Fitting Brembo calipers on 05'R1

Hi All,

1st post on the forum and would like to start by making a question:

I have the chance to get a set of Brembo calipers from a guy that is parting out an 04' Aprilia RSV mille.
-Does anyone knows if they will fit an 05'R1?
-They're 100mm spaced bolt-to-bolt, I just don't know how wide the caliper mounting hole is. (from the caliper to the fork)

Thanks in advance :bow

The stock calipers are made by Brembo, I do believe. Unless you are a very competent rider/racer, I don't see much reason to "upgrade" to the ones in reference, except for looks. Just my 2 cents on the matter.

Ya, but if someone were to just give the calipers to me...as in this case...he'll I'd put them on.

They will not fit. The mounting dimensions on the Brembo OEM radial calipers as fitted to the RSVR Factory and Ducati 999 have totally different mounting dimensions. They are 100mm center to center, and have a different offset from disc centerline to the mounting holes as well.

The calipers on the '04-05 R1's are made by Sumitomo.

The bolt spacing and offset from centerline on these and the Tokico's as equipped on the other japanese bikes are the same as those for the Brembo racing radial mount calipers (108mm bolt spacing, 22.5mm from disc centerline to hole centerline).

So a set of Tokiko's like the ones below from a gsxr would fit?
(It's just a looks thing, I really don't like the stock calipers on the R1)

stock brake calipers are by sumitomo.front and rear master cylinders are by brembo.

Yes, the Tokico's would fit, simply by using some small cylindrical spacers to get the caliper height correct.

But the OE Sumitomos are better. Also, the Sumitomos have smaller pistons, so if you were to switch to Tokicos (or Brembo racing calipers, for that matter), a master cylinder change would be recommended as well, to a bigger bore size, otherwise you will have way too much lever travel.

Thanks for helping me out. I will keep the OEM equipment for now and maybe do a complete swap for Brembo's later on.

Personally I would not change the R1 calipers unless they were for a billet Monoblock caliper. The OEM sumitomo calipers are monoblock and work very well. The weak link is the master cylinder as it is a bit on the small side at 14mm bore so it could be changed for a 17.5mm bore or an ajustable ratio master like the ISR one martinc has. If you need to change the caliper then you can go for the hugely expensive Brembo monoblock or again the ISR six piston radial monoblocks.
