Can you confirm that the 765LT standard (non-senna upgrade) front brake rotor is the same size as the 720s/750s.
I'd like to put the standard 765LT front calipers onto the 750s but just need to confirm the rotor size are the same between both models. The 750s runs the same break booster as the 765LT so is should work?

 

Yes, if the caliper is CP7728:

So the 765LT only uses the Senna caliper, regardless of whether it has the Senna rotors?

 

The 765LT utilises the same Rotors as a 720s/600 LT and presumably the 750s, although I can’t confirm that

The front Calipers are Senna’s and the rears 720s, however the front pads while being same shape as Senna pads are of a different compound

Senna Rotors are a different compound and were an option on a 765LT

This just adds to the confusion. You say that the 765 has the same rotors as the 720/600, but then you go on to say the front rotors are Senna and the rears are 720?

My understanding, previously, was that the 765, 720 and 600 all share the same front brake components unless the 765 was specified with the Senna upgrade, in which case it would have the long fiber rotors and monobloc caliper.

 

I am just at my dealer right now for my 650s annual service and I got the chance to find a 765lt in the show room without the Senna brakes. So it seems that the 765lt always get the big calipers but you have either the CCM rotors or the CCB if track brake option

 

Now I want that caliper!
