FS570, front caliper offset ??

nico570 · Jul 2, 2015

Hi there,
I am willing to replace the OEM magura radial caliper of my FS570 with a brembo (..I already got a 15 rcs mc).
I was wondering if the brembo caliper P4 30/34 100 mm motard radial (XA78910) would fit my OEM front wheel and braking rotor, plug and play?.
I read offset of the brembo caliper is 30mm, is it the same as the OEM magura caliper?
Is it a big improvement over the magura?
and what difference compared with other 'standard' brembo monobloc, plenty of on ebay (never had a cnc before) ? worth the price?
different offset as well? any difference in size (distance from spokes?)
Thx for feedback,
Nico

OK..

..i'll reply to myself, i measured it eventually, it's 30mm offset for both ccalipers, brembo sm XA78910 and OEM magura.

I still have a question, the brembo billet is billet, but also 2 pieces,
while all the brembo radial cast on ebay (like the ones I had on the beemer, or the 1199) are monobloc.

How would a billet 2pieces be better than a cast monobloc? and what justifies the price of this caliper??

That caliper is very narrow.
Therefore fits supermoto and not collide with the spokes.

Monoblock calipers from sport bikes are very very wide. Their installation is impossible without wide triple clamps and caliper machining.

I have standard ktm caliper P4 34/34 from 690. Wide Suter triple clamps.
And I had to machining back of caliper to mount it because I have 310mm rotor.

The question still is: what brake disc you have and what front wheel.

310mm + 17" = tight.
310mm + 16,5" = ok
320mm + 17" = ok
320mm + 16,5" = ok, but the problem with removing the caliper

Thx that's very interesting, the four indications you give ( tight, ok etc..) are for the brembo XA78910 ?

My front disc is 310MM, on a 17 wheel,
so safe upgrade is Brembo SM caliper + 320 rotor in case I want to keep 17"
what does the wheel diameter change? The inclination of spokes?
