I agree even with our wide open spaces in over 50 years of riding I have only had to carry spare fuel on a few occasions more as a precaution than a necessity ,even crossing the Nullarbor Plain it's now less than 200Ks between fuel stops , I crossed it in 1985 on a brand new Harley Superglide Shovel and carried 2 x 5 litre jerry cans 25 litres all up ,but sitting on 100Kph the Harley averaged 4.4 litres per 100ks over 60miles per Imp gallon
still got the Harley in the shed and will never sell it ,too many good memories
