Michelin Bib Mousse Tire Tubes

The future of tube technology is here today. This evolution of riding makes getting an unexpected flat a thing of the past. 


  • Made from a multicellular butyl material, replaces conventional tubes, providing a pressure equivalent of approximately 13 psi (0.9 bar)
  • Specifically designed for offroad 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 onroad use
  • Bib Mousse may be used only with Michelin offroad tires, including StarCross MS2, StarCross MH2, S12, M12, H12 Enduro Comp III, EnduroStar, Baja and Desert. Because Bib Mousse is shaped for a perfect fit inside these Michelin tires, use of Bib Mousse with other brands of tires can lead to handling instability and possible destruction of Bib Mousse
  • Each Bib Mousse includes a tube of Bib Mousse Fitting Gel. Be sure to follow installation instructions supplied with the product
Fitment Notes & Exceptions
  • The 90/100-21 fits Starcross HP4 tires only
