PERFECT
JEWELRY
- 110/90-19 (4.50 X 19) - 120/90-19 MOTORCYCLE INNER TUBES - These inner tubes are suitable for use on motorcycle tires that have a width of 110 mm (4.50 inches) to 120 mm (4.72 inches), and a rim size of 19 inches. For each pack, you will receive 2 natural rubber inner tubes
- STANDARD NATURAL RUBBER INNER TUBES - 1.6mm is the standard thickness for inner tubes. Softer and more pliable, natural rubber inner tubes will stay flexible throughout their lifespan, working with your tire instead of against it. They’re also more durable, resist permanent distortion, and have superior abrasion resistance.
- PINCH AND PUNCTURE-RESISTANT TUBES - Avoid explosive punctures and pinching that can cause both damages to your motorcycle and damages to you, the rider. The natural rubber tubes have high-puncture resistance and are evenly molded to prevent pinching. Aside from that, these 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 durable. 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 durable 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
