Don´t mean to start a discussion whether you NEED floating rotors, I was just looking to see what is out there for the R nineT. (Was looking at cars actually but got carried away)

The R nineT shares the OEM rotor with
  • K52 (R 1200 RT)   (01/2013 — )
  • K53 (R 1200 R)   (11/2013 — )
  • K54 (R 1200 RS)   (06/2014 — )
  • K21 (R nineT)   (01/2013 — )
  • K73 (F 800 R)   (11/2013 — )
  • K49 (S 1000 XR)   (05/2014 — )

According to OPP Racing the Brembo 208973751 fits the R nineT, it is Brembos Supersport discs. Same braking surface width of 34mm, slightly thicker at 5.5mm compared to OEM 4.5mm, no adjustments necessary.

Fits the following bikes
BMW R Nine T 2014-2015
BMW S1000R 2014-2015
BMW S1000RR 2009-2015

Also this UK company lists them as compatible with the HP2.

But, if the fitment is the same as the BMW S1000R 2014-2015 and BMW S1000RR 2009-2015 listed by OPP racing, there are more possibilities.

From some Thailand outfit without a webpage, but those rotors are from Alpha Racing, mated with Brembo M4 monoblock calipers.

It´s worth to note that due to increased thickness, Alpha racings rotors come in at 1.56 kg compared to OEM rotor weight of 1.15kg.

My best guess is that it would be marginal upgrade at best. Mostly it´s a bling upgrade. Only heavy use on track would you really benefit. That said, even Nate Kern on his track prepared R nineT didn´t upgrade his brakes.

Wouldn´t necessarily stop me from doing it though ;)
