Motul MC Care C4 Chain Lube Factory Line — 9 oz Racing Chain Lubricant, High-Adhesion & O‑Ring Safe

Motul MC Care C4 Chain Lube Factory Line is a high-adhesion, racing-grade aerosol lubricant formulated to protect O-ring chains while resisting fling at high speeds.

Designed for sport and competition motorcycles, this white-colored Factory Line chain lubricant combines solid anti-wear additives (AW/EP) with a tacky carrier to deliver long-lasting lubrication, corrosion resistance, and reduced maintenance mess. Its fast-drying formulation penetrates link pins and rollers while the sticky top layer stays put under rapid acceleration and wet conditions, helping preserve chains and sprockets without harming O-ring, X-ring, or Z-ring seals.

How does this lube behave at race or high speed?

Motul MC Care C4 uses a very adhesive matrix that adheres to chain surfaces to limit fling and maintain a protective film during high-speed riding. The formulation balances penetration with a tacky surface layer so the lubricant remains effective even after extended runs.

• Factory Line sticky formula minimizes fling-off at high RPMs
• Penetrates rollers and pins for internal protection
• Maintains lubrication under high load and centrifugal forces

Will it harm my O-ring, X-ring or Z-ring chain seals?

This aerosol is formulated to be compatible with modern sealed chains and will not degrade common elastomer seals when used as directed. It preserves chain seal integrity while delivering lubrication and protection to internal components of the chain assembly.

• Safe for O-ring, X-ring and Z-ring chains
• Non-aggressive solvent system protects rubber seals
• Reduces seal swelling and premature failure risks when applied properly

What level of wear and corrosion protection does it provide?

Containing AW (anti-wear) and EP (extreme pressure) solid additives, the C4 spray forms a protective layer that resists friction, moisture and road contaminants. That combination helps reduce metal-to-metal wear and slows corrosion, extending the service life of chains and sprockets under demanding conditions.

• AW/EP solid additives for reduced friction and wear
• Corrosion inhibition against water and salt spray
• Protective film that repels grime and contaminants

How easy is it to apply and maintain between rides?

The product comes in a precision aerosol can with a targeted spray pattern for quick, low-mess application. It dries quickly to a tacky film, so routine maintenance is faster and cleaner—ideal for frequent track sessions or regular street upkeep.

• 9 oz aerosol for precise, controlled sprays
• Fast-drying formula reduces dripping and overspray cleanup
• Recommended application frequency: inspect and reapply based on riding conditions

Who is this for? Motul MC Care C4 Chain Lube Factory Line is best suited for sportbike riders, racers, and performance-minded enthusiasts who need a resilient, high-adhesion chain lubricant that performs under high speeds and harsh conditions. If you ride aggressively, compete, or simply want a professional-grade product that protects sealed chains while minimizing fling and maintenance time, this lubricant offers a balance of penetration, anti-wear chemistry, and tacky surface protection. For casual riders or those seeking a non-tacky, almost dry wax finish, consider alternatives tailored to low-fling dry-film lubricants.
