I know that a lot of you don't care about the fuel economy of your bikes, but I am curious to hear how it is affected by an ECM and aftermarket pipe. Over 5,000 miles last year my '08 averaged 34 MPG. So far this year I have averaged 35 MPG over about 700 miles. My bike is still 100% stock. | ||

I have about 7500 miles with Erik Buell Racing ECM and HMF pipe, and I get 33 MPG no matter how I ride. | ||
| Froggy |
My best was 55mpg average with the Race ECM and 48mpg stock on my 08. I've seen a good 10% increase in fuel economy on all my Buells that I've put a race ECM on. | ||

Before the ECM I got about 38. Now I get 35. | ||
| Eddie |
My average is 44mpg with a Barker exhaust and Eric Buell ECM. | ||
| Mountainstorm |
I get an average of 36 with the Erik Buell Racing Race ECM and Barker and I like twisting the throttle. | ||

Wow, why am I getting half the mileage of everybody? I'm usually around 22-24, but I actually hit 19 the other day. I even ride like a sissy, but I do let it warm up for a while before I ride. | ||

It's safe to ignore Froggy's numbers... his numbers are due to a "unique" riding style. :-P I lost a few mpg with the race ECU - somewhere in the 2-4mpg range, but it's hard to tell at this point since my riding varies more than it used to. //EDIT: I'm getting around 38-41 now with the race ECU, I think I was getting around 43 with the stocker. However, I was still fairly new to the 1125 & wasn't opening it up as much when I had the stock ECU. (Message edited by Syonyk on May 12, 2011) | ||

My MPG stayed about the same. About 34-35 mpg normal riding, down to 24ish when having some fun... | ||

26.6k on Loretta now - OEM ECU consistently showed 39 on AVG MPG. Erik Buell Racing ECM for "open intake/exhaust, pump gas" is steady at 38 MPG. I will be sending the ECM back to be flashed for the Drummer I run, after Erik Buell Racing gets back to doing parts.... Zack | ||

My race bike says i'm getting 22mpg. All track miles. | ||
| Xtreme6669 |
Just looked at mine... 31mpg. I think I was at with my O S B tune and don't remember what stock was... I don't commute much on mine so its all fun riding and most is aggressive. | ||

I can't seem to stay out of the throttle. I averaged 30-35 mpg depending on if it was a "commute" tank or a "fun" tank of fuel. After the race ECM it dropped 1-2 mpg for each ... 28-33 mpg. | ||

i track the mileage every fill up, calculated my self not what the bikes ecm displays. last 4 fill ups stock 31.1 34.9 33.4 31.7 last 4 with exhaust and ecm 37.9 38.0 34.4 went to the drag strip 39.3 i was very impressed how much mileage improved | ||

You guys are looking at it all wrong! It's SMILES per gallon, not MILES. | ||
| Smit3833 |
I was getting around 36 commuting stock. Now with the Erik Buell Racing ECM and Keda RT-4 I get between 33-35mpg, but I lay into the throttle whenever I get the chance and cruise around ~90mph on the freeway. | ||
| D_adams |
I also see about 38-40 mpg cruising @ 70 mph. Stays pretty consistent across all the pipes I build. | ||

No offense Froggy, but I would have to see you achieve those numbers with my own eyes to believe them. Of course not knowing the number of miles included in those averages makes them somewhat meaningless. If I took her up to 160, tucked, pulled in the clutch, reset the average, and coasted down to 55, I bet I could push triple digits on that average. That is, unless you are riding on two inch wide solid rubber tires. I have had to deal with some highway construction zone speeds on my daily commute, and I am convinced that if all of my riding was fuel optimized by riding around 55 MPH, the best I could average is about 55 MPG. And yes I certainly get the SPG vs MPG comment, but when gas is $4+ per gallon and range is a consideration on your weekly commute, MPG does mean something. I find it interesting that different rider's results vary so much on whether or not it increased or decreased fuel consumption. | ||

the computer tells me 35mpg average. when i look at the instant it usually tells me about 40-48mpg. i road 57miles non-stop yesterday gas station to gas station about half on superslab no less than 75mph usually 85ish then 2 lane that i averaged about 60mph on. i don't do much city stop and go anymore due to my work schedule the afternoon is usually the only time i have slow and go on the way home in the heat. the 57 miles yesterday cost me 1.4gal which worked out to just at 40mpg. | ||

Clk92vette: He does them. Regularly. Over long, long distances. Pretty standard hypermiling with some slightly questionable tactics will get you there. The bike uses a ton more fuel on engine braking with the ECU than it does at idle, among other things. And I can think of plenty of ways to push efficiency up if I cared. Also, inflation pressure of the tires matters. IIRC Froggy runs on the high side, and I wouldn't be surprised if he runs a bit over the max suggested pressures. | ||

Clk92vette, I have detailed logs of every tank of gas I've ever had. I don't rely on the dash. I can do 220 miles without even seeing the gas light even flicker. Here is some photos, but like anything else it isn't hard to cheat so you are going to have to take my word for it.   224.1 miles on 4.08 gallons of gas is 54.92mpg I got similar but not as good numbers on my CR, and my XB has done 75mpg, my Blast is my champ at just under 85mpg. I am a hyper miler, some people try to maximize speed, some try to get the fastest lap times, I try to get the best fuel economy and tire life possible. Fuel economy and tire life go hand in hand, I get 80% better fuel economy and 80% better tire life than the average rider. | ||

Froggy Shutting the bike off and coasting down hills isnt how "most" people calculate their MPG. I ride in 3rd gear 6k rpm and my commute is 25 miles 1 way or 50 miles a day. I can go to work and home twice but the ride home will be with the fuel light on and im nursing every mpg out of it. So 200 miles a tank and between 35-40 mpg | ||

Froggy always rides down hill like UPS drivers turning right all the time | ||
| Zac4mac |
One of Froggy's secrets is high tire pressure. Downside is a smaller contact patch. I did 2 "Parade Laps" at Road America in 2008 and forgot to drop my tire pressure. I saw 104mph at one point and several times my bar-ends were "inches" from the ground. The OEM Pirellis are very sticky when warm. I saw a 7mpg drop, going from 42psi to 39psi on my front tire. Want better mileage? pump up your tires. They still stick fine when WARM. YMMV Zack | ||

I too was a sceptic about Froggys #s but Ive tried a few of his hypermile tricks and have achieved 50+mpg on several tanks. It does work and its drastic on the 1125s. I have no doubt that an experienced hypermiler like Froggy could achive more. Its so hard to be that disciplined though. I do a mixture and can easily average 44mpg. BTW, I do have an Erik Buell Racing ecm and Keda RT1. | ||

My millage went to s*** when I get here to Germany. Course, that might be because of my getting heavy handed on the Autobahn. | ||

With E B R ECM, stock everything else: 33 mpg road 23 mpg track Can I justify a slip on with the projected gas savings from an extra 5 mpg? Since this is numbers not riding thread, let's do the math: A 15% increase in fuel economy @ $6 per gal = $.90 saving per 38 miles. Therefore I will recover my $600 slip on purchase in 1000 gallons or 38,000 miles. I only ride 6,000 miles/year (short season here) so return on investment comes in 6 years assuming a steady gas price over the term. | ||
| Clk92vette |
Froggy: I can appreciate the effort you are putting forth and your subsequent results. If my selection criteria when I purchased my 1125R was minimizing fuel consumption I would have bought a Brammo Empulse: http://brammo.com/brammogallery_empulse/ But to each their own! | ||

Geezuz, you must drive like a little old lady!  224.1 miles on 4.08 gallons of gas is 54.92mpg | ||
| Tpoppa |
If you want to hypermile...the 1125 seems like the worst possible choice of motorcycle  Doesn't just about any other motorcycle get better mileage than a high hp v-twin? |
