AMSOIL Motorcycle Street & Race Synthetic Oil
AMSOIL Motorcycle Street & Race Synthetic Motorcycle Oil is engineered for high-performance street and racing motorcycles where exceptional engine protection, transmission performance and consistent clutch operation are critical. Its advanced synthetic formulation is designed for the high temperatures, high engine speeds and severe mechanical stresses encountered in demanding motorcycle applications.
Engine, Transmission and Clutch Protection
In motorcycles using a shared lubricant system, the oil may be responsible for protecting the engine while simultaneously lubricating transmission gears and operating with a wet clutch. These combined demands require more than simply selecting an automotive engine oil with the correct viscosity.
Motorcycle Street & Race Synthetic Oil is formulated to resist viscosity loss under mechanical shear while providing the friction characteristics required for appropriate wet-clutch performance. This helps support smooth shifting and consistent clutch operation alongside protection of critical engine components.
Built for High-Performance Motorcycles
High-performance motorcycle engines can expose lubricants to elevated temperatures and extreme engine speeds, while aggressive riding and competition use increase the demands placed on engines, transmissions and clutches. Motorcycle Street & Race is AMSOIL's premium synthetic range for riders seeking high levels of protection and performance in these applications.
JASO and Wet-Clutch Performance
JASO motorcycle oil classifications help identify oils with friction characteristics appropriate for different motorcycle lubrication systems. Our JASO Motorcycle Oil Standards Guide explains MA, MA1, MA2 and MB and why these classifications matter when an engine, transmission and wet clutch share the same lubricant.
