The Motobike Mas 70/100-19 front wheel motorcycle mousse insert is a professional-grade closed-cell nitrile rubber foam tire insert engineered for the front wheels of motocross bikes, pit bikes, youth dirt bikes, and lightweight off-road motorcycles. This front-specific mousse completely replaces the inner tube to eliminate pinch flats on the front end, reduce unsprung rotating mass, and deliver consistent steering precision through every corner.
Available in soft, medium, and standard density formulations, the 70/100-19 front mousse fits smaller-displacement and youth-oriented motorcycles with 19-inch front wheels. As a Tianjin, China-based B2B manufacturer, Motobike Mas offers OEM private labeling, custom hardness formulations, and direct factory wholesale pricing for dealers, distributors, and race teams worldwide.

A front tire flat at speed is significantly more dangerous than a rear flat — it causes immediate loss of steering control. The 70/100-19 front mousse insert eliminates this risk entirely. No pinch flats from square-edge landings, no puncture flats from rocks and thorns, and no valve stem failures. For racers on youth bikes and pit bikes, this means safer racing and no DNFs from front-end failures.
Reducing unsprung rotating mass on the front wheel dramatically improves steering response and suspension action. By eliminating the inner tube and allowing a lighter rim lock, the 70/100-19 front mousse reduces front wheel rotating mass by up to 40%. The result: lighter steering feel, reduced deflection off roots and rocks, and better front-end feedback to the rider.
Unlike pneumatic tires where front tire pressure changes with temperature and altitude, a mousse insert delivers consistent damping and steering characteristics from the first lap to the last. This predictability is especially valuable for younger riders developing their technique, as it removes the variable of changing tire pressure from the equation.
The 70/100-19 front mousse allows riders to run effective pressures as low as 8 psi with zero risk of pinch flats. On loose, wet, or sandy terrain this translates to more front-end grip and confidence in corner entry. The foam absorbs impacts that would collapse a tube at low pressure.
Once installed, the front mousse requires no maintenance for the life of the tire. No air pressure checks before practice, no valve stem concerns, no gauges needed. For parents of youth racers and pit bike riders, this simplifies race-day preparation significantly.
Selecting the correct mousse hardness for the front wheel is critical for both performance and safety. The wrong density can cause vague steering or excessive front-end deflection.
| Dichte | Wirksamer Druck | Bestes Terrain | Gewicht des Fahrers |
|---|---|---|---|
| Weich | 8-10 psi | Schlamm, Sand, Lehm, nasse Bedingungen | Under 50 kg |
| Mittel | 9-11 psi | Gemischtes Terrain, Allround-Einsatz | 50-70 kg |
| Standard | 10-12 psi | Felsig, hart, Wüste, hohe Geschwindigkeit | Over 70 kg |
This 70/100-19 front mousse insert fits all standard 70/100-19 front tires. This size is commonly found on:
| Faktor | Front Mousse Insert | Vorderes Innenrohr |
|---|---|---|
| Flache Prävention | 100% - keine Frontplatten möglich | Vulnerable to pinch flats, especially on landings |
| Präzision der Lenkung | Beständig im gesamten Rennen | Veränderungen bei Druck und Temperatur |
| Wartung | Null - installieren und vergessen | Prüfen Sie den Druck vor jeder Fahrt |
| Rotierende Masse | Tiefer (kein Schlauch + leichteres Felgenschloss) | Höher |
| Front-end safety | Kein plötzlicher Lenkungsverlust | Plötzlicher Kontrollverlust auf der vorderen Ebene |
| Schwierigkeiten bei der Installation | Moderate — same technique as rear | Einfacher |
| Anpassungsfähigkeit an das Gelände | Festgelegt durch die Wahl der Dichte | Einstellbar über Druck |
A 70/100-19 front mousse insert typically lasts between 200 and 500 racing miles, depending on terrain, rider weight, riding speed, and lubrication during installation. Front mousses generally wear more slowly than rear units due to lower heat generation.
Das ist wichtig: Never use petroleum-based lubricants on mousse inserts — they degrade nitrile rubber. Use only water-based mousse lubricant, especially on front wheel installations where proper seating is critical for safe operation.
| Aspect | Front Mousse (70/100-19) | Rear Mousse |
|---|---|---|
| Primary Demand | Steering precision & bump absorption | Traction & torque transmission |
| Weight Impact | Critical for steering feel | Critical for acceleration |
| Heat Generation | Lower (less braking/acceleration load) | Higher (driving load) |
| Flat Consequence | Immediate loss of steering control | Loss of drive, manageable |
| Typical Lifespan | Usually longer than rear | Shorter due to higher loads |

The 70/100-19 size is primarily a front wheel application, commonly found on youth motocross bikes (85cc-100cc class), pit bikes, and certain lightweight off-road motorcycles. The narrower 70 mm section width is designed for smaller front-end applications where lighter steering response is needed.
Normalerweise 200-500 Rennkilometer. Die vorderen Mousses halten oft länger als die hinteren, weil sie beim Bremsen weniger Wärme erzeugen als die hinteren Mousses.
Common applications include the Kawasaki KX85/KX100, KTM 85 SX, Husqvarna TC 85, Yamaha YZ85, Suzuki RM85, GasGas MC 85, and many 125cc-155cc pit bikes with 19-inch front wheels.
Yes. Many racers choose a mousse for the front wheel for safety and consistency while running a tube on the rear. However, running mousse on both wheels provides the best overall performance and flat protection.
The basic installation process is the same — the key difference is that proper seating is even more critical on the front wheel because any imbalance or improper seating will be felt through the handlebars as vibration or wobble.
