ALLOW ONLY TRAINED PERSONNEL TO INSTALL INNER TUBES. WARNING BIB MOUSSE ® • Made from a multi-cellular butyl material, Bib Mousse replaces conventional tubes, providing a pressure equivalent of approximately 13 psi • Specifically designed for off-road competition use, at speeds up to 80 mph (130 km/h) – above this speed, heat buildup can lead to rapid destruction of the Bib Mousse, resulting in serious injury to the rider – under no circumstances should Bib Mousse be fitted to motorcycles for on-road use • Bib Mousse may be used only with Michelin off-road tires, including StarCross HP4, StarCross MS3, StarCross MH3, S12 XC, M12 XC and Desert Race – because Bib Mousse is shaped for a perfect fit inside these Michelin tires (see sizing chart below); use of Bib Mousse with other brands of tires can lead to handling instability and possible destruction of the Bib Mousse • Each Bib Mousse includes a tube of Bib Mousse Fitting Gel; installer must be sure to follow installation instructions supplied with the product • Gel also available separately in a box of 12 50-gram tubes BIB MOUSSE ™ MOUNTING GEL • Use when installing or reinstalling a Michelin Bib Mousse • 50 gram tube • Sold as 12-pk MOUSSE TUBES • Toroidal-shaped expanded-foam inserts replace the traditional inner tube on off-road motorcycles • Technically the Mousse is a butyl ring with a honeycomb structure, the cells of which are filled with gas so as to simulate the effect of an inner tube • The Mousse is surrounded by a thin external membrane designed to make it easy to fit on different sized tires • A Pirelli Mousse is a technologically advanced product, characterized by the presence of self-pressurizing agents capable of creating a very large number of gas bubbles inside the mousse, making the product immune to punctures • Immune to punctures and abrasions; developed by Pirelli for riders who compete in every kind of competition, whether it be a race in the desert or a Cross championship trial TIRE SIZE RIM SIZES PART # SUG.
