OVERVIEW

The MITAS 70001318 Standard Duty inner tube provides reliable air retention and puncture resistance for 12-inch motorcycle, scooter, and moped wheels. Constructed from 1.5 mm thick rubber, this essential wheel component delivers straightforward replacement performance without unnecessary weight or structural complexity. Each unit ships individually pouches packed in a nitrogen-rich atmosphere to preserve rubber elasticity until installation.

ENGINEERING & PERFORMANCE

This 12-inch inner tube maintains consistent pressure across light off road and urban commuter applications when mounted inside its designated tire sizes. The heavy duty 1.5 mm casing resists abrasion and pinch flats during aggressive cornering, quick launches, and uneven pavement. A centered galvanized steel TR-4 valve stem ensures secure alignment, while the dual sealing washers and protective caps prevent corrosion, rim threading damage, and slow valve-core leaks.

WHY RIDERS CHOOSE THIS

Riders select this standard duty tube because it simplifies routine wheel maintenance with a direct bolt-on fit and uncompromising seal reliability.

Its center mount valve configuration aligns perfectly with stock 12-inch rims, eliminating valve bend risks during tire removal and installation. Packaged to retain structural integrity straight from the box, it delivers steady holding power without break-in periods or specialized storage requirements.
