WD-40 Specialist Motorcycle Chain Wax is a high-performance power-spray lubricant for use exclusively on chain-driven vehicles. Its special Parafilm???formula provides long-term coverage for all chain surfaces, leaving a waxy film appearance. This heavy-duty, water-displacing film provides protection especially in water and high-humidity environments. Chain Wax is formulated with anti-wear and extreme-pressure additives that provide high-performance lubrication for all chains. Chain Wax penetrates deeply, lubricating non-accessible areas, reducing chain stretch and chain wear. Contains no silicone.
