Many riders insist that tanks are too small on modern motorcycles, but the real story is far more nuanced than a simple glance at fuel capacity suggests. In this episode of Throttle and Roast, host Niels Meersschaert digs into the full picture of motorcycle range, examining why manufacturers build smaller tanks, how fuel economy changes everything, and whether the complaints flooding social media actually hold up in the real world. Niels begins by establishing the extremes of tank capacity currently available on the market. The smallest street motorcycle tank belongs to the Honda Grom at just 1.6 gallons, while the largest is found on the BMW R1300 GS Adventure at 7.9 gallons. Most of the bikes people complain about fall somewhere in between those two extremes. Manufacturers choose smaller tanks for two primary reasons: aesthetics and weight. A larger tank dramatically changes the visual profile of a motorcycle, and with fuel weighing roughly six pounds per gallon, a fully loaded large tank can add nearly 50 pounds of weight concentrated high on the bike, affecting low-speed handling and overall feel. As modern bikes have also added electronics, ABS, TFT displays, and other features that riders demand, manufacturers have had to find weight savings somewhere, and the fuel tank is often the easiest place to trim. But tank size alone does not tell the full story. When you factor in fuel economy, the range equation shifts considerably. The Honda Grom, despite its tiny 1.6-gallon tank, achieves around 125 miles per gallon in real-world use according to the fuel tracking tool Fuelly, giving it a range of roughly 200 to 250 miles. Meanwhile, the BMW R1300 GSA, with its nearly 8-gallon tank, returns around 40 to 44 miles per gallon in practice, translating to 315 to 395 miles of range. That is a meaningful difference, but far less dramatic than the raw tank size comparison would suggest. Niels backs this up with over 15 years of personal fuel data tracked through Fuelly. His Vespa GTS 300, with a 2.2-gallon tank, averages 67.6 miles per gallon and delivers close to 150 miles of range, more than enough for his typical short errands. His BMW F900GS, despite having less than half the tank capacity of his old R1200 GSA, achieves nearly the same practical range thanks to better fuel economy on the newer, smaller engine. Even his BMW R18 Classic, a cruiser that many riders criticized for having a tank that is too small, delivers a Send us Fan Mail Support the show Thanks for listening!
