yes but that is not legal.
manufacturers are entitled to a 10% tolerance in speedometer accuracy "the optimist way"

having a speedometer indicating a lower speed than then actual speed is illegal.

the speed displayed by your speedo can legally be up to 10% higher than your actual speed, never lower.

Hiya,

That was not my point lol. I understand what you write but the logic of the OP is perhaps odd? Better be legal at 25MPH and show on the clock 30MPH. This gives one a decent safety margin. If you see 70MPH you KNOW you are safe as you are, in reality, doing 65MPH thus not going to get a ticket.

Best,

I wondered why my new Ten seemed to feel so slow at an indicated 30mph...
+1 for using a cycle speedo as a cheap and easy way to check accuracy. Once you know the variation, much cheaper than a speedo healer is a simple mental calculation, which has the added advantage of avoiding disrupting the odometer reading.

Mine's +10% all the time - easy maths to do on the go and my sat nav' (if fitted) is there too..

Speedo Healer ODO error
 

Hi all,
I recently fitted a speedo healer to the XTZ, I have the speedo now reading +2kmph over the indicated GPS speed at 120 kmph,
One thing I have noticed is that the odometer is way out, approximately 6km in 100 too low,
GPS indicates 100 km distance and the odometer reads 94km.
Not really a problem, but I now have to work out the fuel range indicated in comparison to actual distance required between fuel stops.

i have heard that it remains at the old setting even if you fit a healer. very strange as i would have thought it would be adjusted along with the speed reading. bit daft in a bike designed for the dirt.... it should drive off the front wheel as per the ktm's

Speedo Healer for the Tenere
 

Hi,

Just gone to 14/48 gearing on the T�n�r� and of course the readings are a mile out.

Measured against a Garmin Zumo (EGNOS on) I'm getting 30mph (GPS) against 36 indicated on the Z's clock and 15.7 miles (distance on GPS) is coming up as 17.7 miles on the clock. Bike has TKC80's fitted, std 17" rear rim.

I'm ready to fit the SpeedoHealer but I'm wondering what I'm trying to fix, the over-reading speedo or over-reading odometer. I think I'm more fussed about the odometer being accurate as I can get an accurate enough speed from the Zumo.

So, daft question, do I set the Healer to the %'age the odometer is out?

Thanks.

the photo's on page 1 don't work anymore. can anyone upload them again please?

Impossible to get the photos back on the forum as they are remotely hosted by Ray, they're only links to them on the forum, and he's obviously removed the hosted images.

However, all is not lost because I happened to have the foresight to make a copy a few years back of most of what was in post #1, including the photos! I have attached it for you.

Thank you :smilies0346:
