The Namura NX-10026-4R piston rings are specifically designed for the Honda CR250R motorcycles manufactured between 1986 and 1996. These piston rings are suitable for engines with a piston bore diameter of 67.4mm. This ring set includes four rings: an oil control ring, two compression rings, and one top compression ring.
The oil control ring features a precise design with fine ribs and wire ends that effectively control oil consumption and prevent oil leakage. The outer edge of the oil control ring is lined with a specially formulated chrome alloy to ensure excellent seal performance.
The two compression rings are designed with optimized grooves to provide even pressure distribution across the piston surface. Each ring is made of high-quality, forged, heat-treated material for enhanced durability and performance. The compression rings are tapered to ensure proper ring end gap clearance during installation.
The top compression ring is a critical component in the engine's combustion process. It features a thin, yet strong design with a low-tension pressure band to ensure a tight seal between the piston and cylinder wall. The top compression ring is also made from high-quality, forged, heat-treated material to provide maximum durability and perfect sealing properties.
