Cobra Clutch Milk is the official transmission and clutch fluid from Cobra Moto — formulated specifically for the unique demands of Cobra's automatic 3-shoe centrifugal clutch system used in the CX50 and CX65. This is not a generic gear oil or motorcycle transmission fluid: Cobra Clutch Milk is the only fluid engineered exclusively for this clutch design, and Cobra Moto mandates its use in their technical service bulletins.
The exclusive synthetic formula addresses the specific challenges of the Cobra centrifugal clutch. An advanced additive package keeps clutch debris from adhering to the clutch spring stacks — one of the primary causes of clutch performance degradation in high-cycle racing use. Critically, Cobra Clutch Milk contains no friction modifiers, which ensures excellent clutch hook-up and consistent engagement — friction modifiers in standard gear oils cause slippage in the Cobra clutch system. The low windage formulation minimises parasitic power losses within the transmission, delivering more engine power to the rear wheel.
Change interval is recommended at every ride or every hour of operation — the Cobra clutch system generates significant debris during normal use, and regular fluid changes are essential for consistent clutch performance and longevity. This 6x1L case provides a full season's supply for an active racer.
