Namura NX-30024K2 Top End Kit for 2001–2002 Suzuki RM250

Refresh the top end of your 2001 or 2002 Suzuki RM250 with the Namura NX-30024K2 Top End Kit. Designed for reliable fitment with the original SCEM-composite cylinder, this kit includes the essential components needed for a complete piston replacement and top-end service. It includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit.

The piston uses Namura’s MOS2, or Teflon/molybdenum, coated skirts. This rolled-on coating process creates a bond claimed to be 10 times stronger than many spray-on coatings, helping improve heat transfer, reduce friction, and minimize the risk of cold seizures. The machined smooth head reflects combustion heat and helps reduce carbon buildup, supporting piston protection, performance, and fuel efficiency.

An anodized dome enhances heat resistance and durability, while the hypereutectic casting process provides increased silicon content for controlled expansion, improved wear resistance, and the ability to withstand higher cylinder temperatures. The kit is manufactured for standard-bore service using a 66.35 mm piston, equivalent to approximately 2.612 inches, and is intended for direct fitment on the specified Suzuki RM250 applications.

Choose the Namura NX-30024K2 when replacing worn top-end components on a compatible Suzuki RM250. Verify model year, cylinder condition, and required piston clearance before installation. The manufacturer part number is NX-30024K2, and the vendor part number is 185-30242.
