All Ceramic Bearing kits are built to order and will take one to four days to produce and are non-returnable. Please contact us if a manufacturer defect is present.

How do you get that Factory-Race bike advantage?

One of the secrets is ceramic bearings that are used in nearly every AMA superbike- World Superbike- MotoGP- and Professional Drag Race Motors around the world! Less Weight- less friction and less surface wear equals more horsepower in your motor- simple as that.

Reduced Rotating Mass

The ceramic balls in these hybrid bearings are over 60% lighter than their steel counterparts resulting in faster acceleration and reduced inertial loads.

Low Friction - Less Vibration

The coefficient of friction for the ceramic balls is an average of 3x's lower than steel. When you combine this with the high tolerances for roundness you get a bearing that dramatically lowers vibration levels and produces more horsepower.

Preservation

Due to the unique properties of the ceramic balls these bearings have vastly reduced surface wear when compared to steel balls. The reduction in wear eliminates a large portion of the oil contaminates- thus prolonging lubricant life.

Note: All bearings are custom built and have 2-3 days lead time before shipping.
