• Reduces compensator chatter for quieter drivetrain operation
• Exclusive Bel-Ray anti-wear chemistry extends primary chain service life
• Superior oxidation protection for extended drain intervals
• Distinctive red color for quick leak detection in multi-cavity drivetrains
• Meets or exceeds V-Twin OEM primary chaincase lubrication requirements — will not void factory warranty
