What Every Rider Should Know
The tradition of innovation and technological advancement continues with AMSOIL synthetic lubricants for dirt bikes. Hours of testing in AMSOIL chemical and mechanical labs resulted in lubricants engineered to maximize your bike’s performance on the trail and at the track. Testing with professional teams in Monster Energy Supercross, AMSOIL Arenacross and AMSOIL GNCC helped further fine-tune AMSOIL Synthetic Dirt Bike Oil for outstanding wear protection and consistent clutch feel. AMSOIL Synthetic Dirt Bike Oil delivers the confidence and performance you need to get on it and get out front.
Maximum Horsepower
AMSOIL Synthetic Dirt Bike Oil is formulated to maximize horsepower. It uses synthetic base oils to reduce energy lost to friction, allowing your engine to work less to deliver more power to the ground.
Consistent Clutch Feel
Clutch slippage or inconsistent clutch feel can prevent dirt bike riders from riding as fast or effectively as they like. To keep the engine within the power band, riders often modulate the clutch, increasing the opportunity for clutch slippage if low-quality lubricants are used.
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.
Superior Wear Protection
High-revving dirt bikes can tear apart the molecular structure of motor oil, resulting in viscosity loss. Most four-stroke bikes use a shared sump that supplies oil for the motor, transmission and primary chaincase. Transmission gears can cause shear-induced viscosity loss if inferior oils are used. Oil that has lost viscosity can fail to develop a strong lubricating film on metal components, leading to wear. AMSOIL Synthetic Dirt Bike Oil’s durable synthetic base oils naturally resist viscosity loss due to mechanical shear.
By retaining its viscosity despite high heat and shearing forces, AMSOIL Synthetic Dirt Bike Oil guards against gear wear for maximum component life, helping riders get the most out of their bikes.
