What does 'extra oil clearance' mean for my engine?

Extra oil clearance means there is a slightly larger gap between the bearing and the crankshaft journal. This allows for more oil to flow through, which can help with cooling and lubrication, especially under high-performance or demanding riding conditions.

Do these bearings come with new bolts?

This set includes the conrod bearings only. New connecting rod bolts are typically recommended or required when replacing bearings, and are sold separately.

Can I use these if my crankshaft has been machined?

These bearings are standard size and designed for a factory-spec crankshaft. If your crankshaft has been machined undersize due to wear or for performance modifications, you will need to use a set of undersize bearings instead.

Product Details

ACL has designed these bearings with extra oil clearance. This means there's a bit more room for oil to flow around the crankshaft journal, which can help keep things cooler and better lubricated, especially under demanding conditions. They are made to the standard size, so they're a direct replacement for your original bearings if the crankshaft is still within factory specifications. Proper bearing clearance is crucial for engine longevity and performance.

When you're rebuilding or refreshing the bottom end of your Ninja ZX-12R, getting the right bearings is key. Make sure to check your crankshaft journals for any wear or damage before installing these bearings, as they are designed for standard-sized cranks. If your crank has been machined undersize, you'll need a different set of bearings.
