AMSOIL 100% Synthetic SAE 15W-50 4T Performance Motorcycle Oil (946 ml / 1 U.S. Quart) is a premium, high-viscosity lubricant engineered to provide ultimate shear stability and wear protection for high-performance motorcycles operating under extreme heat and heavy loads. Featuring a robust 100% full-synthetic formulation, it forms a resilient protective film that lowers engine operating temperatures, shields transmission gears, and prevents wet-clutch slippage. Certified to meet rigid JASO MA/MA2 and API SN specifications, this advanced oil actively prevents deposit buildup, controls oil consumption, and delivers exceptionally smooth gear transitions in high-displacement sport bikes, cruisers, and adventure motorcycles.
