AMSOIL Synthetic Dirt Bike Motorcycle Oil

AMSOIL Synthetic Dirt Bike Motorcycle Oil is engineered for the severe operating conditions encountered in motocross, enduro, trail and other off-road motorcycle applications. High engine speeds, repeated acceleration, elevated temperatures and demanding clutch and transmission use can place exceptional stress on the lubricant.

Built for Demanding Off-Road Riding

Off-road motorcycles can experience rapid changes in engine load and speed while operating in environments where heat, dust and demanding terrain add to the challenge. In many four-stroke dirt bikes, the lubricant must also protect transmission gears and provide appropriate performance for a heavily used wet clutch.

AMSOIL Dirt Bike Synthetic Motorcycle Oil is formulated to provide strong wear protection, resist viscosity loss and maintain dependable lubrication under the severe mechanical and thermal conditions encountered during off-road riding and competition.

Clutch and Transmission Performance

Frequent gear changes and clutch operation are fundamental to motocross, enduro and technical trail riding. Where the engine, transmission and clutch share a lubricant, the oil must withstand transmission shear while maintaining friction characteristics appropriate for wet-clutch operation.

Our JASO Motorcycle Oil Standards Guide explains the MA and MA2 classifications commonly encountered when selecting oil for four-stroke motorcycles with wet clutches.
