Here comes part 2. The original fuel tank is located in the rear, below the seat, and can take about 13 l. The auxiliary tank is where motorbikes usually have the fuel tank, and replaces the big KTM airbox, which was replaced with a smaller racing air filter. This gives me an additional 5 l of fuel, which can make a big difference in autonomy during extended offroad travels. You can see the black fuel hose running from the aluminum adapter, along the outside of the frame, before disappearing back into the frame. Sadly, there's no way to better hide the fuel line in this place.
Today's post will be a 2 part story. I added a Rade-Garage auxiliary tank to my bike. The fuel pump is removed from the tank, and an additional spacer with a fuel inlet is added between pump and original tank, allowing the pump to pull fuel from the aux tank as well. Removing the pump proved to be very messy, as you can't fully empty the tank.
