Synthetic Dirt Bike Oil
AMSOIL
Delivers Confident Clutch Feel
AMSOIL Synthetic Dirt Bike Oil’s superior friction-durability properties help minimize clutch
slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when
maneuvering around obstacles on the trail. In an extreme simulated-start test,
AMSOIL Synthetic Dirt Bike Oil 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 Synthetic Dirt Bike Oil remained clean and in good overall
condition, while the plates using the OEM oil revealed discoloration and wear. AMSOIL Synthetic
Dirt Bike Oil’s superior performance helps instill in riders the confidence that their bikes will
perform consistently in all types of riding conditions.
Protects Against Wear
AMSOIL Synthetic Dirt Bike Oil withstands high-rpm operation, extreme heat and mechanical shear.
Its synthetic base oils naturally resist viscosity loss and provide a protective film against wear
to gears, bearings and pistons. Its anti-wear additives provide an extra measure of protection,
promoting long component life to help riders
get the most out of their bikes.
RACING IS RESEARCH
AMSOIL Synthetic Dirt Bike Oil underwent extensive on-track testing in the bikes of professional
riders. A combination of racer feedback and lab testing allowed us to fine-tune AMSOIL Synthetic
Dirt Bike Oil for outstanding wear protection and
consistent clutch feel – benefits riders demand.
