Motul MC Care C4 Factory Line Chain Lube — 9.3 oz White, High-Adhesion, O‑Ring Safe

Motul MC Care C4 Chain Lube Factory Line is a racing-grade aerosol chain lubricant that clings at high speed, protects O‑ring seals, and resists wear and corrosion.

Designed for spirited road riding and track use, this white, fast-drying spray delivers a high-adhesion protective film developed from performance additives and extreme pressure chemistry. It penetrates rollers and link plates while remaining safe for O‑ring, X‑ring and Z‑ring chains, helping reduce friction, water ingress and rust without excessive fling-off. The precision nozzle lets you coat the chain quickly with controlled flow, so maintenance is faster and cleaner.

How does this lube perform at high speeds?

Motul's sticky Factory Line formula minimizes fling and keeps lubrication where it's needed even under sustained high RPMs. That means less mess on the swingarm and more consistent protection during aggressive riding.

• High-adhesion polymeric additives reduce fling-off at speed.
• Creates a durable film that resists centrifugal shedding.
• Specifically tuned for racing stresses and rapid chain movement.

Is it safe for O-ring and sealed chains?

Yes — the MC Care C4 spray is formulated to be compatible with O‑ring, X‑ring and Z‑ring seals, using chemistry that avoids swelling or degrading elastomeric components. It maintains seal integrity while lubricating internal surfaces.

• Seal-safe formula preserves O‑ring elasticity.
• Pennetrates between seals to lubricate rollers and pins.
• Suitable for both new and serviceable sealed chains.

What protection does it offer against wear and corrosion?

This lubricant combines extreme-pressure (EP) additives with corrosion inhibitors to cut friction and shield metal surfaces from moisture and contaminants. Regular application helps extend the life of chains and sprockets under wet or dusty conditions.

• EP additives reduce metal-to-metal contact and wear.
• Anti-corrosion agents resist rust in wet environments.
• White film makes coverage inspection easier after application.

How easy is it to apply and maintain?

The aerosol format and precision nozzle make targeted application fast and tidy, ideal for frequent maintenance between rides or after track sessions. It dries quickly to a tacky finish, so you can ride almost immediately with minimal sling.

• 9.3 oz spray can with controlled spray pattern for even coats.
• Fast-drying formula reduces downtime after servicing.
• White residue helps you visually confirm complete coverage.

Who is this for? Riders who demand a racing-capable chain lubricant that balances aggressive adhesion with seal compatibility will benefit most — sportbike racers, track-day enthusiasts, and anyone who wants long-lasting wear and corrosion protection without frequent reapplication. If you need a professional-grade spray that performs at high speed, clings through hard use, and is safe for sealed chains, Motul MC Care C4 is engineered for that role.
