Speedometer reading off.

Indiepaul · Jun 21, 2013

Has anyone noticed that the speedometer reading is much faster than actual speed? I compared mine with my Garmin zumo 350. It's off between 7 to 9 kmph(to fast, ie bike says 125kmph but gps says 117kmh). I even went as far to test the garmin in both my wife's car and my car. It's bang on in the car, and the Strada is off considerably. I talked to the service rep about this, he says it's normal. What do you guys think?

Yes, most bikes are a little generous in the speedometer reading, but the Strada is off as much as 6 mph

According to the owners manual the system calculates the speed and ads 5%.
117*1.05=123. In your case it seems like 7%.

You can buy a Speedohealer to correct the problem.

I had one on my Multistrada 1100, and will now install it on the Hyperstrada.

Ah that explains it. I was running on the interstate and at 75 mph in a 70 I was being passed constantly. So I stepped it up to 80.

Good to know StephanR. I thought i read my manual thouroghly. Guess i
Missed that part.
Just checked out the speedo healer. Looks like it's going to be my next purchase.
Thanks guys.

does generous speedo affect consumption calculator? cause its always generous/err's to high side

HyperEA · Jun 21, 2013

Just to add gatdammit's question; How about total mileage of the bike ? Does the computer display different number than it records for fuel, trip, tot mileage?

jerdog53 · Jun 22, 2013

I have noticed it as well, as much as 8 mph at 80 miles an hour measured with my Garmin Montana

For sure it is going to mess up things like fuel economy, total mileage,etc...
And eventualy it will have an effect on your resale value too!

Doubt that it will affect resale value at all.
Even if it was out buy 10% every 10k would only put 1K on total,
if i was buying a bike and one had 10k and another 11k then the price would be the same and the only factor would be the cleanest for me, so if the 11k bike was the best all round condition then thats what i would buy.

I believe the total miles are right, it's just the mph that are wrong.

doubt that, being a digital display

Yeah, the mileage is pretty close to right on, but the speed is at least 7% off. When you adjust it with the SpeedDRD it will probably take slightly less, maybe 6.5% then the odometer will be off that much the wrong way.

On my Super Tenere the Odometer was off 2% and the Speed was off little over 6%, so when I put the SpeedDRD on and set it to 6.1% the odometer was off the other way -4%.

I have installed the SpeedDRD on last couple of bikes, but think I will just run this one as is (HyperStrada), on trips I will have the GPS anyway, so I can always check that for legal speeds.

What is SpeedDVD?

Bingo!

I would rather keep the odometer correct, and compensate in my head the difference in the speedometer.

OK my wrong, but in this day and age of digital versus analog, if the odo is correct then I would have thought the speed to be correct too as they both use the same sensor do they not?? or is there two sensors??

Should have checked my notes, bad memory, it should be SpeedDRD, I corrected the above post.

They advertise as a plugin, but I have never had one even when stated for my model bike to plug in. Always have to find the wire and tap into it and get power someplace. Then you program it and test, then maybe fine tune it to what you want, I always settle on about 1 mph fast.

I am guessing there is just one sensor. Seeing as it is all digital, they can make the speedometer and odometer and any other function related to the sensor read whatever they want. They make the speed read high on purpose. Don't ask me why, but most motorcycles do.

SuperTen · Jun 24, 2013

Yep, they do it on purpose. Usually a blue wire coming from ABS to ECU is the speed sensor wire.

Cycle mags used to even have a heading in their stats column for bike tests named "speedometer error", or something to that effect. Bike gauges were always high.
