More speedo bummers! SORTED!

So I've ridden about 60 miles round the backroads over the last few weeks with the new rev counter/speedo I fitted but it just goes to show how little I look at the actual speed numbers because yesterday going up to london on the motorway I see that I'm doing 130mph without even trying! I check it out because there's no way I'm going that fast and realise that the speedo is incorrect.

Now I know what you're thinking - that I've got it calibrated to kph but that's not it. I had to change that when I first fitted it and the speedo shows in mph and so does the odometer which was factory preset to 20,000 miles. The difference in speed and what showed wasn't the same ratio as mph/kph either. It was some random weirdness.

I ring Jim Aim KTM and explain the problem and they ask me what number is showing up at start up when you first turn on the ignition. Turns out my unit is showing the wrong number which means that it has been supplied by the factory with the wrong wheel size programmed into it. You can't adjust this without taking apart the unit and removing some of those wires so they have agreed that Jim Aim will do the recalibration on a warranty claim. Problem is they need the bike and it's a 200 mile round trip for me and they are booked up for 10 days anyway.

Bit pissed off because I have better things to do than ride there in this shitty weather over something that is KTMs fault to begin with. Mean while I have to ride about with my bike telling me I'm speeding all the time whilst racking up odometer mileage at twice the normal amount.

Damn Bic, hopefully they can get you a 1290 loaner or something. 100 miles each way isn't a paltry distance, I wonder if they had it programmed for a 690 or something.

Bic,
Have a look here

Very interesting mate.

The guy from Jim Aim said that he would have to take the unit apart and unsolder one of the connections on that multi-pin bank in order to recalibrate the thing. Looks like the wire snip is an alternative without taking the unit apart. Those off road boys sure know how to work stuff out don't they?

Don't know whether to have a go (and invalidate any warranty claims) or send the whole unit back by post and wait to get it all done for me. But this may take weeks to get back whilst being off the road.

Well. Some updated info on recalibrating the speedo on a Superduke.

I was so frustrated with the situation that I spent some time on the ADV forums last night reading everything that has ever been written on the recalibration issue. The ADV guys have it a lot because they are always changing their wheel sizes and having custom made ones and then swapping back to Supermoto mode with little wheels.

Turns out that the wire you have to cut is different colour depending on what model bike you have etc. The best bet is that my bike should have a Black/brown wire that needs cutting but there are reports of people also having everything go dead and to be very careful. Then I read a thread that was from a guy who claimed that the old 990 Supermotos didn't have to have a wire cut if they were pre '07.

So although my new unit is an '10+ model I thought I'd have a go. And I've done it!

What the programming through the buttons does is this....

When you turn the ignition on at first there is a flash up saying 'LENGTH' next to a number. This is actually the rolling diameter of the front wheel in mm.

If you put the mode button to show the odometer reading and hold down for more than 10 seconds it changes the setting from kph to mph.

But if you first use the mode button to change to Trip 1 and then hold the button down for 10 seconds it lets you change the Length number by individual digits. You do this with the reset and mode buttons to go up or down and then press them both together to save.

The correct number for a 17 inch wheel is 1870 which is written in the owners handbook.

I don't know if this trick will work for a post 2007 Superduke but it's worth trying if you ever get in this position. Saved me a lot of time and travelling and hassle.

What's weird is that neither Jim Aim or KTM head office knew this trick and wanted to start pulling the unit apart and snipping wires?? Good old forums And thanks to Dirty Irving for putting me onto this in the first place.

Good info. Glad you got it sorted.

I found this information under search" 1870"

Hi Robin,

Just press the mode button until it dosplays 'trip 1'
Then hold down the mode button (for at least than 10 secs) or until the display changes and shows length.
Now using the 'set' and 'mode' buttons, you should be able to toggle the length (diamerter) of the wheel back to 1870mm as the manual states.
Once you have the correct setting, press the 'mode' and 'set' buttons silmultaniously for at least 2 seconds to exit

Apparently under this same search parameter there was a posting that someone was looking to purchase a used motorcycle and stated that the mileage was 1870. I think maybe that that person was actually looking at the speedo screen while showing the start up wheel circumference number.
It has been many years since I read the owners manual, but from my foggy memory I seem to remember this adjustment process in the manual.
Speedometers and batteries, rectifiers and regulators, oil in water and water in oil, one would think that KTM could read this and learn a few lessons without dangling a dongle or snipping a wire to modify Italian muckery.
