    Replacement 1000 cc piston.


    Siebenrock 1000cc pistons 9.5:1.

    Fits all 1000cc Nikasil cylinders, including the original BMW cylinders.

    At 9.5:1 compression, this kit is an excellent way to restore torque and HP to the low compression engines from 1981-on with parts that have less reciprocating mass for a smoother and more responsive engine.

    To lower compression to 8.8:1 use one part number 11 11 1 335 650 base gasket under each cylinder.

    Sold individually, for a set order quantity of two.

    Kit Includes:

  • Moly coated lightweight 9.5:1 forged pistons.
  • Lightweight high performance wrist pins.
  • Set of 4 pin clips.
  • Complete ring set compatible with Nikasil cylinders.

    Specify your cylinder type A, B or C below which is stamped at the base of your cylinder.
