Primary Chaincase Lubricant – Bel-Ray (1L)

Bel-Ray Primary Chaincase Lubricant is a premium-grade transmission oil specifically designed for the primary chaincases of all "Big Twin" motorcycles. This lubricant is optimized to withstand high pressure and ensure smooth clutch operation, significantly extending the service life of the entire mechanism.
 

Key Features:

• Maximum Protection: Bel-Ray’s exclusive anti-wear chemistry effectively protects the primary chain and sprockets from wear and stretching.

• Smooth Clutch Operation: The formula prevents clutch slipping and "chatter," ensuring consistent and predictable engagement even during intensive riding (e.g., in heavy traffic).

• Distinctive Red Color: The bright red color allows for easy and quick leak identification, helping to distinguish this fluid from engine oil.

• Thermal Stability: A high viscosity index ensures reliable performance in both low temperatures and hot climates.
