Dunlop FM21S-NP Front Tire Mousse for 80/100-21 Tires

The Dunlop FM21S-NP Front Mousse is a purpose-built tire insert designed for powersports riders seeking consistent, reliable support in off-road applications. Engineered for use with 80/100-21 front tires, this mousse insert replaces conventional air pressure with a resilient internal support system that helps maintain a predictable ride feel across changing terrain.

As part of Dunlop's FM21S-NP mousse range, this front insert is suited to riders who value puncture resistance and reduced trail-side maintenance. It eliminates the concern of air loss from common punctures, helping provide dependable performance during recreational riding, racing, and other demanding off-road use. The insert is designed to work with compatible tire and wheel combinations, so proper installation and fitment verification are essential.

The Dunlop FM21S-NP is supplied as a single front mousse insert. Its construction is intended for powersports applications and should be installed using appropriate mousse-specific lubricants and procedures. Mousse inserts are not intended to be treated as conventional inner tubes and may require a break-in period before reaching their intended operating feel. Always follow Dunlop's installation guidance and confirm compatibility with the tire, wheel, and riding conditions before use.
