As gc6269 said, they bolt straight on. As far as Icould find out, no one seems to make an aftermarket 330mm disc for the Multi. You could use the 320mm and take the caliper spacers out but I just decided to spring for the serie oro based on a recommendation from this forum, thru Motocarpi. Cheapest deal I could find.

My 1260S had sqeaking front brake from new, did it at slow speeds coming to a stop. Changed pads to Brembo SC and problem has gone, much better pads too, brakes are excellent.
Unfortunately, the duty I’d have to pay on those prices them out of reach, but that’s handy for anyone in the US that want them.
