Set the speedometer to 17" rims?

Hello! I have supermoto rims on my te 450, the speedometer shows wrong with atleast 20km/h. Is it programmable?

I hope someone corrects me, but on the 250/450/510 I believe the speedometer is initialized at first power-up to one setting and it can never be changed after that.

The dealer told me the same thing when he delivered my new speedo on Friday

I have heard their is something you can do...?

Ive pissed around for a fair while trying to get it to change. you cant unless you start trying to see if you can short out one of the IC's in the speedo. I'm an electronics tech and could be bothered. The only thing you can change is miles to kms i think.

Easiest way to get past it is to grab a GPS and check you speedo against it at varying speeds. You should find something like this.
All in kms
72 bike = 60 real
84 bike = 70 real
96 = 80
108 = 90
120 = 100

Also start logging you services in excel so you can account for the extra kms that will appear on your speedo.
