The 860cc conversion kit for all BMW R65 models from 9/80 onwards, including all Head Gaskets and Installation Instructions.

The kit contains Nikasil coated cylinders with lighter (150g), spontaneous quiet running pistons. The kit also contains new piston rings, piston pins and stainless steel push rod tubes already installed in the cylinders. The piston shape is specially designed to require no further modifications to the head. All gaskets are included for installation!

The conversion increases horsepower by 20% and a maximum torque of 75Nm at 4200rpm.

NOTE: The compression pressure will be over 10Bar - similar to the stock compression pressure.
