Purpose and Specifications

Castrol Power 1 Racing 4T 5W-40 is a fully synthetic engine oil designed for high-performance 4-stroke motorcycles. It boosts engine acceleration and power up to maximum RPM, thanks to its Race Derived Technology that reduces friction for smoother, faster rides. The 5W-40 viscosity flows easily in cold starts down to -30°C and stays thick under extreme heat above 150°C, protecting air-cooled and water-cooled engines during hard riding. With Trizone Technology, it safeguards the engine, clutch, and gears under tough conditions like sustained high speeds. Meets API SJ/MA-2 specs, approved for BMW models like S1000RR and K1600, and works in wet clutch systems for precise shifting.

When to Use / Replace?

Use this oil in modern sports bikes for track days, aggressive street riding, or daily high-rev use where API and JASO MA-2 are required. Replace every 5,000-8,000 km or 6-12 months, whichever comes first, to maintain peak performance and prevent wear. Store sealed bottles in a cool, dry place below 60°C; shelf life is 3-5 years unopened.
