Has anyone gotten a straight answer about the optimistic speedometers? Mine is off over 20 % on the US model 1290.

Been told by my KTM dealer it is within the Australian ADR guide lines so live with it. I have got used to looking at my second Speedo which is set just under my GPS speed & ignore the main Speedo.

I'm having the same problem right now. Good thing I read this thread its really helpful would try to talk to my dealer and claim it from the warranty.

i checked mine by using my gps and
at steady speeds was high by 10%
dealer told ktm they as to date have no
answer

Mine speedo reads 10% faster than the GPS also!

I just figured out how to use my Garmin to record trip distance.

On my bike the odometer, on one 42 mile trip, recorded 3.7% more miles than the GPS.

Love the bike but feeling serious contempt for the KTM customer service arm!

One month after starting to make calls to the KTM USA Customer Service phone number ((440) 985-3553) I still have to get a reply.

I especially like this on KTM US's web site, "Phone calls made to the Customer Service line may be monitored and recorded for quality assurance purposes "

Quality Assurance my ass! I've never had one of my calls to them answered! Not one! The voice mail thing throws you into unanswered loops punctuated by annoying beeping, offers to go back to the main menu which puts you back into the same loop and then, finally, dumps you into the answering machine.

Sounds like a good way of getting out of a speeding ticket to me.

By the very fact you know it under reads so you have to go faster than the designated limit on the speedo to keep up with traffic and visa versa if it under read.

I dont know how they legally get away with having a speedo so far off.
