I'm not sure my bike could get 53 mpg coasting with the engine off. The bike runs incredibly, I have dyno charts showing 75 Hp and 66 ft. lbs. of torque at the rear wheel and the AF nailed between 12 and 14. But, I only get about 35 mpg and maybe a little more if all highway fill up to fill up.
I also take into consideration that my odometer is 2% off showing slightly less miles than traveled. I add that 2% before calculating mileage. I think the best the bike got was 40-45 (all highway) when new before all the re-jetting, carb, and BB mods.
