Odometer Inaccurate?

[DM]

I just came back from a little trip and my odometer appears to be off by about 3.54%. should I be concerned? can Yamaha fix it? I can deal with a speedometer error but I thought Odometers were supposed to be accurate.
My Example:
Odometer Reading: 3306.7 kms (2054.63 miles)
GPS Odometer: 3189.6 kms (1981.93 miles)
Should I worry?

When the speedometer is off the odometer will be off as well.
A Speedohealer is the only way to correct this that I know of .
I was able to correct FZ1 by changing drive sprockets but no
such luck with S10 .

All my bikes have been off by a little - not much you can do about it. Does the SpeedoHealer fix it?
otherwise -

I found mine showed only about 1-2% out, the speedo is about 7% out, I also wonder if the terrain can make a difference, the sat-nav will not take into account undulations and bumps the bike goes over, but this will increase the wheel travel - and therefore miles covered.

Not 100% certain how sat-navs deal with hills either :question:

Yeah, they are all a bit out - usually 2-4% over. The speedo is 7-8% over. If you use a speedo healer (great little device BUT there is no plug and play wiring loom for the S10 - they supply a "universal" loom that involves cutting into the original wiring loom - not good), and correct the 8% speedo error, your odometer will now be 4-6% under which has got you exactly nowhere. Just live with it.

I got 30.5 miles against 30 miles indicated by sign posts. This is within 2% (1.66%). I wouldn't trust a GPS any farther than I could throw an anvil, but don't get me started on GPS.

This wiki seems to indicate that Honda standards for cars is within 2.5%. I see test results on the web of 1 to 4% for various vehicles on a Google search. Given motorcycle tire differences, I would assume the tolerances would be wider on a bike.

No, No & No.

The SpeedoHealer can correct the speedo reading, but the odo will still be off. I don't off hand know if the SpeedoHealer alters the odo reading on this bike. (I do have the Speedohealer, just never bothered to check) I do know my odo is off still, even though my speedo is very close now.

Over a relatively short period of time on a straight road, I'd trust the GPS odometer to be reasonably accurate, but not for a long trip over twisty roads. A bunch of error factors start to come into play over long averaging periods.

I haven't done it, but sign posts on the interstate would be the best way to calibrate the odometer.

My speedometer was 8.5% optimistic and my odometer was about 3% over as compared to a gps. I corrected the speedometer reading with a speedohealer and now my odometer is 5.5% below actual mileage. I like my speedometer to be accurate and don't mind at all if the odometer shows less then actual mileage. Yamaha should have done a better job calibrating the speedometer and odometer.

See - exactly as I predicted. I suppose it does no harm to have less mileage showing when the time finally comes to sell!

Howdy,
Have not sat down and done the math but I have been using those unmanned radar signs that warn you about slowing down. My S10 shows about 4 mph slower on the radar than what the speedo shows. I take this into consideration when I'm pushing the limit, usually a cop will give you 5 mph plus the 4 mph so in a 35 mph zone I feel pretty safe with an indicated 40 to 44 mph on the speedo. The Tenere is not bad in this respect, just about everything I've owned has been off with the worst being my GL1800 which was somewhere around 6 mph +. I somewhat remember ( I am old) that someone wanted to launch a class action suit against Honda because the inaccurate speedo/odometer would have the bikes coming out of warranty sooner then they actually should have.

At 100 kph on the gps, my speedo reads 109kph. After 2 sets of Tourane EXPs I changed to anakee 2s last week and now at 100 kph on the gps, the speedo reads 106. I realize tyres will play a role, I can live with the difference and just use it to keep my license.

Well since you're old we'll give you a break, lol. He's complaining about his odometer, not his speedometer.

Howdy,
I do believe I mentined both the speedo and the odo. Unless I'm missing something I believe they are cosmically attached! )

Definitely. When I put the K60s on my bike the speedo became noticeably closer to the GPS.

My wife had new Anakees and I had a fresh K60 when we left for a 4,500 mile trip. There were several opportunities where she stayed back at the hotel and I went out for a ride during the trip. My best guess is I put an extra 75 miles on my bike during the trip. When I checked the odometers I was a little surprised to see:
Her bike: 4556
My bike: 4515
GPS: 4480

Was that the tires, or a different error built into each odometer? Don't know.

You THOUGHT she stayed back at the hotel! People pay private eyes for evidence like that. Only joking but then again........

Hummmm...I see you're the suspicious type...that's good. But you never considered if I rode all those miles backwards to keep the mileage off the bike's odometer. Now who should be under suspicion?
