Wet Clutch Compatible JASO MA2 Certified for Confident, Smooth Shifting: Certified to JASO MA2 (2023, M033MOT210), this 20w50 oil delivers the friction coefficient wet clutch systems require to engage cleanly and shift without slippage. Riders of air-cooled V-twin engines, big singles, and classic twins consistently report noticeably smoother gear changes and reduced transmission noise. The Ester-reinforced oil film maintains its grip under the high shear loads of integrated engine-gearbox-clutch designs
High-Temperature Stability for Air-Cooled and Big Bore Engines: High-Temperature Stability for Air-Cooled and Big Bore Engines: Formulated with a 242 C flash point and 18.0 mm2/s kinematic viscosity at 100 C, this 20w-50 motorcycle oil holds its protective film at operating temperatures where thinner oils break down. The Grade 50 viscosity is purpose-built for the sustained thermal loads of large-displacement air-cooled engines running in stop-and-go traffic, hot climates, and extended summer rides. Viscosity index of 132 confirms consistent performance across a wide temperature range
Technosynthese Ester Technology Semi-Synthetic Performance Beyond Conventional Blends: Motul 5100 uses a proprietary Technosynthese base stock reinforced with Ester molecules that bond to metal surfaces and maintain lubrication even during cold starts and oil-starved moments. This 20 50 synthetic motorcycle oil provides measurably better anti-wear protection than conventional mineral or standard synthetic blend formulations. Density of 0.876 g/cm3 and pour point of -27 C confirm a precisely engineered lubricant, not a relabeled automotive product
Broad Motorcycle and Powersport Compatibility Harley, Cruiser, Classic, Off-Road: Engineered for 4-stroke motorcycles, ATVs, UTVs, and side-by-sides that specify SAE 20W-50 viscosity. Fits Harley-Davidson Sportster, Dyna, Softail, and Street Bob models as well as Triumph Bonneville, Royal Enfield Classic and Bullet, Moto Guzzi V7/V9, and BMW air-cooled Boxers. Also serves Suzuki DR-Z thumpers and Kawasaki Vulcan cruisers. Meets API SP for modern emissions compliance including catalytic converter compatibility
Oxidation-Resistant Formula Drain Intervals Up to 16,000 km: This v-twin motorcycle motor oil resists oxidation and deposit formation across extended service intervals, keeping engines cleaner between changes. Formulated for drain intervals of up to 16,000 km depending on manufacturer recommendations, reducing maintenance frequency and cost for daily commuters and weekend riders. The 20w50 synthetic oil base stock maintains its protective properties longer than conventional mineral oils under repeated thermal cycling, meaning fewer oil changes per riding season without compromising engine cleanliness
