MOTUL 7100 20W50 100% SYN 4-LITER (1041 104104

• 100% Synthetic Ester Formula — Reinforced Engine Protection: 100% synthetic motor oil built on ester technology, the same molecular base used in Motul 300V competition-grade lubricants, providing reinforced film strength and shear resistance at high operating temperatures. Ester molecules form a persistent bond with metal surfaces, maintaining a stable protective layer under the thermal stress of air-cooled, high-displacement V-twin engines. API SP certified additive package delivers advanced wear protection, oxidation resistance, and deposit control throughout the full drain interval
• JASO MA2 Certified — Precise Wet Clutch Engagement and Gear Response: JASO MA2 (T903:2023) certified for optimized wet clutch performance, delivering sharp and consistent gear engagement across the entire operating temperature range. The ester-based formulation enhances friction-surface adhesion for responsive throttle feedback and reduced drivetrain vibration in motorcycles with integrated engine-gearbox-clutch systems. Formulated to maintain stable friction coefficients that ensure predictable clutch feel whether cold-starting or at sustained operating temperature
• Engineered for Air-Cooled, High-Temperature V-Twin Operation: Specifically formulated to maintain viscosity stability and film integrity under the extreme thermal demands of air-cooled, high-displacement engines operating at sustained highway speeds and elevated ambient temperatures. The synthetic ester base resists thermal breakdown and viscosity loss at operating temperatures where standard formulations degrade, ensuring consistent lubrication across all riding conditions. Recommended for Harley-Davidson Milwaukee-Eight, Twin Cam 88/96/103/110, Evolution 1340, and Sportster 883/1200 powerplants
• Extended Drain Interval Performance — Advanced Oxidation Stability: API SP additive package provides measurable oxidation stability, sludge resistance, and internal engine cleanliness over the full OEM-recommended drain interval. The 100% synthetic ester base maintains protective and detergent properties at the elevated operating temperatures typical of air-cooled motorcycle architectures, reducing deposit formation on critical engine components. Compatible with motorcycles equipped with catalytic converters and exhaust after-treatment systems for emissions-compliant operation
• Application Compatibility — Harley-Davidson, URAL, and SAE 20W-50 V-Twins: Recommended for Harley-Davidson and URAL motorcycles requiring SAE 20W-50 viscosity grade in the engine. The reinforced anti-wear additive package, inspired by 300V motorsport technology, provides the film strength and thermal resilience demanded by high-displacement, air-cooled V-twin powerplants. Available in 1-liter and 4-liter sizes with packaging manufactured from 50% recycled plastic that is 100% recyclable.
