Yes, there is a two-year warranty. Dealing with the vintage motorcycle crowd means dealing with a user group that is honest and forthright 99% of the time. If you tell us there is problem, we are going to believe you and do whatever it takes to make it right. If you contact us after your system has crept out of warranty, we’ll probably take care of it anyway. The Ninja components (tank and regulators) carry their own one year warranty.
