[QUOTE="TMack"] Does anyone know which bike has the greatest range (distance between required refuelling stops) under fairly normal driving conditions? It has to be a trade-off between tank capacity and mpg so any guesses what is likely to return best average figures?[/QUOTE] You're in a class of two, really. Honda ST1100 Pan European or a BMW GS with the optional 30-litre tank (and even then, Big Tony managed to run out). Both will manage 250+ miles. Can't think of anything else, off-hand.
