Well i for one would rater fill up a bit more often than haul 30 kilos of fuel around
Modern world plenty of fuel stations you just don't need the range
30 kilos is about 40 liters. most bikes take about 17 - 21 liters. A air cooled 1200 gsa will hold 36 liters (they state 33) So thats a 14 liter difference about 10 kilos. Personally I never feel any difference between empty and full. Mabey thats because I weigh 120 kilos dressed in my bike gear. I perefer to have the range. I fill up every 5 days. A standard gs would do me 3 days. Thats only comuteing. JJH
