On average from the last available fuel station around 40-50kms.
That's why I have the extra tanks on the HP2.
On my KTM, 28 liters are more than adequate, specially with the 650cc engine.
I'm in Cairo, Egypt.
This picture was taken somewhere in Europe, can't remember, maybe Germany. I was touring there.
This is my bike in native habitat...
This is my other bike (R12GS), also, in my backyard.. :biggrin:
