Product Review: Weapon MX Tank G-Zero Foam

What Is It:
Weapon MX tank G-Zero foam is a revolutionary new product on the market that has been proven as one of the best accessories to improve handling and track performance in a variety of off-road vehicles.  Weapon MX tank G-Zero foam is reticulated polyurethane foam. This foam is new on the motorsports market, but is not a new invention.  It is military spec foam that has been put through rigorous testing and been proven to be of such high grade that it is used in all government fighter jets and tanks.  The foam is also so porous that it only takes 2-3% of the volume of the tank and also has a 30 year lifetime.

Installation:
Installation was a snap. Make sure to clean the area around the gas tank so nothing accidentally falls into your tank. Then you simply compress one end of the foam and start filling your tank. (Clean a T-handle with some contact cleaner and use it to move the foam around inside the tank) The foam comes in small rectangles and stack like building blocks inside your tank.

Compressing one end allows you to fill the tank with G-Zero foam.

Ride Review:
Prior to installation I filled the tank up halfway (as Weapon MX recommends). I then took the bike out and rode a Moto. This is done to provide a baseline with which to compare the Weapon MX foam filled tanks. After the Moto I installed the foam and rode another Moto. The track I was riding had a lot of elevation changes so I noticed right away that the bike felt more solid and grounded. What I mean by that is that the bike was more responsive, and easier to control in the corners. The feeling of a lower center of gravity and improved handling is what Weapon MX claims, and it’s exactly what they deliver.

During high speed corning, gas does not slush around creating extra side-to-side forces.

Without the extra up and down force of 3-6 Ibs. of gas, one has better control entering and exiting the whoops.

Conclusion:
The key to G-Zero foam is its thousands of pores.  These pores are what eliminate the sudden and violent sloshing of fuel within the tank, most often felt in tight turns, breaking bumps and G-outs where your 3-6 lbs of fuel can feel more like 25-30 lbs of fuel sloshing from front to back and side to side.  We would recommend any racer pick up this very cost effective solution and end those extra forces associated with sloshing fuel.
