Mr. Wolfs Mousse Balls 2.0 Lunar – Front – Fits oversize 90/100-21″ – Contains 26 balls

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

Leveraging a patented modular structure and a revolutionary self-lubricating elastomer compound, this product arrives 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 via the two additional spare “balls” included in the package. With the 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 improved ride feel and enhanced control. 

Tested across Motocross, Enduro, Rally-Raid, Baja and Adventure disciplines, the MousseBalls 2.0 Lunar allow riders to dial-in tyre behaviour: remove balls for softer setups in extreme terrain, insert all for firmer configuration ideal for high-speed desert stages, or choose an intermediate number for mixed terrain. 

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