Bel-Ray EXP Synthetic 15W-50 Motorcycle Oil
Engineered for peak performance in 4-stroke motorcycles, this synthetic ester-blend oil delivers unmatched protection across extreme temperatures and riding conditions. Designed to maintain optimal viscosity during high-stress operations—whether navigating desert trails or city commutes—it safeguards engine components while enhancing power delivery.
Key Advantages
✅ Dual-Cooling Compatibility: Seamlessly integrates with air-cooled vintage bikes and liquid-cooled modern sportbikes
✅ Clutch-Safe Formula: JASO MA2 certification ensures smooth gear engagement without compromising wet clutch durability
✅ Metal-Protective Technology: Advanced anti-wear additives form a microscopic shield on piston rings and cylinder walls
✅ Heat Resistance: Shear-stable viscosity index (VI) improvers maintain 15W-50 consistency through 200+ hours of operation
Ideal for:
– Endurance racers requiring 500+ mile drain intervals
– Adventure riders facing -30°C to 120°C temperature swings
– Café racers seeking 2-3% horsepower gains over conventional oils
