Rear Brake Disc Screws Titanium with magnetic Inlet

Hi everyone,

just want to share with you a solution for the ugly bolts on the rear brake disc. They have to be magnetic for the speedo to work properly. So titanium screws are not an option.

BUT with a magnet inlet they will do:



10 Euro/ bolt :-(

Enjoy!

I disagree, all you need is 1 magnetic bolt and https://www.healtech-electronics.com/

With a speedo healer or a MotoGadget instrument i agree...

but without all bolts have to be magnetic

As i use the AIM Dash, i can configure the speed sensor:

1. Number of pickups (screws) - now 6
2. Radius of the rear wheel

So i would be able to just use one of those, but with the original dash and no speedo healer i agree with poolagent.

Rear Brake Disc Screws Titanium with magnetic Inlet

Hello All

I bought the magnetic titanium bolts (X6) two years ago.

I did mount the titanium bolts this winter and did my first ride with the titanium bolts in the beginning of the spring this year.

I noticed that the speedometer did only show about half the speed that I actually was going.

And yes all 6 bolts was wit the magnetic inlay.

I did remove the titanium bolts again and then I did use the OEM brake disc bolts again for a while.

Then I did try to investigeate what did cause the misreading. The result is that 3 of the Bolts have the magnetic inlay mounted in the titanium bolt so that the magnetic field that is in the end of the titanium bolt is a magnetic North and the other 3 bolts have the magnetic inlay mounted so it creates a magnetic South.

In that way the mix of magnetic North AND South is interfering the signal that should trig the Hall-sensor.

All in all I bought 3 new bolts with the same polarity as 3 of the bolts I already had.

So now I have 6 bolts with the same polarity - and it works now!!!!!

So all in all make sure that the magnetic polarization is identical for all 6 bolts if you are going to buy the titanium bolts.

Ciaoooo
