The Kenda Standard 21-Inch Inner Tube is designed for reliable replacement and service applications requiring a TR-6 center metal valve. Manufactured by Kenda and identified by manufacturer and vendor part number 05214020, this butyl rubber tube provides dependable air retention and durability for compatible tires and wheels.
Each tube is packaged in an individual box, with the correct tube size and valve-stem type clearly marked for easier identification and installation. The center metal valve configuration supports applications that specify a TR-6 valve stem, helping ensure proper fitment when matched to the tire and wheel requirements.
Before installation, confirm that the tire accepts a 21-inch inner tube and that the wheel is designed for a TR-6 center metal valve. Inspect the tire, rim, and valve opening for damage or debris, and replace the tube whenever it shows signs of wear, puncture, or deterioration. The Kenda brand delivers a practical replacement solution for compatible motorcycle, powersports, and other applicable tire assemblies.
