Hot Rods 85-87 Kawasaki KX 125 125cc Main Bearing & Seal Kit

These Hot Rods main bearings are C3 rated for high-speed operation, meaning they have a bit more internal clearance than standard bearings. This extra room helps them handle the heat and stress that comes with running a 125cc two-stroke engine hard, especially in off-road applications like your Kawasaki KX 125. They're built to meet or exceed the original equipment manufacturer's specifications, offering a solid, cost-effective way to rebuild or refresh your engine's bottom end.

When you're rebuilding the crankcase, replacing the main bearings is a critical step. These kits include the necessary bearings and seals to get the job done right. They're a well-built alternative to OEM parts, giving you the confidence that your engine's rotating assembly will be supported properly. Proper bearing installation is key to a long-lasting engine, so make sure to follow the manufacturer's recommended procedures.
