OVERVIEW

The Mitas 70001345 is a heavy-duty motorcycle inner tube built for durability and consistent air retention across a broad range of tire specifications. Designed for use on motorcycles, scooters, and mopeds, this component features a 2-millimeter wall thickness to resist punctures and mechanical abuse. The assembly relies on a TR-6 valve system with a galvanized metal stem to provide secure mounting and long-term corrosion resistance.

ENGINEERING & PERFORMANCE

The reinforced 2-mm wall construction absorbs road shock and debris impacts while maintaining stable pressure distribution inside the tire casing. Galvanized valve stems prevent oxidation and loosening under vibration, keeping the inflation point secure over thousands of miles. Manufacturing in a nitrogen-rich atmosphere protects the rubber compound during warehousing, ensuring the tube arrives ready to perform without age-related degradation.

WHY RIDERS CHOOSE THIS

Riders choose this tube when standard replacements fail to handle rough terrain or high-mileage abuse, needing the added protection of a 2-millimeter wall thickness. The galvanized metal valve stem addresses common failures caused by rust and seized cores, especially on exposed rims where moisture and dust accumulate quickly. Including washers and dual-valve caps streamlines the installation process, giving riders a complete kit that reduces leak risks and improves airflow security. This attention to detail makes it a reliable choice for dirt-sensitive applications, scooters, and mopeds where spare time maintenance is not an option.
