Dirt Bike

AMSOIL Synthetic Dirt Bike Oil goes beyond protecting dirt bike engines and transmissions… it improves rider’s performance. Formulated to avoid clutch slip, fade and chatter, it delivers a consistent clutch feel… unique to competition riders and enthusiast alike. AMSOIL synthetic base oil technology naturally resist viscosity loss (caused by extreme heat) providing a constant protective film to protect gears, bearings and pistons to help riders push their bikes to the limit!
Our customers have asked: “I have always used AMSOIL Synthetic Motorcycle Oil in my dirt bike with good results. Is there any reason to switch to Synthetic Dirt Bike Oil?”
Amsoil Technical: “Although AMSOIL Synthetic Motorcycle Oil is perfectly suitable for dirt bikes, AMSOIL Synthetic Dirt Bike Oil is formulated specifically to meet the unique demands of four-stroke dirt bikes. For example, the clutch feel and protection are dialed in for dirt bike riders, while AMSOIL Synthetic Motorcycle Oil is formulated more to the needs of on-road motorcycles.”
The AMSOIL difference is a lubricant formulated specifically for wet clutches. Lubricating a clutch with oil seems like an invitation for slippage and inconsistent shifting. However, a properly formulated oil can reduce clutch slippage. AMSOIL Synthetic V-Twin Motorcycle Oil, Synthetic Metric Motorcycle Oil, Synthetic Dirt Bike Oil and Synthetic Dirt Bike Transmission Fluid contain no friction modifiers or extreme-pressure additives. Instead, each product is dialed-in with the correct frictional properties to promote smooth shifts and consistent clutch feel while guarding against wear for longer clutch life.
