Won't be riding again for a few days due to weather rolling through, but I'll start doing that! My averages are usually mid 50's.
The thing about motorcycle fuel economy though, it's SO independent. Motorcycle are affected by so many variables at some amplified levels compared to cars. For example, in a 4-door sedan, your gas mileage is gonna be the same whether you weight 95 pounds, or way 295 pounds. I've talked to guys who own 900's who barely break 40mpg, I myself get closer to 60, I once talked to a guy who had a tank average 74mpg!! It really depends on you, your riding style, and what you've got on your bike.
What I've learned about the fuel economy on the 900:
Speed is a big factor. The way the 900 is geared, it seems to be geared for 60mph in 5th gear is it's 'sweet spot', so speeds over that are revving ABOVE the 'sweet spot', not to the point of over-revving or anything like that, but it does start to run a little quicker than a lazy thump. The most efficient the bike runs is probably in the 40~55mph range (which is the way most cars are actually- there have been a lot of lab test of fuel use and the vast majority of vehicles had the best fuel mileage running around 40mph, wind resistance is a big deal) It starts to get ALOT worse about 65mph. For example, I rode a 4 hour trip down to southwest, MO a while back, 2 up, averaging about 50~52mpg running 65mph the whole way. On the way back, it got ALOT colder than predicted, and I was getting COLD. I ran it at about 75 on the way home, sometimes closer to 80, when I got gas halfway I was only averaging 39mpg. Makes a BIG difference! So if you are wanting to save gas, take the 55mph state highways, or run 65 on the interstate where it's safe to do so (Sometimes it's not in those big city areas, you'll get run over...)
I lose a couple miles per gallon when I have the windshield and lowers on, it's a lot more wind resistance. But, even in the summer I ride with them. I don't like the pressure on my chest and it makes my riding jacket ride up, I don't mind the extra gallon of gas per week or whatever. Two up cuts into it too but my passenger doesn't weight much at all, I think it has more to do with the fact that she sits up above me a little, again, adding to the drag. Talk to sportbike guys, those Ninja 250's are known to get 100mpg when the riders go easy on them and tuck in, wind resistance is everything!
acceleration makes a big difference too. Seems like once that engine hits 4k RPM's or so it starts to suck that gas hard. Shifting early and accelerating slowly (where practical and safe) seem to bump it up closer to 60. I usually get right at 62 commuting 1 up on a 55mph road that's a little hilly, but not bad. I shift early, accelerate probably just as fast as I do in my car but not any faster (unless there are cars behind me), and don't go above 55. Last summer I ran it without the windshield (I didn't have the lowers yet and the buffeting was killing me) and had a couple tanks averaging 65.
Finally, the biggest thing I learned about motorcycle fuel economy on my new bike: It doesn't matter! haha!
Okay, sort of kidding, but I have to admit, when I first bought the bike my thoughts were "Oh great, good gas mileage, I can save some money on my commute". While that's true, once I throw my leg over it, fuel economy is the last thing on my mind. I ride easy and sensibly because that's safer and that's what I prefer anyway, BUT, I gotta tell ya, once I fire her up, I could care less if she was getting 12mpg. Originally I was steered away from a bigger bike because of fuel mileage, but I'm starting to think that doesn't matter to me anymore. (Although I still don't think I'll go with a bigger bike, m '9 has yet to feel small to me! It's nimble and handles everything I throw at it, of course, I'm content to glide along at 65 so, I'm easier to please than most)
