The winter refurb and essential jobs are underway. Front calipers have been split and fitted with new seals (thanks KTM) and they already have nice shiny titanium or SS bolts. This now makes the disc bolts look shabby.

So Ive seen ss bolts for the rear disc on fleebay but i think I'm correct in thinking that these will not register on the speedo sensor. I presume its magnetic saucery. Correct?

Has anyone changed them for anything other than OEM bolts.

No problem with the front disc bolts, they can just be replaces with shiny ones of the same size and thread pitch. Correct?

For the front, bolts of the same thread pitch (M8 x 1.25) are needed. You could probably get away with stainless, but I've played safe and used steel. For the rear disc, they do need to be steel. Not sure if you could get away with just one steel, or whether that might only indicate a fraction of the true speed...

I have stainless on the front, and mild steel on the rear.

yes that's what I thought. Just cleaned up the old rear bolts and they look ok now.
