It doesn't always have to be a new Cylinder..

Once a Cylinder has covered a few thousand kilometers, it is essential to replace the Piston Rings or even the Piston in order to continue to ensure reasonable compression. We have the most important spare and wear parts for all common tuning and original cylinders in stock for you: i.e. Pistons, Piston Rings, Piston Pins, Gudgeon Pin Retaining Rings and Gasket Sets.

The main function of Piston Rings is to seal the combustion chamber from the crankcase and to transfer heat from the piston to the Cylinder. In addition, they play an important role in regulating the lubricating oil balance.

Piston Rings are subjected to high stresses and are therefore prone to wear. Loss of compression, decreased performance, or poor starting can be signs of worn Piston Rings.

We offer Piston Rings up to the 4th oversize (OS) for many models and cylinders. The specified bore or diameter (Ø) always refers to the Cylinder’s dimensions. Depending on the application, different designs are used: standard and L-shaped Piston Rings, as well as trapezoidal or semi-trapezoidal versions for tuned cylinders.
