OVERVIEW

This Mitas standard duty inner tube delivers reliable air retention and consistent wheel sealing for motorcycles, scooters, and mopeds. Constructed from durable 1.5 mm rubber, it balances flexible sidewall travel with the structural integrity needed to hold steady pressure. The tube is engineered specifically for 18-inch wheel rims, serving as a direct, cost-effective replacement for worn seals across commuter platforms and light trail machines.

ENGINEERING & PERFORMANCE

The 1.5 millimeter standard-duty rubber wall maintains stable internal pressure while flexing smoothly during vibration-heavy operation and sharp cornering. Controlled material thickness helps manage heat build-up, reducing the risk of premature seam stress or sidewall cracking. A galvanized TR-6 center metal valve prevents stem corrosion and ensures a tight, leak-resistant fit against steel or aluminum rim bores. The included dual rim washers lock the valve base securely, eliminating slow air loss at the mounting interface.

WHY RIDERS CHOOSE THIS

Riders select this Mitas replacement tube because it pairs a proven rubber compound with a straightforward valve layout that speeds up bench mounting and reduces installation errors. The galvanized stem and gasket hardware cut the chances of valve-seal leaks, which are a common source of recurring flats on older or heavily used wheels. Because it accommodates a wide range of standard 18-inch tire widths, mechanics can stock one reliable unit to cover daily scooters, trail bikes, and small-displacement commuters. The nitrogen-shielded retail packaging keeps the rubber fresh until deployment, guaranteeing consistent elasticity when you need it most.
