Advanced Synthetic Technology
Reduces Friction, Heat and Wear
AMSOIL Synthetic Metric Motorcycle Oil is thermally stable at high temperatures and exceeds industry standards for high-temperature film strength to reduce friction and keep engines and transmissions running cool. Its optimized antioxidant additives are engineered to prevent damaging sludge and carbon deposit formation for superior engine cleanliness and improved performance.
AMSOIL Synthetic Metric Motorcycle Oil also contains premium anti-wear additives that help reduce engine wear under any operating conditions.
Smooth, Confident Shifts
AMSOIL Synthetic Metric Motorcycle Oil is engineered to control heat and eliminate glazing for positive clutch engagement and longer clutch life. It contains no friction modifiers, which prevents slippage for smoother, more confident shifts.
The oil meets JASO MA/MA2 specifications, ensuring compatibility with wet clutch systems found in most metric motorcycles.
Controls Foam
High-rpm operation causes some motor oils to foam. Foam bubbles collapse when traveling between gear teeth and engine components, allowing metal surfaces to contact and cause wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, so riders can confidently push their bikes to the limit.
Delivers Superior Rust and Corrosion Protection
Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-corrosion agents that deliver superior protection during storage and long periods of inactivity. With its high 11.6 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection against acid corrosion and rust to help maintain internal engine cleanliness.

AMSOIL Synthetic Metric Motorcycle Oil provides reserve protection, allowing you to extend drain intervals when conditions permit:
With AMSOIL Oil Filter
- Up to 2X the motorcycle manufacturer-recommended change interval
- Maximum: Miles/hours or one year, whichever comes first
