Rear brake Disc Bolts?

Percymama · May 2, 2016

Hi Guys

Can anyone confirm the size of the rear brake disc bolts for a 2008 Gen 2 Tuono? (and the Banjo bolt if poss)

Need to replace mine for High Tensity Stainless Steel as they are rusty

Well in answer to my own question they are M8x20

But some bolts screw up the speedo reading, so using Titanium is a bad move (so I found out after some research) not sure about Stainless

I think they may need to be magnetic so I guess stainless are out as well but I am no metallurgist tbh!!

Agree with above , yer speedo works off them so have to be magnetic. Contact Aprilia Perfomance they will guide you with everything :thumbup

Yeah seems some screw up the speedo

I ended up getting these below which are just Zinc plated over steel?

Worst case is they wont work, and I will just clean up the original Ones, and put them back on lol
