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 V-Twin Motorcycle Oil contains special anti-rust agents providing outstanding protection against rust and corrosion.

Catalytic-Converter Compatible
AMSOIL Synthetic V-Twin Motorcycle Oil meets the requirements for emission-system protection and is designed for use in motorcycles with catalytic converters.

Provides Excellent Wet-Clutch Performance
AMSOIL Synthetic V-Twin Motorcycle Oil delivers the confidence of quiet smooth shifting and positive clutch engagement. It controls heat and helps prevent slippage and glazing.
