    The initial poster was talking about gas mileage. I was responding to how another poster assumed that people used motorcycles as, perhaps, a toy, or hobby. While that may be true for most, that's not why the rest of the world uses motorcycles.

    But, all for all: yes, it's not cheap to own and maintain a modern BMW, especially as compared to my old airhead. However, for bang for the buck, and the fact that I can commute all year 'round here in Virginia, then it is a very useful tool and, over time, it works out. My last beemer, a CLC clocked 86,000 miles, of which about 80,000 miles was commuting, before it got totalled in a rear-end collision. While the RT or CLC probably is not considered a commuter, they have served well in this capacity.
    Makes sense

    From the looks of things we are getting to an absolutist point in the discussion.

    I have the day off from my bricks and mortar job. I am working with some clients on the freelance side of my work life by telecommuting. Don't need no stinking wheels of any kind just slippers comfortable cloths, coffee and a decent internet connection. Nice because there is around 4" of new wet snow outside.

    I have yet to see one of these threads convince me one way or the other about the commuting, motorcycle mileage being good or bad and all the rest. However, I do find how you come to your brilliant conclusions worth the price of admission.


    Have to go put on a shirt, tie and jacket. Skype conference call with a client at 1:30 Fly-Over-Land time.

    "I can see the road better in rain" -- give me a break.

    However, it's true. On my RT, in heavy rain, most of it goes over the top of my helmet. The cars can't see and poke along. I just move out ahead, with a pretty darn good clear view of the road.

    That's my experience. Think what you like...

    I've commuted so long on the bike...it started out with being a single income family up in Detroit. Every March or April, depending on the weather, I'd flip the car keys to my wife and tell her the car was hers until Thanksgiving. That was about the extent of the mc commuting window in Detroit. My commute has always been about 70 miles round trip. Fun? Somewhat. Scary? You betcha, depending on the traffic conditions. Exciting? Always! Now, in Virginia, I am blessed with the fact that it really doesn't get that cold compared to up North. My commute is still aprox. 70 miles. It's a nice ride. The bike gets warmed up, fairly. I do, and have always loved riding in the rain. Gotta have good tires, though, of course. No offense taken at any comments, just pointing out that we ride for different reasons. Mostly, I just park the bike on the weekends - always have. So, ultimately, the bike is a tool, and I choose to ride, what I believe, are dependable and technically advanced BMW's. And, certainly - to each their own riding - may you enjoy it however you do it.

    I am an attorney. I ride quite a bit when heading to file stuff at the main courthouse simply because it is fun, and much, much easier to find parking. In fact, I usually park under a large oak tree directly behind the courthouse buildings, to the chagrin of my fellow attorneys

    More to the point, I am generating billable hours riding around on my Beemer

    Zipping to work in the car pool lane of a Los Angeles freeway on my bike is infinitely more fun than sitting in my cage, stopped, watching the other bikes go by. And since I don't have much weekend time for rides, it is often the only riding time I get.

    If that's the case, your ignition timing is way, way off. Octane is a measure of uniformity in combustion speed, not energy content. All gasoline has similar energy content regardless of octane rating. Too low of octane will cause knock, but only minor variations in efficiency.

    So driving around on "lower than supposed to use" octane fuel does not retard ignition timing? What I think my increased mpg with 93 RON fuel shows is an engine running at efficiency. You can't make a 122 HP 1200 engine efficient with 91 RON fuel. The damn ring on my fuel cap calls for 93 RON and I cannot get it here.

    You may have forgotten I have a different version of engine then most 1200's here. I know the HP2 Sport gets much better fuel economy on 93 as well.

Of course many smaller and even the giant KLT get a lot better, but com'on BMW, step up and make something happen again!!! That X5 sled gets almost identical as my GSA????? Bad picture in my book. Many are talking now, even VW's are on top of the world regarding this. I WANT BMWMC to step UP to the plate and make a FULL SIZE bike with the same spunk as the VWs and BMW SUVs,etc...My GSA1200 should be at least ahead of the above heavy vehicles! The smaller 650-800BMWMCs do get a lot better, but why not a 1200, if the cages are doing it???Randy
    I agree with Polarbear 100 percent. If I could purchase a high MPG bike I would seriously consider it. I have been looking at diesel MCs that get as much as 140 MPG. I would probably buy one if they were made by a major manufacturer and sold at a reliable dealership.

    We have one and luckily we have 93...even though most places has corn syrup in it. I tried to run 89 the other day as they were out of Super...it just didn't care for it on hard throttle roll on.

    Steve (henzilla) wait until you see how fast that fuel goes. An engine made to run on 93 burns 89 ugly and dumps it kinda fast, as well.

    I noticed...thought it was my spirited riding, but kinda figured it wasn't. The fuel icon came on really soon that afternoon.
    The K12S slurps it up as well...maybe 45MPG when at Warp 5. The 11S is prob the thriftiest at 49. 200 miles and you better have a plan on any of the S's.

    My GSA averages 39, but I have 9 gallons to manage.

    The energy content impact of ethanol dilution (<10%) is well within your uncertainty of measuring mpg for a consistent set of conditions.

    Are you saying that it can't be measured?
