What is the main function of these bearings?

These main bearings support the crankshaft within the engine block. They create a smooth surface for the crankshaft to rotate on, while also maintaining precise oil clearance to ensure proper lubrication and reduce friction.

What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are designed to fit crankshaft journals that are still within the original factory specifications, without any machining or grinding.

What is the XP series material?

The XP series from King Engine Bearings uses a specialized tri-metal material. This material is developed to offer better performance and durability compared to standard bearing materials, especially in high-stress engine applications.

Product Details

This is a standard size main bearing set from King Engine Bearings, specifically for the Kawasaki ZX-14R motorcycle, model years 2012 and newer. These bearings are a crucial part of your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the crankcase. When you're rebuilding or refreshing the engine on your ZX-14R, using well-made bearings like these is important for maintaining proper oil clearance and reducing friction.

King Engine Bearings is known for their XP series, which uses a specialized tri-metal material that offers improved performance over standard bearings. This material is designed to handle the stresses of high-performance engines, providing a solid foundation for your crankshaft. This particular set is for the #2 and #4 main bearing positions and is standard size, meaning it's meant to be used when the crankshaft journals are still within their original factory specifications.

For installation, it's always best to refer to the manufacturer's service manual for your specific ZX-14R. Proper cleaning of the crankcase and crankshaft journals is essential before installing new bearings to ensure optimal performance and longevity.
