    Speedo Accuracy?

    How accurate is the speedo of the TT?  On my old Honda it was off by as much as 6mph (i.e., when it said I was going 75mph, I was actually going 69mph).  I have not had a chance to pace myself against someone going a known speed so I got to wondering about the accuracy of my new bike.  :187:

    Mine is off between 3 and 4 mph. I would love to be able to change the digital calibration on it to get it accurate. How hard could that be? DealerTool guys, are you listening?

    Mine is also off by 3 to 4 MPH. I've never had a bike that wasn't off by 3 to 5 MPH, it has to be intentional by the manufacturers, but I don't know why.

    Yes... This topic been raised a few times in the past.

    As with most vehicle speedos the TT speedo overheads by 3-5  mph at 70 mph.

    The key is don't worry about it, accept it.

    That is pretty much what I expected.  Amazing how they can build this wonderful high tech bike but cannot make a speedometer that is accurate!  I am guessing it is due to some fear about liability from speeding though I can't imagine how showing the rider the correct speed would generate extra liability.  Interesting.  :084:

    Oh, and sorry for rehashing an old topic.  I should of just done a quick search.  I can see that this has been well discussed in the past.

    According to my gps mine is off by 4 mph at an indicated 80, and off by 5 mph at an indicated 120 (but don't let my wife know because that isn't close to redline in 6th).  Haven't had the inclination to look above that.

    It's off by about 5%, which I find infuriating, considering all of my automobiles are either 100% accurate (ex-police car) or off by a linear amount (1mph). One of my Honda bikes is off by 1mph, and the other is off by the same 5%. All of these have been speed-checked by RADAR.
