Consistent Clutch Feel
The superior friction-durability properties of AMSOIL Synthetic Dirt Bike Oil help eliminate clutch slippage, fade and chatter to provide consistent clutch feel during launches and when maneuvering over and around obstacles. In extreme testing, AMSOIL Synthetic Dirt Bike Oil continued to deliver consistent clutch engagement following 32 simulated race starts, while a leading motorcycle manufacturer-branded (OEM) oil demonstrated inconsistent clutch-lever action and poor clutch engagement after only 16 starts. The clutch plates lubricated with AMSOIL Synthetic Dirt Bike Oil remained clean and in good condition, while the plates using the OEM oil revealed discoloration and wear. AMSOIL Synthetic Dirt Bike Oil delivers superior clutch performance, giving riders confidence that their bikes will deliver predictable power when they need it most.
Protects Against Wear
The synthetic base oils in AMSOIL Synthetic Dirt Bike Oil naturally resist mechanical shear and viscosity loss, maintaining a thick protective film that helps prevent metal-to-metal contact under high-rpm operation and extreme heat. Its premium anti-wear additives provide an extra measure of protection against gear, bearing and piston wear that helps reduce maintenance and extend clutch and engine life.
RACING IS RESEARCH™
AMSOIL Synthetic Dirt Bike Oil was extensively performance tested by professional riders in their race bikes. A combination of racer feedback and lab testing was used to fine-tune the formula to deliver maximum anti-wear protection and consistent clutch feel – key benefits that dirt bike riders demand.
APPLICATIONS

SERVICE LIFE
AMSOIL Synthetic Dirt Bike Oil should be changed according to the vehicle manufacturer’s recommendations.
COMPATIBILITY
AMSOIL Synthetic Dirt Bike Oil is compatible with other synthetic and conventional motor oils. However, adding other oils will shorten the life expectancy of AMSOIL motor oils and reduce their performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL Synthetic Dirt Bike Oil.
