MICHELIN Bib Mousse

Off-road solution for motorcycle tire punctures

Michelin Bib Mousse is Michelin's off-road solution to tire punctures.

As a great innovation in the off-road segment, Michelin Bib Mousse eliminates the risk of a tire puncture, contributing to an unmatched record of victories in Rally, Enduro and MX since its creation in 1983

How does it work?
Michelin Bib Mousse is not a puncture proof inner tube. It is an innovative foam-based technology that is inserted between the rim and the tire instead of a classic inner tube. Because of its foam composition, it can't go flat! It is lighter than a reinforced inner tube and provides a pressure equivalent of 13.05 psi.

With Michelin Bib Mousse you can enjoy your off-road rides* without worrying about tire punctures.

*Michelin Bib Mousse is only designed for off-road use and is not street legal.

MICHELIN Bib Mousse are intended for Rally, Enduro and MX use.
MICHELIN Bib Mousse should not often be stored at temperatures over 86°F, and temperatures above 104°F should be avoided all together.
MICHELIN Bib Mousse are designed for off road competition use fitted to Michelin tires. The successful fitting and performance of MICHELIN Bib Mousse in tire brands other than Michelin cannot be guaranteed.
Not designed for use on the public highway (NHS). The maximum speed for a tire with a MICHELIN Bib Mousse fitted is 80mph (129 km/h).
The date of first use of the MICHELIN Bib Mousse should be no later than 18 months from manufacture.
The MICHELIN Bib Mousse should be used within 6 months of first fitting. However, the lifespan of MICHELIN Bib Mousse varies considerably depending on the intensity of usage and the discipline practised. For example, the durability will be much shorter for Motocross than for Enduro.
Before a fast stage, we recommend you to warm up the tire and the MICHELIN Bib Mousse progressively at a moderate speed.
Apply MICHELIN Bib Mousse gel every time you put on or take off a MICHELIN Bib Mousse, both new and used:

To avoid degradation due to excessive heat, distribute the gel inside the tire without putting it on the tire beads or the rim at the rate of ½ tube on the front MICHELIN Bib Mousse and 1 full tube on the rear MICHELIN Bib Mousse.
To limit the risk of punctures due to pinching in off-road use (motocross, enduro, rally...), use the gel with an inner tube, at the rate of ½ tube per tire.

The rim must be in good condition. Check the spokes to prevent abnormal friction between the MICHELIN Bib Mousse and wheel.
Position a rim tape inside the wheel or, failing this, a piece of adhesive tape covering the spoke nuts.
Place the wheel on the fitting unit.
Place the MICHELIN Bib Mousse gel inside the tire. We recommend applying it with a brush (Avoid getting the gel on the tire beads: risk of rotation on the rim).
If necessary, apply vertical pressure on the tire to prise the beads apart.
Position the MICHELIN Bib Mousse inside the tire.
Lubricate the first tire bead and the part of the MICHELIN Bib Mousse that will be in contact with the rim (a Michelin liquid lubricant should be used).
Make sure there is no valve on the rim.
Put the first bead onto the rim. Start by positioning it in the rim well then use a fitting lever if necessary. Insert the MICHELIN Bib Mousse as far as it will go into the rim well.
Lubricate the 2nd tire bead.
First put the bead onto the rim using a fitting lever. Immobilize this lever and then use a 2nd lever around 12 inches from the first to continue inserting the bead. Immobilize this 2nd lever then use a 3rd one to continue positioning of the bead, etc... until the bead is fully in position.
To seat the beads of the tire correctly against the rim flanges, it is recommended to inflate it to approximately 50.7 psi using a rubber TL valve. The valve is fixed on the inflation connector and simply positioned over the valve hole in the rim.
