On my GRiSO 1200 8V 2010, one or both discs are wobbling. The bike has around 12.500km on the clock. Does anyone know of a pair of used non wobbling brake discs available?

Or a referance to a supplier of new discs with reasonable prices?

The article number is : 977835

Shipment to Norway is needed.

Had extactly the same problem with mine.
I can recommend "Probrake".



According to probrake the PB001 rotors/disks are produced by Braking in Italy.

Don't forget to change your change the bolts - I would only recommend the genuine bolts.
Torque setting is very important for these bolts.
Discs transmit stopping power to the wheel by the clamping force between the surface of the disc and mounting face on the hub. This force is provided by the bolts - the bolts should not be in shear - only tensile loading.
Budget stainless (or any stainless) via online suppliers are not the way to go.
The factory supplied bolts are of the correct grade for the application - they are very crafty and don't include the grade on the head of the bolt.
The correct torque value takes the bolt beyond the elastic limit and close to the UTS for material - hence the requirement for changing the bolts every time they are removed.

On the balance of probability, reusing the old bolts, using the wrong spec will probably work fine but why take a chance on the most important part of your bike.

Are the discs out of true OR are the bobbins clogged ?.....surprised you need new discs at 12,000 km as mine last at least 30K miles plus...

I have rotated the bobbins - so I do not know what is wrong.

I bought the Brembo discs for the SE-models today. Let me see what happens when I replace the old original with these new Brembos.

Will let you all know.

New to the for discs or new - recently replaced.
If your pads were the cause for the early failure of your current discs then it could pay to fit an alternative type.

Old original disc + original pads = wobbling

Bought new pads because I hoped that could help = negative

That is why I today have bought new discs. The new pads have only a few km.

Or you could substitute the titanium for plastic licence plate screws or perhaps screws made from cheese.

Edam or Gruyere.....although apparently with cheese bolts you need to change torque settings, use anti-sieze & watch out for galling & unexpected breakage
