Hi all. Soon to change the front discs on my MTS1200, probably getting Serie Oro. Anyway I’m thinking the original bolts are 9 years old, so probably an idea to get new ones, some might get damaged coming off. Any recommendations on decent suppliers of replacement bolt kits? TIA
For safety critical items such as brake disc or calliper bolts, on a bike used mainly on the road, I'd stick with OEM. At least someone has done some stress calcs and made sure the material is suitable. Probably unlikely to be supplied with bogus bolts from an authorised Ducati dealer. In some cases you can't be sure what material, and hence suitability (tensile and shear strength etc) is for bolts bought off the interweb.
Agree with MrB and they are not expensive. IME, preparation for removal is the key. Make sure the Torx holes are clear of any debris so the Torx bit will bottom out. Apply heat to the bolt head, hot air gun, soldering iron, anything to heat the dried thread lock to help it release. Make sure the wheel is supported absolutely flat so it won't move about when you put the Torx bit in. Use a long fixed wrench, not your ratchet and apply pressure slowly. Release each bolt before undoing and removing any of them. Please, please, please, don't consider using a rattle gun. Andy
Thanks for the info, especially the rattle gun!! I shall be standing over the guys in the workshop. So far they have been very careful and torque everything to spec.

OEM or full test certificates. All fastening must be traceable in safety applications and fit for use in cosmetic applications. Can't trace no buy. Lot of stainless crap in the market which only conforms to dimensional specs and if you are lucky chemistry, great for industrial kitchens. Titanium has become the new market for the CNC shiny crap brigade buying bar stock from the Chinese. They print impressive certification.
Just done it on my 899, You need lots and lots of heat Michel, how to with pics here - https://www.ducatiforum.co.uk/threads/can’t-get-disc-bolts-out….86637/ key to getting them out easily is lots of heat on the bolt and letting it soak for a while to melt the Loctite,..it’s a bugger !
As Mr Bumble says, OEM Ductile for safety critical parts. Probably cold rolled too rather than machined threads. dams site easier to drill out too should shit happen.
Most people say the Ducati bolts are made of cheese. Quite a few people swap them out for Ti or Stainless. Obviously they need to be a suitable grade though.
mine seem to de good for 10 years old, new ones ordered about £1 per bolt. Usual super service from Craig at Moto Rapido.
