The NitroMousse NMS21-220 Plushie Soft Mousse Tube is a high-performance foam insert designed to replace a traditional pneumatic inner tube in compatible off-road motorcycle applications. Its 80/100-21 size provides a fit for select 21-inch front wheel and tire combinations, while the Plushie Soft compound is engineered to simulate approximately 6-8 psi for a compliant, controlled ride.
Manufactured by NitroMousse under the NITROMOUSSE brand, this mousse tube uses proprietary elastomer foam with millions of nitrogen-charged micro-cells. The closed-cell construction is 100% flat-proof, eliminating the common punctures, pinch flats, and air-pressure maintenance associated with conventional inner tubes. The NMS21-220 is intended for off-road motorcycles and should be matched to the motorcycle, wheel, tire, and manufacturer fitment requirements before installation.
