Engineered as a direct replacement for conventional inner tubes, the Michelin Bib Mousse utilizes a multi-cellular butyl material to maintain a consistent pressure equivalent of approximately 13 psi (0.9 bar). This specialized component is strictly designated for off-road applications, offering optimal performance at speeds up to 80 mph (130 km/h). Exceeding this velocity threshold risks significant heat build-up, which can cause rapid structural failure of the mousse and pose serious safety hazards to the rider. Consequently, the Bib Mousse is prohibited for use on public roads and must never be installed on motorcycles intended for on-road operation.
To ensure mechanical integrity and handling stability, the Bib Mousse is exclusively compatible with Michelin off-road tires. Its specific geometry is tailored to fit perfectly within Michelin tire casings; utilizing this product with tires from other manufacturers may result in improper fitment, handling instability, or potential destruction of the mousse. Each unit is supplied with a tube of Bib Mousse Fitting Gel to facilitate proper installation. Riders must adhere strictly to the provided installation instructions to guarantee correct application and safe operation.
