What size tank kit do I need?

A REGULAR Motorcycle Tank Kit is generally sufficient for a tank of 20L volume. However some nominal 20L tanks have very ratios of surface area to volume – this is especially true of modern tanks with large internal humps or baffles when compare to simple vintage tank designs. It’s critical to have sufficient working volume of sealant to be able to coat the entire internal surface area of the tank and in case of any doubt, the LARGE Motorcycle Tank Kit (for tanks up to 45L) may be better suited, even for smaller tanks.
