✓3MM THICK BUTYL RUBBER INNER TUBES - On the upper end of heavy-duty inner tube thickness, our butyl rubber inner tubes offer superior shock and vibration damping for a more comfortable ride, even on rough terrain. The thick butyl rubber inner tubes are also more airtight than average inner tubes
✓PINCH AND PUNCTURE-RESISTANT TUBES - Avoid explosive punctures and pinching that can cause both damages to your motorcycle and damages to you, the rider. These sturdy inner tubes are puncture-proof and evenly molded to prevent pinching. Aside from that, these thick inner tubes also resist twisting and splitting from the valve stem base
✓TR4 VALVE STEMS - The short, straight, and threaded stems of the TR4 valves provide both convenience and safety. TR4 is a standard valve stem that’s compatible with most hand pumps. Similar to the tubes, the TR4 valve stems are heavy-duty. They’re also securely seated in the tubes through vulcanization.
✓DESIGNED FOR OFF-ROAD AND MOTORCROSS TIRES - Dirt bikes, off-road motorcycles, motocross motorcycles need the comfort and protection of heavy-duty motorcycle inner tubes. These inner tubes are designed to withstand even the roughest of tracks, making them the best and most cost-effective replacements for the inner tubes.
