NitroMousse Nitro Mousse NMS21-220 Plushie Soft Mousse Motorcycle Tube 80/100-21 Flat Proof Foam Insert

OVERVIEW

The NitroMousse NMS21-220 Plushie Soft mousse tube is a foam-based motorcycle tire insert engineered to eliminate flats while maximizing grip and ride comfort. Constructed from proprietary elastomers, this durable replacement delivers consistent pressure compliance without relying on pressurized air. It serves off-road machines, specifically those equipped with 80/100-21 front tires.

ENGINEERING & PERFORMANCE

Filled with millions of nitrogen‑charged micro‑cells suspended in proprietary elastomers, this high‑performance foam insert maintains steady pressure and shock absorption regardless of track conditions. The open‑cell compound absorbs impacts over rocks and roots without bottoming out, while completely removing the threat of punctures or pinch flats. Because it eliminates internal air pressure, riders maintain precise steering feedback and predictable handling through tight, technical sections at low speeds.

KEY FEATURES

• Proprietary elastomer construction with nitrogen‑charged micro‑cells

• Plushie Soft compound simulates 6–8 psi ride pressure
• Enhanced traction and damping on technical, rocky surfaces
• Optimized for enduro, trail, and hard‑enduro motorcycle applications
• Front tire application for 80/100‑21 size wheels

WHY RIDERS CHOOSE THIS

Riders choose the NitroMousse Plushie Soft insert to lock in consistent traction and eliminate downtime caused by flats or sudden air loss on rough trails. The nitrogen‑infused foam matrix absorbs chassis shocks more effectively than traditional air tubes, delivering plush compliance without sacrificing steering precision. By maintaining a fixed 6 to 8 psi simulation, the insert keeps the tire footprint stable during rock crawling and low‑speed maneuvers. This predictable handling directly translates to faster lap times and reduced rider fatigue on dedicated dirt bikes.
