What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining precise oil clearance, which is essential for reducing friction and wear.

What does 'STD' size mean for these bearings?

STD stands for standard size. These bearings are meant to be used when the crankshaft and the main bearing journals are within the manufacturer's specified standard dimensions, without any machining or grinding.

Are these bearings sold individually or as a set?

This product is a set of main bearings, specifically intended for the #1, #3, and #5 positions of the engine. It is not a complete set for all main bearing positions.

About this part

Product Details

If you're rebuilding the engine on your Kawasaki ZX-14R from 2012 and newer, getting the main bearings right is crucial for smooth operation and longevity. This set from King Engine Bearings is designed to fit the #1, #3, and #5 main bearing positions, using standard (STD) size bearings.

King Engine Bearings is a well-known name in engine components, and these bearings are built to handle the demands of a high-performance motorcycle engine. They are made with materials chosen for their ability to withstand the pressures and temperatures found within the crankcase, helping to maintain proper oil clearance and reduce friction. Getting the correct size and fitment for these critical components ensures the crankshaft spins freely and reliably.
