The standard dimension is 67.00 mm .
The cylinder internal dimension is measured. 1. Compression ring: rectangular ring - DLC-coated due to the Nikasil-coated cylinder track 2. Compression ring: minute ring for quick running-in or adjustment of the ring (with or without anti -rotation device) Oil scraper ring : 3-part - 2 steel rings with hard-chromed running surface - 1 clamping ring
IMPORTANT:
Since the BMW K75/K100 models have undergone a change in the engine (cylinder head, pistons and piston rings) over the years, you have to be careful here! Therefore there are different spare part numbers.
You should not simply go by the year of manufacture of your K, as theoretically a previous rebuild could have used pistons from a different year. In order to be sure which ring set you need, you must check whether your pistons have an anti-twist device on the 2nd compression ring (minute ring) or not.
