    by request Sigma Computer Mount


    here is the sigma computer itself mounted on the triple tree


    this is the sensor mounted on the left fork with some clever wire work it mounts. (the stock mounts are made for narrow bike forks so it was a no go)


    the magnet is mounted onto a ziptie which is then attached to the brake disc.

    the system is calibrated by taking the measurement of a full rotation of the tire, and entering it into the computer, it then counts the passes from the magnet and give an accurate reading...(supposedly more accurate than the stock speedometer)

    the previous owner did all of this but showed me how hed done it.

    any questions??? ill do my best to anwer them

      what model sigma is that? BC 506? I recently emailed a rep and he says that ALL sigma computers can be used for the motorcycles b/c they all accurately read up to 186 mph. However, I read a review from someone saying that his doesn't and he has the BC 1106 or whatever it is.

      Also, how far away from the sensor is the magnet? I hear it has to be within 5mm...

      Thx,

          I have a BC1400, I think.
          Works fine. I binned the supplied magnet with a sooper dooper one off eBay (20p each I think) that clings to a tiny steel bracket on one of the disc bolts.
          The display mounts to my Lobuc dash using the chopped Sigma mount and a single screw. You have to extend the wiring, that's the only other change I made, and no big deal really.

            Hmm, interesting. I've been looking for a digital clock for my dash area so think I might rig one of these up and the added speedo is a bonus..

              its the sigma bc1606L its backlit for those nights where i need to scope LEOS

              as for the magnet... i have it just barely set at about 2-3mm at speed though it makes a faint click. i noticed i dont hear it as much now that i have a whindshield pushing the air around my helmet
