Honda NC750X 24lt Auxiliary Fuel Tank and Pannier Rack
I've had this on my 2015 S and my 2019 X and it gives an effective range of about 400 miles. It takes Givi monokey side cases. Connect direct to existing fuel tank breather outlet. You will need a Mocal or similar breather valve, an Aero style fuel cap and a standard motorbike petcock (fuel tap).
You still fill the main tank normally. The whole setup can be removed from your bike in under 10 minutes. I will post, and I will post internationally. Please message me if interested rather than comment here.
Thanks for reading this far?
