    Speedo change from kilometers to miles

    I live in the States and just bought a formerly Canadian 2003 Rockster, so it reads kilometers on the speedo and odometer. If I buy a used speedo, can I simply remove one and plug in the other successfully? Will I need to change out the gearing to make it accurate? Will the canbus freak out?

    Thanks for any help you might be able to provide!

    Best check with the dealer.

    Canbus was introduced on the 1200's

    I am assuming that all 1150's had mechanical speedometers. I know my 04R1150RT does. It drives off of the front wheel.
    2004 R1150RT 145,700 miles
    1991 K100LT 126,700 miles
    1982 R100RT 106,900 miles
    Total 379,300 BMW miles

    Not all, check the MAX fiche. There is no Speedo Hub or cable listed for the Rockster

    Thank you. So this is an electronic speedo? It would make some sense to me for it to run off of the ABS sensor if that is the case.

    If that is the case, would the same electronic input from the bike work on a US model mile calibrated speedo versus the Canadian KM calibrated speedo currently on it?

    Thank you all for your help!

    According to the fiche, the Rockster uses the same speedo drive as the 11S. Electronic pickup, located in the FD unit. Near, but not same as, the ABS sensor.

    So if you want to swap out for a "miles" unit, i would look for a speedo taken off a US model Rockster.
    I think the conversion issue that will get in the way of easy adaptability is the Odo, not the speedo (that could likely be fixed with a new dial face, or mph notations on your original). Personally, i would just make marks on speedo indicating 5 or 10 mph increments for dealing with speed limits and such, and not worry about the odo reading- just do the math, if necessary.
