Motorbike 4T 15W-50 Street 1L is a heavy-duty 4-stroke engine oil specifically formulated for large displacement cruisers, V-twins, air-cooled engines, classic motorcycles, and high-mileage bikes. The 15W-50 viscosity provides a thick, robust oil film that excels under extreme heat, heavy loads, and high-stress riding conditions.

Whether you ride a Harley-Davidson Sportster, Royal Enfield Bullet, Honda Shadow, Suzuki Boulevard, Kawasaki Vulcan, or Triumph Bonneville, this oil delivers the reliable protection your engine demands.

• Maximum High-Temperature Protection – Thick 15W-50 film strength prevents metal-to-metal contact in air-cooled V-twins and classic engines.

• Superior Oil Consumption Control – Reduces burn-off in older, high-mileage, or air-cooled engines.

• Air-Cooled Optimized – Formulated to handle the extreme heat generated by air-cooled cylinders and cylinder heads.

• Smooth Wet Clutch Performance – JASO MA/MA2 compliant – reliable shifting with no clutch slippage.

• Excellent Wear Protection – Advanced anti-wear additives protect camshafts (critical on Harleys and Royal Enfields), lifters, rockers, and gearboxes.

• Deposit Control – Keeps piston rings free and reduces sludge, varnish, and carbon deposits common in air-cooled engines.

• Shear Stability – Resists viscosity breakdown in high-stress transmissions and gearboxes.
