EXHAUST MUFFLER
The muffler reduces the noise of the exhaust gases, but it is an
integral part of the exhaust as well. As such, its conditions affect
the motorcycle performance.
When the noise on the exhaust is too high, it means that the
deadening material set on the holed tube inside the muffler is
deteriorated.
WARNING*: Check the deadening material
after every competition and replace it if
necessary.
