What does '+0.25mm' mean for these bearings?

The '+0.25mm' indicates that these bearings are designed for a crankshaft that has been machined down by 0.25mm. This is a common practice when a crankshaft has worn beyond its original specifications or to achieve a specific bearing clearance during an engine rebuild.

What is the XP series from King Engine Bearings?

The XP series from King Engine Bearings utilizes a specialized overlay material. This overlay is known for its toughness and ability to resist wear, making these bearings a solid option for performance engines where durability under stress is important.

Are these bearings a direct replacement for stock?

These bearings are a direct replacement in terms of fitment for the specified Kawasaki ZX-14 models, but they are an undersize part (+0.25mm). This means they are intended for use with a crankshaft that has been machined to match this size, not for a stock, unmachined crankshaft.
