Synthetic Wear Protection

AMSOIL SAE 60 Motorcycle Oil’s synthetic formula is loaded with anti-wear features designed to protect hot-running engines and transmissions. This synthetic SAE 60 will not thin or break down in extreme heat, so your investment is protected all season long. In the charts below, see how AMSOIL Synthetic SAE 60 Motorcycle Oil compares versus Harley-Davidson HD-360 SAE 60 Motorcycle Oil. AMSOIL provides better wear protection in the 4-Ball Wear test (first chart) and it also resists shearing under hot temperature testing in the High Temperature/High Shear test (second chart).

Steady Heat Resistance

The biggest issue with big bore, air-cooled motorcycle engines is heat. Idling and slow cruising on hot days and can really generate heat. AMSOIL Synthetic SAE 60 Motorcycle Oil’s low friction formula keeps temperatures at bay. The synthetic formula will not shear down or boil off, so you get reliable engine and transmission performance and protection on the hottest days imaginable and oil consumption is greatly reduced.

No-Compromise Protection for Harley Transmissions

You can confidently use AMSOIL Synthetic SAE 60 Motorcycle Oil in the transmission as well as the engine. Powerful anti-wear additives protects gears and bearings. This oil is a no-compromise replacement for SAE 140 gear lube. AMSOIL SAE 60 is 100% wet-clutch compatible. The myth that synthetic oil causes motorcycle clutch slippage stems from people mistakenly using automotive motor oil in their bikes. Car engine oil contains friction modifiers which causes clutch plate glazing. The cooler operation provides by this SAE 60 Motorcycle Oil can actually extend clutch plate life. We have written extensively on this subject. Check out Does Synthetic Motorcycle Oil Cause Wet Clutch Problems?

Storage Corrosion Protection

The world-class protection offered by AMSOIL Synthetic SAE 60 Motorcycle Oil doesn’t stop when you park your bike in the fall. AMSOIL SAE 60 contains special additives that provide unparalleled anti-rust and corrosion defense so that engine and transmission internals are protected during long storage periods.
