Inner Tube 130/60-13 - straight valve

Inner Tube

Modern two-wheelers are almost always equipped with tubeless tires, but on mopeds as well as motocross and enduro bikes you can still find inner tubes. Tire tubes are often used on spoked wheels, with the exception of supermoto tires.

To avoid punctures, be sure to use rim tape to prevent the spokes (which move when the road or track is uneven) from puncturing the tube.
In motocross and enduro competitions, it is also essential to use a rim lock. Otherwise, the tire can slip on the rim and tear the valve from the tube.
