Professional 110\/90-19 Motocross Mousse for Extreme Off-Road Performance<\/h2>\n

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.<\/p>\n

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.<\/p>\n

Key Benefits<\/h2>\n

Complete Flat Prevention<\/h3>\n

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.<\/p>\n

Rotating Mass Reduction<\/h3>\n

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.<\/p>\n

Consistent Race-Long Performance<\/h3>\n

A mousse insert is unaffected by temperature \u2014 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.<\/p>\n

Run Lower Effective Pressures<\/h3>\n

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.<\/p>\n

No Maintenance During Tire Life<\/h3>\n

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.<\/p>\n

Hardness Options Guide<\/h2>\n

Selecting the correct mousse hardness is critical for optimal performance. The wrong density can result in a harsh ride or excessive wear and overheating.<\/p>\n\n\n\n\n\n\n
