Description

Designed for the demanding conditions of motorcycle riding, the PARTS UNLIMITED Standard Inner Tube provides a robust and dependable foundation for your tires. Unlike many "butyl" tubes that blend butyl polymer with natural rubber, this tube is composed entirely of high-grade butyl polymer. This advanced material composition significantly minimizes natural air leakage, a common issue with lesser quality tubes, thereby extending the time between air pressure checks and enhancing ride safety and performance. With a sturdy 2.0 mm thickness, it offers excellent puncture resistance for both front and rear wheel applications. This inner tube is specifically designed to fit 18-inch rims and is compatible with tire sizes 3.50-18 and 4.00-18, making it a versatile choice for a wide range of motorcycles. Equipped with a reliable TR-4 (Round Base) center metal valve, it ensures secure inflation and consistent pressure.
