10W-50 100% Synthetic Motorcycle Oil

Premium Engine and Transmission Lubricant

AMSOIL Synthetic Motorcycle Oil is designed for motorcyclists who demand maximum protection and performance no matter how hard they ride. It is precision engineered to deliver immediate engine response and maximum power and acceleration in high-performance motorcycles. Its 100% synthetic base oils and advanced additive technology ensure longlasting protection against engine and transmission wear for motorcycles operating at extreme temperatures. Its shear-stable formula maintains viscosity under the extreme pressure of wet-clutch transmissions to provide consistently smooth and precise shifting. Advanced detergency helps keep your engine and transmission clean to deliver stable oil pressure, precise control, enhanced reliability and long engine life.

Package sizes include:

  • Quart Bottle
  • Quart Bottle (Case of 12)

Minimizes Friction, Heat and Wear

Modern high-performance motorcycles feature tightly integrated engines that produce extreme heat, especially in stop-and-go traffic, during aggressive riding and on hot summer days. Temperatures that exceed the limit of the oil can threaten its ability to protect your engine and transmission. AMSOIL Synthetic Motorcycle Oil is thermally stable to maintain viscosity in high-heat conditions. It contains advanced oxidation inhibitors that prevent damaging sludge formation to maintain engine cleanliness and help prevent clutch-plate glazing. It retains its lubricating film strength to reduce friction
and heat, keep engines running cool and deliver superior protection against wear.

Delivers Smooth, Precise Shifts

Motorcycle transmissions and clutch plates are often lubricated by the motor oil. The high pressures and mechanical shearing forces of high-rpm operation and gear engagement can physically tear lesser oils apart. AMSOIL Synthetic Motorcycle Oil is shear stable to maintain its viscosity in wet-clutch motorcycles that use the same oil for the engine and transmission. It is formulated without friction modifiers to deliver positive clutch engagement, smooth, precise shifting and long clutch life.

Controls Foam
High-rpm operation and gear shifts introduce air, which causes some oils to foam. As foam travels between gears and engine components the bubbles collapse and form air pockets that increase heat and oxidation and allow contact between metal surfaces. AMSOIL Synthetic Motorcycle Oil contains advanced anti-foam technology that prevents air bubbles from forming, reducing heat and wear and extending oil life.

Prevents Rust and Corrosion

When motorcycles are not ridden regularly, moisture can accumulate inside the engine and cause corrosion. Abrasive rust leaves pits in metal surfaces, rapidly accelerates wear and can cause compression loss, blow-by and even catastrophic engine failure. AMSOIL Synthetic Motorcycle Oil contains advanced rust and corrosion inhibitors that protect your bike from the damaging effects of corrosion in between rides and while it is in storage.
