In the last 11,000 miles that I rode for a total of 16,000 miles, I averaged 69.58 MPG I could easily average over 70 out on the country roads or in the mountains (Over 75 above 5000'). On the freeway cruising 65-70, the mileage would drop to about 65 mpg. 2011 G5 with 18T sprocket, EFI Exhaust, K&N Filter.
