Want to ease that sloshy feeling when you have a full tank of gas? Actually, that sounds kind of weird, but anyway… EVO Tank Foam allows gas to flow through its pores while keeping it from sloshing to and fro with the movement of the bike. It contains thousands of pores which stabilize the fuel’s movement in the tank.  The foam is so porous it only takes up 1% of total tank volume. It really is quite noticeable.
