Performance & Ride Feel
Reliable rear-wheel performance is especially important for junior riders. A puncture or sudden pressure loss can immediately affect traction, stability and braking, potentially ending a ride or race. The solid cellular construction of a mousse removes the air chamber found in a conventional inner tube, so there is no air pressure to lose.
The approximate 12–13 psi feel provides a useful balance between tyre support and terrain conformity. This allows the rear tyre to respond predictably across loose dirt, acceleration bumps, ruts, hard-packed surfaces and changing motocross track conditions.
Consistent tyre support helps maintain predictable traction throughout the ride without needing to check or adjust air pressure. Correct tyre compatibility, installation and lubrication remain essential for achieving the intended feel and performance.
Compatibility & Fitment
This mousse is designed for compatible 80/100-12 and 90/100-12 rear tyres. Tyres carrying the same marked size can have different internal dimensions, carcass profiles and construction, so mousse compatibility should always be confirmed before installation.
Correct fitment helps produce the intended 12–13 psi feel while reducing unnecessary movement, heat and premature mousse wear. Do not select a mousse using rim diameter alone.

German-Made Quality
Manufactured in Germany using high-quality materials, Mefo Mousses are trusted for their consistent performance, dependable fitment and long service life. Their cellular construction is designed to handle the repeated impacts, deformation and heat generated during demanding off-road riding.
Installation & Care
Mousse gel is included for the initial installation. Apply the entire sachet evenly during fitting to reduce friction and heat between the mousse and tyre.
Periodically remove, inspect and re-lubricate the mousse to help maintain flexibility and maximise service life. Riding speed, terrain, temperature, tyre construction, lubrication and storage conditions can all affect mousse wear.
Use suitable mousse-fitting tools and take care not to damage the tyre bead or mousse during installation. Professional installation is recommended if you are unfamiliar with fitting mousse tubes.
Use Rim Locks
Rim locks are strongly recommended to help prevent the rear tyre from moving on the rim during acceleration, braking and demanding off-road riding. Correctly installed rim locks support consistent performance and help keep the tyre securely positioned.
Off-Road Use Only
This mousse is designed specifically for junior motocross, minicross and off-road riding. It is not intended for extended highway or high-speed road use, where sustained heat can shorten mousse service life.
