Restore top-end performance with the Namura NX-30085-CK Top End Kit, designed for select Suzuki RM85 two-stroke motorcycles. This complete kit includes a piston, piston rings, wrist pin, retaining clips, top-end bearing, and gasket kit for a convenient engine refresh. The kit is intended for Suzuki RM85 models from 2002-2009 and 2020, providing replacement components for compatible standard or specified cylinder applications.
The piston uses a hypereutectic casting process with increased silicon content to help reduce thermal expansion and improve wear resistance in demanding riding conditions. Its MOS2, or Teflon/molybdenum, coated skirts are applied through 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 reliable operation and protecting the piston crown.
An anodized dome improves heat resistance and durability for extended service life. The kit is configured for a 47.96 mm bore application and includes the related top-end components needed for installation. Verify the cylinder, year, and engine specifications before ordering to ensure proper fitment. The manufacturer part number is NX-30085-CK, and the vendor part number is 185-3085C.
Fitment: 2002-2009 Suzuki RM85 and 2020 Suzuki RM85, where applicable. Professional installation and inspection of the cylinder, crankshaft, and related engine components are recommended during top-end service.
