Oil control ring, made by Schoettle, threepart (so called Niflex ring)
best German quality, less wear in cylinder
bore: 79.0 mm, height: 5.0 mm
for all models
Attention: Because theses rings scrape the oil very effectively, you should always mount only one oil control ring! That means the downward notch remains empty. Otherway the piston could run too dry.
