MEFO MOM 18-4 Foam — designed for rally, enduro, and motocross riders looking for a lightweight and reliable solution for the rear wheel. Compatible with 150/70-18 and 140/80-18 Rallye Special tires, this foam adapts to the internal volume of the tires to maintain consistent off-road handling without the constraints of a traditional inner tube.
MEFO is the only manufacturer that adjusts the diameter of the section of its foams based on the internal volume of the tires and offers foam structures tailored to each discipline. Practical advantage: the foam reduces weight compared to a reinforced inner tube and decreases the risk of punctures in off-road conditions. Indicative pressure equivalence: 0.8 - 0.9 bar, making it easier to adjust handling and grip according to the terrain.
Ideal for enduro outings and rally specials, the MOM 18-4 provides a robust alternative for those riding on trails, obstacles, and dirt tracks, while remaining compact and easy to mount on a compatible rim.
