I have absolutely no idea how the fu%"& people are getting such shitty fuel economy, fuelly shows average fuel economy for AT/ATAS at 45mpg-US (5.2L/100km). i just got back from a ~2000km BC trip, of which ~1000km's was off-pavement and about ~300km's off-road. i was doing ~130km/hr, passing aggressively at ~160km/hr on the highways and on the dirt i spent at least a good 200km's in 1st gear....... huge elevation gains and drops, as high as 3,000m at some points, and as low as 600m at times, several times a day. i rode at what i would consider "aggressively", constantly rooster tailing the back end, constantly breaking traction, and enough wheelies that i lost count....... yet at the end of the trip, (GPS confirmed). 1988.2km's and filled a total of 84.223L------> 84.223L/19.882= 4.24L/100km (55.52mpg US). how is this possible? does the 40t rear really make that much of a difference? i dont think so. does hyper mileing a 1000cc bike really make that much of a difference? if so how does one explain me going 140km/hr and still getting less then 4L/100km's (60mpg US)??? even for our ~6,000km's trip to california, i was doing 140km/hr at times WITH panniers and almost 100lb's of gear and gas on the back of the bike. still averaged 3.9L/100km (60mpg US) for the whole trip, average speed on the highway was 120km/hr. also spent alot of time in stop and go city traffic. like yes, i would consider myself a hypermiler, as im always upshifting/short shifting. i speed up before a hill then scrub speed while ascending (as long as no traffic behind me), coast downhill if its steep enough, never lug the engine, i dont use the brake often as i just lean the bike right over to get through a corner. every car i drive/driven i get 20-30% better then the EPA sticker fuel rating. i run regular pump gas 87octane with that ethanol crap in it. i change my 10w30 oil exactly at 12,800km's as per manual, fuel injector cleaner every oil change, re-use/ clean the air filter every oil change, running manual recommended pressures of 33F/41R, and i dont idle the bike, i just start her up and gently go.
