Features

  • 100/90-19 (4.10 X 19) MOTORCYCLE INNER TUBES - These inner tubes are suitable for use on motorcycle tires that have a width of 100 mm (4.10 inches to be exact) 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. Theyre 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 thats compatible with most hand pumps. Similar to the tubes, the TR4 valve stems are durable. Theyre 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.

    • Good Thin Inner Tubes
Size: 110/90-19 (4.50 x 19)
Good cheap inner tubes. I like these because they are thinner than most to keep the un-sprung wheel weight down.

I've had good luck with these inner tubes, but this is also the only inner tube I've ever blown up when setting the bead. Was it probably my fault? Absolutely. Could it have been because it's a weaker product then the more well known competition? Also possible. Still overall, I've had good luck and recommend them. ... show more

    • Good value for the $
Size: 110/100-18 (4.50 x 18)
It's a tube. Made in China as all others. Did not blow or ripped during my install, so I got to believe it will last. Importantly, you get two tubes for a price that you might barely get one from some competitors. Worth a try!
