AMSOIL's exclusive advanced chemistry provides outstanding engine reliability for worry-free operation under severe conditions.   AMSOIL  is the choice of professional off-road motorcycle racers, motocross racers, and weekend dirt bike riders everywhere. When you demand the best for your dirt bike, always use the best dirt bike oil, choose AMSOIL.

AMSOIL Delivers Confident Clutch Feel

AMSOIL Synthetic Oil For Dirt Bikes features superior friction-durability properties to help minimize clutch slippage, fade, and chatter, giving riders a consistent clutch feel during takeoffs or when maneuvering around obstacles on the trail. In an extreme simulated-start test, AMSOIL continued to deliver consistent clutch feel following 32 simulated race starts, while a leading original equipment manufacturer (OEM)-branded oil demonstrated inconsistent clutch-lever action and poor clutch feel after 16 starts. The clutch plates lubricated with AMSOIL remained clean and in good overall condition, while the plates using the OEM oil revealed discoloration and wear. AMSOIL's superior performance helps instill in riders the confidence that their bikes will perform consistently in all types of riding conditions.

Its anti-wear additives provide an extra measure of protection, promoting long component life to help riders get the most out of their bikes.
