10W-50 Synthetic Dirt Bike Oil



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 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.

  • Delivers confidence in clutch feel
  • Superior protection against gear, bearing & piston wear
  • Maximizes horsepower
  • Helps extend clutch life

    I run amsoil in all my toys. I don’t mind spending more to get a great product as the old saying goes you get what you pay for. I’m not one to spend a bunch of money on a bike or side by side then cheap out on maintenance, I prefer my stuff to last and that’s why I use amsoil.
