Hyssk Heavy Duty 2mm Thick Inner Tube — 14" TR4 Valve, 3.00/3.50-14, for CRF125/150, DRZ125/RM85, KX85/KLX140, TTR/YZ Dirt Bikes

Hyssk 2mm Thick Inner Tube for 14 inch tires

When you tackle mixed terrain with a dirt bike, the right inner tube matters as much as the tire and wheel. The Hyssk Heavy Duty inner tube is built for 14 inch rims with a TR4 straight valve, designed to pair with 3.00/3.50-14 rear tires. The added wall thickness delivers a robust feel that contributes to ride stability and predictable response on uneven surfaces.

This line includes a notable upgrade: after product research, Hyssk has moved to a 2mm wall thickness and is rolling branded packaging in Q1 2026. The result is a more consistent product presentation and a clearer, easily identifiable choice on shelves, alongside improved durability and a premium impression.

Safety and quality are central to the offering. Partner factories carry ISO9001, DOT, and E-Mark certifications, a level of verification that is not common for many competing brands. This emphasis on process standards helps ensure reliable materials and production quality, giving riders a sense of reassurance when installing the tube.

Practical benefits appear in real-world riding scenarios. A thicker wall is designed to provide steadier shock absorption and a steadier feel over small bumps, contributing to a smoother ride on rough or rocky routes. While individual results vary, the 2mm construction is aimed at minimizing puncture risk and maintaining consistent air control through long sessions.

Fit and compatibility are clearly communicated. The tube is intended for 3.00/3.50-14 rear tires and is compatible with a range of popular models including Honda CRF125/CRF150/CRF85, Suzuki DRZ125/RM85, Kawasaki KX85/KLX140, Yamaha TTR125/YZ85, and similar rear tire configurations. The TR4 straight valve is a common, straightforward choice for many wheel assemblies.
