Titanium and Speedo sensor

[He Man]

if you used titanium rotor bolts would the speedo not work on the newer speedo drives that are mounted at the rear?

I helped someone install Ti bolts and nuts on his new wave rotor. He took it apart and i wasnt watching so either I put it back wrong, or Ti bolts dont trigger the speedo...

Civil Engineering.

Ok, so now i know how it works. Does Ti make a magnetic field when it spins?


edit: verified Ti will not trip the Halls effect Sensor.

Next time you feel like lecturing me about metallurgy and corrosion...

save it.

I don't think titanium is magnetic, but your problem is that the new wave rotor don't have the iron pigs that triggers the speed sensor.

Im the young pretty one here. ducpainters going to have to woo me slowly ( im not looking for a 1 night stand though).

on a serious note though. for future reference. keywords Titanium Sensor Speedometer Halls effect

1) You cant turn Titanium into a permanent magnet.
2) the halls effect sensor on our bikes generates its own magnetic field
3) it detects other fields that causes a change in its own field.
4) Iron and other iron based metals will generate their own magnetic field, the sensor detects this and gives a reading.
5) There are no "iron pigs" on the wave rotors ( i havent inspected the stock rear rotor enough to know what your talking anyway) but they have no effect on the speedo sensor.

Result: Absolutely no reading with Ti Bolts. Replaced Ti Bolts with OEM Steel bolts, sensor works again.

If you wanted Ti Bolts to work with the sensor then either you dont need your speedo, or you need to find some way to get the Titanium to make its own field. Which is more work. Maybe those "iron pigs" on the rotor help give the sensor a clearer reading and if you use a stock rotor. Not sure on that though.

Comment: Dont waste your money on Titanium unless u got the dough son!

agreeeeeee!!!

this experience results in 6 M8 bolts hanging around.
see if there's other places I can apply ....

so make every other bolt titanium and whatever the speedo says, just multiply by x 2

Sorry for the bad spelling in my post, I do mean pegs not pigs.
The only reason they are there is for triggering the sensor.

that makes the most sense out of everything else on this site.
