MousseBalls 2.0 Lunar – Front – 90/90-21″ and 80/100-21″ – Contains 26 balls

The Mr.WOLF MousseBalls 2.0 Lunar (SKU MBL-1000) represent the next evolution in off-road tyre insert technology. Designed for front wheels in 80/100-21″ and 90/90-21″ sizes, this module contains 26 individual MousseBalls, enabling full adaptability of wheel hardness according to terrain and rider preference. For larger oversize fronts (90/100-21″) please use SKU MBL-1000-BIG.

Thanks to a patented modular structure and a revolutionary self-lubricating elastomer compound, these mousse modules arrive ready to install straight out of the box—no grease, no gel, no extra mess. 

Built for both amateur and professional riders, the Lunar series guarantees extended lifespan with the option to regenerate the set by replacing individual balls included as spares. With a sector-structure delivering a higher surface-to-volume ratio, operating temperatures can drop by up to 33% compared to traditional mousse systems, reducing hysteresis and vibration for a cleaner ride feel and better control. 

Tested across Motocross, Enduro, Rally-Raid, Baja and Adventure disciplines, the MousseBalls 2.0 Lunar allow riders to dial in tyre behavior: remove balls for softer setups in extreme enduro, insert all balls for firmer desert-stage performance, or pick an intermediate number for mixed terrain. 

Whether you’re racing hard or exploring trails, the MBL-1000 offers a front-wheel insert that blends the versatility of an inner tube with the safety and performance of a mousse—with none of the usual compromises.
