WHAT IS A MOUSSE
EXPLAINATION: A “Mousse” – (“mousse” is French for foam), simply put is just a solid foam inner tube. They were originally introduced to the off road motorcycle market in 1984 by the French tire company Michelin. There are several companies over the years that have created different formulations of a mousse, however the composition and nature of the foam can have a huge impact on performance and longevity, so not all mousses are equal.
PROS AND CONS: In general a mousse is known to do one thing very well, NOT go flat. However they are also known to have several downsides, such as having a slow rebounding or non-progressive effect in their rideability. In the industry, this is often referred to as a “DEAD” feel. This loose or unstable feeling can affect the motorcycles handling and traction applications and unfortunately you just have to live with it because they are not adjustable (Like pneumatic systems or inner tubes), other than that they do adjust themselves as they diminish and wear. Being a solid foam unit, mousses are generally heavier than most tubes, and the dead feeling only contributes to this effect and feel. Other negatives can be their short life span, made worse by their high cost (Nitromousse is a big improvement compared to past mousses).
