I just filled up today not a few moments after the guage began to blink. I fill up just to the inside rim. It only took 3.6 gallons. I will post my findings later next week. Also, you should probably post your weight and riding style. I weigh 230lb and ride agressive most of the time. I downshift more than I use my break also. So my mileage will be less than some.

 

i ask this ? bc i was getting around 45 mpg too. and my friend gets 70. although he rides a yzf 600r.
