The Motobike Mas 110/90-19 motocross mousse insert is a professional-grade foam tire insert engineered for motocross, enduro, and dirt bike racing applications. Made from closed-cell nitrile rubber foam, this mousse insert completely replaces the inner tube to eliminate pinch flats, reduce rotating mass by up to 40%, and deliver consistent performance across varying terrain.
Available in soft, medium, and standard density options, the 110/90-19 mousse fits full-size 250cc-450cc motocross and enduro rear tires. As a B2B manufacturer based in Tianjin, China, Motobike Mas offers OEM private labeling, custom hardness formulations, and direct factory wholesale pricing for dealers and distributors worldwide.

The single most important advantage of a mousse insert is absolute flat prevention. Inner tubes are vulnerable to pinch flats from square-edge impacts, puncture flats from thorns and sharp rocks, and valve stem failures. A solid foam mousse eliminates all three failure modes. For motocross racers this means no DNFs from flats, for enduro riders no trailside tire changes, and for race teams no lost positions due to tire failure.
Rotating mass at the wheel’s outer edge is the most impactful weight in motorcycle dynamics. A mousse setup eliminates the inner tube and allows a lighter rim lock, reducing unsprung rotating mass at the rear wheel by up to 40%. The result: quicker acceleration out of corners, reduced gyroscopic effect for easier direction changes, and less strain on suspension components.
A mousse insert is unaffected by temperature — its damping characteristics remain consistent from the first lap to the last, allowing racers to fine-tune suspension without the variable of changing tire pressure. This predictability is especially valuable in multi-hour enduro and hare scramble events.
Mousse inserts allow riders to run effective pressures as low as 8 psi without any risk of pinch flats. In muddy, wet, or loose terrain, this translates directly to more traction. The foam absorbs impacts that would otherwise collapse a tube at low pressure.
Once installed, a mousse insert requires zero maintenance until the tire is worn out. No air pressure checks, no valve stem inspections, no pump in the hydration pack. For racers, this means one less thing to think about on race day.
Selecting the correct mousse hardness is critical for optimal performance. The wrong density can result in a harsh ride or excessive wear and overheating.
| Densidade | Pressão efetiva | Melhor terreno | Peso do ciclista |
|---|---|---|---|
| Suave | 8-10 psi | Lama, areia, solo franco, condições húmidas | Menos de 75 kg |
| Médio | 9-11 psi | Terreno misto, utilização versátil | 75-90 kg |
| Padrão | 10-12 psi | Rocoso, com solo compacto, no deserto, a alta velocidade | Mais de 90 kg |
This 110/90-19 mousse insert fits all standard 110/90-19 rear tires on full-size motocross and enduro bikes including:
| Fator | Mousse Insert | Inner Tube |
|---|---|---|
| Prevenção de furos | 100% — no flats possible | Vulnerable to pinch flats, punctures |
| Manutenção | Zero — instale e esqueça | Verifique a pressão antes de cada passeio |
| Massa rotativa | Inferior (sem tubo + fecho de aro mais leve) | Mais alto |
| Traction | Consistente ao longo de toda a corrida | Alterações em função da pressão e da temperatura |
| Dificuldade de instalação | More difficult | Mais fácil |
| Reusability | Transfer to new tire (if in good condition) | Replace each tire change |
| Adaptabilidade ao terreno | Resolvido através da escolha da densidade | Ajustável por meio de pressão |
| Weight penalty | Reduces unsprung mass | Baseline |
A 110/90-19 mousse insert typically lasts between 200 and 500 racing miles, depending on terrain, rider weight riding speed, and lubrication during installation.
Importante: Never use petroleum-based lubricants on mousse inserts — they degrade nitrile rubber. Use only water-based mousse lubricant.

Typically 200-500 racing miles depending on terrain, rider weight, and maintenance. Hard terrain and heavy braking accelerate wear.
Yes, if the mousse is still within its serviceable condition (no tears, proper density), it can be transferred to a new tire of the same size.
Yes. Mousse inserts must be installed with specialized water-based mousse lubricant to prevent tearing and ensure proper seating inside the tire casing. Never use petroleum-based lubricants.
The 110/90-19 mousse performs equivalently to 8-12 psi depending on the hardness option selected.
No. 110/90-19 is for rear wheels only. For front applications use a 90/90-21 or 80/100-21 mousse insert.
They are the same product. “Mousse insert” and “bib mousse” are interchangeable terms for nitrile rubber foam tire inserts used in off-road motorcycle racing.
