Restore top-end performance with the Namura NX-10080-BK1 Top End Kit for select Honda CR80R models. This kit is designed for motorcycles equipped with a Nikasil-plated cylinder and includes the piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit needed for a complete top-end service. The 46.95 mm piston size is engineered for proper fitment in compatible Honda CR80R applications.
The Namura piston uses a hypereutectic casting process that increases silicon content to help reduce expansion, improve wear resistance, and withstand elevated cylinder temperatures. MOS2, or Teflon/molybdenum, coated skirts are applied using a rolled-on process that creates a durable bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. The machined smooth piston head helps reflect combustion heat and reduce carbon buildup, supporting consistent performance and piston protection.
An anodized piston dome provides increased heat resistance and durability compared with non-anodized designs. The included components make this kit a practical choice for rebuilding the top end of a compatible Honda two-stroke engine. Verify cylinder condition, bore size, and model-year compatibility before installation. This Namura kit fits the 1992–2002 Honda CR80R, including 1992, 1993, 1994, 1996, 1997, 1998, 1999, 2000, 2001, and 2002 models.
