AMSOIL INC., the premier manufacturer of synthetic motorcycle
lubricants, focuses on improving lubricant performance so riders can
focus on improving their performance on the trail or track. That's why
AMSOIL is the Official Oil of AMSOIL GNCC and the choice of professional riders and weekend warriors everywhere.
Delivers Confidence in 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 AMSOIL-sponsored professional riders on the GEICO/AMSOIL/Honda Factory Connection and Team Babbitt's racing teams. A combination of racer feedback and lab testing allowed AMSOIL to fine-tune AMSOIL Synthetic Dirt Bike Oil for outstanding wear protection and consistent clutch feel – benefits riders demand.
