Custom modified OEM Honda fuel tanks built to hold apporximately an extra gallon of fuel. All tanks are Tig welded using a  customer supplied tank. That means you will be required to send in your tank to be built. Average turnaround time for tank fabrication is roughly 1 week from when we recieve your tank. Tank builds are currently only offered for the SF grom (2017-2020). These are a must when running a 250/300 swap or a preformace motor!
