I've managed to put over 150 miles on the Grom. I didn't pay attention the first time I gassed up. This time I managed to figure out my MPG. Put 0.63 of a gallon (89octane ethanol free), and rode 59.1 miles. MPG came out to 93.8 miles to 0.63 gallons of gas. Based on my calculations, that's about 128-miles per gallon. Does that sound about right for a stock new Grom that's still not broken in?
