AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives.

Controls Foam
High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit.

Delivers Superior Rust and Corrosion protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.

Metric Motorcycle Oil Customer Comments:
Metric Motorcycle Synthetic
By JIM, a Verified Buyer on July 10, 2025
I bought a new 2007 gold wing. After a few years I switched from Honda oil to Amsoil Metric synthetic and noticed better and smoother shifting on first oil change. Never looked back. Should have done it sooner.
Great oil
By JOSEPH, a Verified Buyer on July 09, 2025
Put Amsoil into my BMW R9t and never ran better!
The best oil for my motorbike.
By GILLES, a Verified Buyer from Port-Cartier, QC. Canada on June 30, 2025
My ride, a Yamaha Venture Trans-Continental (1900) is running smoothly with this oil, the engine and the transmission. I used this kind of oil before, on Kawasaki Concours 14 and on Yamaha Roadliner. It’s a very good oil and you may do a lot of kilometers ( more than the norm) with the same oil without any hassle. When the best product is available….you use it!!
Best oil for Powersports
By MATTHEW, a Verified Buyer on May 20, 2025
I use this oil in all my Sportbikes and dirtbikes and have for 14 years. I wouldn’t dream of using anything else in them. The motors run quiet the clutch performance flawless. No slipping when I change the oil there’s no sediment in the oil from the clutch pads like you will see with other oils. This oil doesn’t foam up like other oils do in the high rpm engines. The oil stays where the work is being done and keeps the parts lubricated throughout its lifecycle.
Better than previous oil used
By grnblur, a Verified Buyer from SC on May 19, 2025
I have been using Castrol Syntech for decades on all my motorcycles prior to them changing formulation. Since the cost of oils have gone up and Amsoil stays close to the same I gave it a try 4 oil changes ago on my street bike. It lasts longer than the previous oil is the fact that on a Concours 14 the transmission gets harder to shift when the oil starts breaking down. This oil lasts about 1500 miles longer before the transmission gets notchy.
Amsoil 10/30 metric works great
