TIPP: You can use the BGM Vespa tubes on many other vehicles with ten-inch tube-type tires. Use mounting paste on the bulge to fit the tire and sprinkle the inner side of the wheel with talc. Mounting paste ensures the correct final position of the tire, while talc minimises friction of the tube.
Thus maximising safety and endurance of the tube.
NOTE: Tubes with a smaller butyl ratio have a higher percentage of rubber, which leads to more flexibility. They can therefore be used for a wider range of possible tire sizes (up to 130/90-10). You'll have to deal with the disadvantage of the tires been a lot less airtight. We have decided in favour of higher quality for tire sizes up to 100/90-10.
