The NitroMousse Platinum Standard Mousse Tube NM21-220 is a high-performance foam inner tube designed to replace traditional pneumatic inner tubes in compatible off-road motorcycle tires. Manufactured by NitroMousse, this flat-proof tube uses proprietary elastomers containing millions of nitrogen-charged micro-cells to provide dependable support without air pressure loss or punctures.
The Platinum Standard model simulates approximately 10–12 psi, offering a balanced combination of traction, stability, and impact protection for demanding trail and off-road riding. Its foam construction helps eliminate common inner-tube failures caused by pinch flats, punctures, and sudden pressure loss. The NitroMousse NM21-220 is sized for 21-inch front tire applications using 80/100-21 or 90/90-21 fitments.
Designed for off-road motorcycles, the NitroMousse Platinum Standard Mousse Tube provides consistent performance in a wide range of riding conditions. It is not an inflatable tube and should be installed using proper mousse-tube mounting procedures, including suitable tire-mounting lubricant. For best results, verify tire compatibility and application requirements before installation. This product is manufactured by NitroMousse and identified by manufacturer and vendor part number NM21-220.
