What is the difference between standard and undersize conrod bearings?

Standard size bearings are designed to fit a crankshaft that is still within its original factory tolerances. If a crankshaft has been machined undersize due to wear or damage, you would need to use undersize bearings to maintain the correct oil clearance.

Do these bearings come with new bolts?

This product is a set of conrod bearings only. It does not include new connecting rod bolts. You will need to source those separately if required for your engine rebuild.

How do I know if I need standard size bearings?

You should measure your crankshaft journals. If they are within the manufacturer's specified tolerances and have not been machined undersize, then standard size bearings are appropriate. Always refer to your service manual for exact specifications.

Product Details

ACL is a well-known name in engine bearings, and this set is made to the original equipment specifications for your 2000-2005 ZX1200 Ninja ZX-12R. They are standard size, meaning they are designed to fit a crankshaft that is still within its original factory tolerances. If your crankshaft has been machined undersize due to wear or damage, you would need a different size bearing. These are a solid option if you're rebuilding your engine and need to replace worn bearings.

When you're rebuilding an engine, it's important to get all the measurements right. Make sure to check your crankshaft for straightness and measure the journals to confirm they are within spec and haven't been machined undersize. If they have, you'll need to order the corresponding undersize bearings from ACL.
