Upgrade the top end of your 1998 Suzuki RM250 with the Namura NX-30024-BK Top End Kit. Designed for reliable replacement performance, this kit is intended for models equipped with a SCEM composite cylinder and includes the essential components needed to refresh the piston assembly and top-end sealing surfaces. The kit fits the 1998 Suzuki RM250 and is manufactured by Namura under manufacturer and vendor part number NX-30024-BK.
The Namura piston uses a MOS2, or Teflon and molybdenum, coated skirt applied through a rolled-on process for a durable bond. This coating helps reduce friction, improve heat transfer, and minimize the risk of cold seizures. The machined smooth head reflects combustion heat and helps reduce carbon buildup, supporting piston protection and consistent engine operation. The anodized dome improves heat resistance and durability, while the hypereutectic casting process increases silicon content for controlled expansion, added wear resistance, and improved performance under elevated cylinder temperatures.
The 66.36 mm piston size and included components make this kit a practical solution for rebuilding the top end of the specified Suzuki two-stroke motocross motorcycle. Verify the cylinder condition, piston clearance, and application details before installation to ensure proper fit and service life.
