OVERVIEW

This heavy-duty inner tube delivers reliable air retention and puncture resistance for motorcycles, dirt bikes, and pit bikes running 14-inch rear wheels. Constructed with reinforced rubber and a 2mm wall profile, it provides the durability riders need for aggressive off-road riding. Designed to replace worn tubes on compatible 4.10-14, 90/100-14, 90/90-14, and 3.60-14 tire sizes, this Mitas accessory ensures stable performance in rocky terrain and high-impact environments.

ENGINEERING & PERFORMANCE

The 2mm-thick rubber casing resists cuts and abrasions caused by sharp rocks, roots, and rough trails, extending service life under demanding conditions. Its galvanized metal TR-6 valve stem offers superior structural integrity compared to standard rubber valves, maintaining steady pressure through vibrations and temperature fluctuations. Each unit is stored in nitrogen-rich packaging to prevent internal oxidation and preserve elasticity, while the included mounting washers and dual valve caps ensure a secure, leak-free seal during installation.

WHY RIDERS CHOOSE THIS

Riders select this Mitas tube when stock rubber fails prematurely under trail stress. The thickened 2mm walls absorb impacts that typically split thinner tubes, while the hardened metal valve eliminates flex and slow leaks at the core. Mounting remains straightforward thanks to consistent dimensional tolerances across all four approved tire sizes and the inclusion of essential hardware. For motocross and pit bike operators who prioritize longevity and consistent air pressure between runs, this tube delivers dependable service without the downtime of frequent replacements.
