Side-Mount Rounded Aluminum Gas Tank for Mini Bikes
This side-mount mini bike gas tank pairs rounded aluminum end caps with a 4 x 12 in body for a clean, vintage profile. It holds about 0.6 gal — roughly 65% more than the FRP GMB100's stock tank (about 0.36 gal) — making it a good pick for longer rides and custom builds.

FAQ
Will this gas tank fit my FRP GMB100?
Yes. It works as a gas tank upgrade for the GMB100 series. Because it is a universal-style mini bike gas tank, plan on mounting straps or brackets (not included) and a fuel line run from the petcock to the carburetor.
How is this different from the 4 x 11 in cylinder gas tank?
This tank has rounded end caps, a slightly longer 4 x 12 in body and holds a little more fuel (about 0.6 gal vs. 0.53 gal). The FRP x JMCH Aluminum Cylinder Gas Tank has flat ends and comes in four colors.
