Delete this machine from profileSelect this machineIt doesn’t matter where you’re riding – nothing cuts a race or trail-ride short like getting a flat. It’s frustrating to miss a moto or have to turn around, and even more frustrating when you know it could’ve all been prevented with a dirt bike tube. Durable, dependable, and affordable, dirt bike tubes are an effective defense against flats.
When you order a dirt bike tube from RMATVMC.com, you have options. Not only do we stock top brands like STI, IRC, Sedona, and Bridgestone, we also stock different types and constructions of tubes in those brands and more. Order a Nuetech Nitro Mousse Foam Tube to skip the standard rubber, or choose from any type of heavy-duty tube you prefer. The point is, there’s a dirt bike tube to suit every type of rider and riding style.

lasts a decently long while. as long as you heavily apply lube it will last multiple tire changes. mousse feel changes the longer you run it, be prepared to adapt or buy new every tire change. feels like 10-12 psi roughly.

Great system, works as described and I've had no issues with multiple tire changes and 60 hours of use. I've heard some users experience slow leaks overnight but I have had the same consistent air pressure as to using a tube. I check pressures before the ride and it's always good. As the instructions say, use a liberal amount of soapy water which helps seal up everything.

Solidly made and robust, yet still easy to install.
