The PRS2PK radial brake master cylinder comes with a integrated fluid reservoir, perfect for "Naked" or Streetfighter style machines where a seperate fluid reservoir looks wrong or does not suit.
PRS2PK has a 19mm piston ideal for most modern twin disc braking systems and is adjustable through 17/18/19 ratios so can be fine tuned to suit any riding conditions from a dry, hot race track to a damp, cold road.
Featuring the same patented twin cam adjustment system as the standard PRS2 cylinder that enables lightning fast ratio changes while retaining plunger/piston alignment, PRS2PK is Italian engineering at it's best!
