Kibblewhite Offroad C630 Racing Bronze Valve Guide Std Fits Honda XR

• Type: Valve Guide

This precision-engineered valve guide is designed for Honda XR models and is optimized for high performance and durability. Made from premium C630 Racing Bronze, a material with 80% copper, 5% nickel, and 10% aluminum, it offers excellent thermal conductivity, superior wear resistance, and corrosion protection. The material's high copper content improves heat dissipation, while the nickel and aluminum make it compatible with aluminum cylinder heads. The guide's aerodynamic profile minimizes airflow obstruction while maintaining critical thickness in high-temperature areas. Its design can enhance airflow even without additional modifications. For ease of installation, features like a flange (where applicable) set the correct protrusion height, eliminating the need for repeated measurements. A radius transition at the nose prevents galling during installation, and tight concentricity tolerances ensure optimal geometry between the valve seat and guide, reducing seat material removal and maintaining consistent chamber volumes during valve jobs. This valve guide is specifically engineered for high-performance off-road applications, offering superior oil control and an improved valve-to-seat seal. Sold in sets of two unless otherwise specified, it is a reliable choice for riders seeking durability and precision in demanding conditions.
