speedometer error correction - Page 2

The speed-corrected white gauge faces on the Strom dress it up a bit too.

The guy was selling his stuff through either or both of the Strom forums - I don't know if he had other models in mind or not. The only drawback is that the backlighting isn't as uniform as the stock gauges at night, but I don't do much night driving, so no biggee.

[B]Ok guys, speedo healer people can make a fixer box for the BMW for 90-something euro (abt 140 -150 bucks). I guess nobody else has any better suggestion. I did notice the other day that an indicated 150 mph was only about 135. Seems like the error increases as you go up in mph.
I just dont understand why BMW does this. I have an 07 H-D Road King (believe it or not) and its speedo is almost dead-on accurate. My Guzzis are also MUCH closer in accuracy than the BMW. Come to think of it, my 1200GS is also inaccurate.

Can't comment on your accurate HD speedo, but most mfgs build-in optimistic speedos because by various national vehicle certification standards, it is illegal to build a speedo that reads too low. So to provide them a "fudge factor" to cover tolerances, different tire sizes, etc., they by design build them to read 5% high. So blame the safetycrats and lawyers.

Harley speedometers are dead right on.

So is my Porsche 928.

Don't know whats up with BMW.

my understanding is that the Odo is set for dead accurate while the speedo is always set 2-5% fast. the Odo remember must be set dead-on by law. I run a GPS verified speedohealer on the RC51 and it works very well - and has the additional advantage of retarding your odo (for that 1% higher resale value)!

The reason Harley speedo's are so accurate is the range they run in is so narrow you'd never notice the variance.....

Ahhh, another insecure person. Most people bashing HD are those that have never been on one and that like stereotype to feel "superior." At the risk of being seduced into diverting this thread into a tit-for-tat bash fest I have to say this :

I have several bikes, ranging from a CBR1000RR to a HD RK, several BMW's and other Euro bikes. Theyre all good in their own way. My riding style is pretty much sport-oriented although I do a lot of long distance and offroad adventure treks.

If you havent tried an HD in the last 10years or so, you may be surprised. They are not your curvey-road-go-fast bike but, even there, with the right rider, they will surprise you.

I rode the RK to the West Bend national rally and ended up completing a 5000+ mile trip through Canada. The bike was awesome. On the highway, cruising at 90 mph, it turns 3200 rpm. Thats amazing to me. The fit and finish on the HD is exemplary.

One thing I like is that I dont have to carry a backpack full of spare final drive parts in case my final drive fails as has happened on my BMW's. In my BMW riding group of 12 BMW's, 7 riders have incurred final drive failures. When I travel on one of my BMW's I routinely carry a seal/bearing set in case it happens again.

Back to the thread, I still dont know why BMW supplies such inaccurate speedo.

Can someone tell me where the speedometer sensor/piclup is located on the R1200S ??? and what color the wires are going to it ????

zimm · 12-25-2007, 09:21 AM

I did the speedohealer on my '98 Honda VTR1000. It works when you finally set it up. It's a slight pain the butt to set up at first- tiny micro switches and an LED are the interface. Once programmed, it works though. I got the remote recall button too which gives you top speed you attained. Really cool. I'd like to see what it takes to install on the BMW.

Maybe we should do a group buy?

While I had the speedo and headlight out to facilitate changing the horn to the Stebel tone, I took the time to print out another corrected speedo face. Wifey had a GREAT idea, we took the paper to OfficeMax and had is laminated. Now it lays very flat. I thought about putting in the tick marks for kilometers, but then thought "fuggit, I'm not taking this baby to Canada any time soon".

leafman60 · 05-29-2012, 06:07 PM

Wow, I got to thinking about this issue during my recent trip. I just did a search and discovered this was my first post on this forum! Still no solution !??

Has anyone found a solution to the speedo error ?

Guest24 · 05-29-2012, 06:16 PM

A good GPS should do 'er, mate.

leafman60 · 05-29-2012, 06:22 PM

Oh sure. I have that. But I'd like to have my bike speedo working correctly. BMWs are notorious for this problem. For my G650, an industrious chap in Germany with a machine shop re-cut some sensor rings to correct the error. Works great.

Because it's required by European regulation.

It's called speedometer advance.

For one thing it compensates for fact that different tires ostensibly the same size aren't.

It's a super bad thing to have a speedo that reads slow, and it's pretty close to that with a dead-on speedo given variations noted.

BMW has produced service bulletins on this in the past essentially instructing dealers to explain to bike owners that it's simply the way it is. The bulletins also note that despite this, odometers are accurate.

leafman60 · 05-30-2012, 03:10 AM

That is BS, lol. You dont need a speedo 10 mph off the compensate for tires ! lololol Hey, also, I am not so sure the odometer is accurate. I ran a test on mine during my recent trip and, yes, the odometer registered more miles than it should have !

Bob K. · 05-30-2012, 04:06 AM

I've used Speedohealer on several bikes. It works great and you can even get the one that holds in memory your highest speed from last reset. Cool in a way.
Anyway, you can dial in your speedo spot on.

leafman60 · 05-30-2012, 04:53 AM

Yes, I am familar with it but will it work on a BMW with canbus ?

Guest24 · 05-30-2012, 05:02 AM

Since BMW speedometers always read faster than actual, I guess that means that you could run the bike out of warranty sooner than you actually do. Which also means that we don't get the gas mileage that we think we do.
