Restore top-end performance with the Namura NX-70029K3 Top End Kit. Designed for select 125cc two-stroke engines, this standard-bore kit includes the piston, rings, wrist pin, circlips, top-end bearing, and gasket kit needed for a comprehensive top-end rebuild. The dual-ring piston is engineered for dependable fitment and service in compatible Husqvarna and KTM applications.
Feature: MOS2 (Teflon/molybdenum) coated skirts use a rolled-on application process that creates a strong, durable bond. The coating helps improve heat transfer, reduce friction, and minimize the risk of cold seizures. The piston also features a machined-smooth head designed to reflect combustion heat and reduce carbon buildup, helping protect the piston crown during operation.
Feature: Anodized dome construction improves heat resistance and durability, while the hypereutectic casting process increases silicon content for controlled expansion, enhanced wear resistance, and reliable performance at higher cylinder temperatures. These features make the Namura top-end assembly a practical replacement for worn or damaged original components.
