Motoz tubes are made from 100% high grade Natural Rubber. Designed to fit motorcycle tires at maximum volume, so they’re under the least amount of stress (not stretched when inflated).
The raw material used is #1 Smoked Rubber sheet, which stretches like a surgical glove and can be compressed under load without splitting. This is super important for avoiding pinch flats.
Many tubes are made of Butyl (synthetic) rubber which is artificial and lacks the natural characteristics, the stretching and compressing capabilities, of natural rubber, meaning that when butyl tube punctures, it tend to split and tear (and almost impossible to patch/repair – not what you want when you’re miles from home).
Natural rubber tubes repair and patch easily, and are a must for long distance riding. They aren’t cheap, but they aren’t expensive for what you get.
Available in 3 thicknesses: 1.6mm Standard, 3mm Heavy and 4mm Uber Duty
(1.6mm perfect for spare to carry on bike)
Both of these tubes are the same size (140-18). The one on the left is a standard 1.3mm tube. The one on the right is an uber duty 4mm tube.
