Post your BMW Airhead fuel economy
 
Been tracking fuel economy on the BMWMOA sight. People seem shy to respond. Thought I'd try to get a larger sample size here on ADV.

So post your BMW Airhead fuel economy and I'll keep updating the chart below. If you've already posted on BMWMOA, no need to post again. Should be good for all of us:

71 R75/5 LWB Just under 45 mpg at 60 mph.

Average per tank? It looks like people are reporting their best not their average. Mine varies from the low twenties to my record low forties depending on how I ride. Most of my tanks are in the high twenties but I usually get mid thirties on road trips. I normally cruise around 85 on the slab if I can get away with it. I cruise 100mph if everybody else is! I am sure I could get better but I can't stand to ride that slow. 60mph cruise? It would kill me for falling asleep! If I want economy, I will pick the right car. When I fall asleep, I might not get hurt as bad! :lol3

I was getting 45-48 average since before the build, about 35 after. Currently doing what I can to better that. If was like SS and getting in the 20s....I would be looking for another bike. I just got 30mpg and thought about it.....not acceptable mileage.

supershaft 06-18-2011 11:35 AM

It's not the bike. It's the rider. I could probably get mid forties if I slowed down. When I got my record 42mpg I was still speeding, just not nearly as much as I normlly do. :rofl

It's funny but here on the net most report mileage with airheads that most riders I hear of off the net weren't getting until they got a R1200.

Getting 35 to 40 depending on my right hand. I don't necessarily go fast but
I like to accelerate.

My R80 ST gets a fairly consistent 41-43 mpg when all is just right.

On the 1200 miles or so round trip to the ADV Spring Fling last month it was a consistent 41 mpg.

Thats a naked bike loaded for camping and don't forget that the ST final drive is a low low 37/11 which means conservative Interstate speeds are still spinning the motor between about 4700 - 5000 rpm.

I get pretty much the same results tooling around the Island here locally.

I'm surprised the traffic doesn't force you to do 85

zbg8000 06-18-2011 02:29 PM

about 34. Heavy throttle hand.

bikerfish 06-18-2011 02:44 PM

45+ on both my r100's, 78 /7 and a 93 r100r. I can squeeze 50 out of them if I want to.

Beater 06-18-2011 03:03 PM

I get about 38 per gallon, over the course of an entire tank. If it's all highway then a bit higher, but I really don't break the 40 barrier. PS - 1978 R100RS, faringless. All road.

To touch on what Stagehand said ... the RS minus the weight of the faring = BIG GET UP AND GO. I've beat a R1100RT off the line and ran with it even for 1/4 mile ... it had better top end.

So ... it depends on my right hand ... I do love the acceleration.

4ad 06-18-2011 03:07 PM

79RS euro (big valve, drilled box etc)...best I've gotten is 55 highway but usually 35-45 mixed

Well.....:D At times you really have no choice.
