FAQ

General Mousse Information

What is the rim width?

Different bikes have different rim widths and it is usually associated with the engine displacement.  While most front rim widths are standard (1.60”), the rear can vary.  A 250F will generally have a rim width of 1.85”, while a 450F will have a rim width of 2.15”.  To find the rim width of your bike, look at the rims carefully and there will usually be a stamp on the rim itself that says what the width is, example: 2.15”X18”.

Is a mousse better than the TUbliss system?

Mousses are 100% flat proof, if this is your top priority, then it might be a better choice. The TUbliss is designed to improve on every aspect of performance, protection and adjustability compared to a tube. If you want the security of not getting a flat, then a mousse is probably best for you. If you want the ultimate in performance and adjustability, then the TUbliss is the better option.

How do I know when to replace a mousse?

When a mousse breaks down and starts to deteriorate, it will rapidly start to feel much softer and unstable, similar to a tube that is slowly leaking and going flat. You will also experience excessive tire roll and less resistance to impacts. It is VERY IMPORTANT to pay attention to this and replace the mousse before it becomes too soft or unstable for safe riding.

Should I use a standard rim lock with a mousse?

Yes, even though some manufacturers do not recommend using a rim lock, we think it is an important safety measure and highly recommend using a proper fitting and functioning rim lock. During operation and especially in warm temperatures, a typical or improperly sized mousse can expand and pop the tires bead off the rim. DO NOT MOUNT a Nitromousse without a proper fitting and functioning rim lock.

Does outside temperatures affect the feel of a mousse?

Yes, a standard mousse is extremely impacted by outside temperatures. Cold temperatures can cause a very stiff, harsh feel and reduce traction, similar to riding with excessive psi pressure in a tube. Additionally, very warm temperatures can result in an overly soft unstable feel, causing additional tire roll/push in cornering, and excessive drag during acceleration and braking.
Nitromousse has been designed and tested to be much more consistent, severely limiting the effects that can be caused by wide temperature ranges.

Do mousses need a break in period?

Yes, a typical mousse will need a few hours of riding to get an optimum performance feel. However, this performance zone typically diminishes quickly as ride hours progress leaving you with and overly soft and unpredictable feel in motion. This is uncorrectable as a mousse or foam insert is non-adjustable other than adjusting themselves as they diminish and wear. Nitromousse does NOT need a break in period like other mousses – NOTE: Although a Nitromousse does not need to be broken in, when mounting with a new or ultra stiff tire, there can be an initial firmness to the feel and ride until the tire heats up and wears in a bit.

How long will a mousse last?

The anticipated life span of a mousse can vary depending on several factors, some of which are average operating speeds, intensity of terrain ridden on, proper lubrication, and outside or operating temperatures. This can typically be determined by how they are used. Excessive high speed and or aggressive riding in very warm temperatures has the highest wear factor for a mousse, but it is not uncommon for them to last several tires or more than a year.
Nitromousse proprietary compounds allow them to last twice as long as other mousses.

Are mousses heavier than tubes?

Yes, a mousse is heavier than a standard tube, but closer to the weight of a heavy duty tube. Traditionally mousse users are willing to trade the weight difference for the elimination of flats. Nitromousse’s nitrogen charged livelier feel makes this weight difference less noticeable.

How many PSI is a mousse equivalent to, when compared to a traditional tube?

A typical new mousse should feel similar to approximately 12-13psi of tire pressure. This can vary slightly due to tire selection, mousse sizing, and outside temperatures.
Nitromousse is designed to have a much lower, plusher, more progressive and controlled pneumatic feel, without a break-in period (NOTE: when used with a new tire, the tire itself may have a break in period though).

Are mousses for racers only?

No, mousses can be used by any level off-road rider whose primary concern is eliminating flat tires.
Nitromousse makes the transition to mousses much easier because of increased performance and better, more pneumatic, feel.

What is the Nitromousse "HIGH PERFORMANCE" Difference?

What is the NITROMOUSSE “HIGH PERFORMANCE” DIFFERENCE?

We have put in years of extensive research and development into designing, building and improving all aspects of a “High Performance” off road foam insert. Nitromousse enhances the positives while reducing the negatives:

  • Nitromousse uses an incredibly tough micro-matrix of proprietary elastomers Increasing Durability, allowing Nitromousse to last up to 2X longer than other mousses.
  • Nitromousse contains a high concentration of Nitrogen which gives it a much Plusher, Pneumatic (air) feel, eliminating the dreaded “Dead Feel”.
  • The Nitrogen formula gives the Nitromousse a Low Pressure Predictable ride, Resisting Impacts and increasing Bump Absorption.
  • The Nitromousse compounds allow for a Livelier, Progressive ride eliminating Deflection and providing a Lighter feel in motion.
  • Nitromousse does not need a Break In Period and has been designed and tested to Perform Consistently in Temperature ranges from 30-100+ Degrees.
  • Nitromousse’s Performance and Durability all come at an Exceptional Price.

Installation

What should I do with the second hole in the rim that was originally used by the tubes valve stem?

Make sure that any extra Holes in the rim that are not used by the rim lock are plugged so that the mousse lube does not escape, or debris cannot enter the rim. This can be done with rim tape prior to mounting the mousse.

Why do I need to lube my Nitromousse prior to each installation?

Lube reduces the friction between the inside of the tire and Nitromousse during operation. Use all of the supplied lubricant when mounting or Remounting a Nitromousse. Apply half of the supplied tube of lube to the inside of the tire and the other half to the outside of the mousse. Never mount a Nitromousse without proper lubrication, this will cause severe premature wear, or can cause the mousse to fail completely. Never mount a Nitromousse without proper lubrication.

Why can’t I get the tire’s bead to seat properly on the rim?

This can be a common occurrence and these are some ways you can remedy the issue:
1. Take a couple tire irons or the bead breaker arm on a tire mounting stand and push down on the tire near the bead that won’t seat.
2. Stand the wheel up vertically, pick it up about waist high and bounce the wheel while rotating it a couple times.
This will generally fix the issue and pop the bead into place, sometimes however, it may require a short low speed ride to allow the mousse and tire to adjust and seat on the rim.

What tools are needed to mount a Nitromousse?

We recommend at the very least, 3 larger tire irons/spoons, 3 short tire irons/spoons, and 1-2 bead holding tools (bead buddy) or vice grips. More tire irons and/or a tire mounting stand with bead breaker arm can make this easier but are not necessary. If you do not have correct tools or are not confident in installing or changing a mousse, we strongly recommend that you have a qualified shop or mechanic perform the installation for you.

Is a mousse hard to install?

As with installing any off road motorcycle tire for the first time or two, it can be difficult until you develop the proper technique, but it is not a difficult process to learn. If this is your first time, please read all instructions and view our installation instruction videos for reference. You may also want someone to assist you. If you do not have the correct tools or are not confident in installing or changing a tire or mousse, we strongly recommend you have a qualified shop or mechanic perform the installation for you.
