Description
Cylinder Athena 70cc, Sachs-Hercules.
Athena is a company that specializes in standard and racing parts for motorcycles and scooters.
If your original cylinder gives up the ghost, you have to decide whether you want to replace it with an OEM quality replacement (without any real increase in performance) or go in the direction of performance improvement. With the right cylinder, you can get a tremendous amount of performance, whether it's through port timing, displacement, or other features.
Aluminum is used for high quality cylinders. The raceway is coated with an extremely hard and resistant coating. The advantages of an aluminum cylinder are better heat dissipation and low weight, plus the tolerances of the piston clearance are kept low by the material, resulting in more power. If the piston rubs (slightly), in many cases it is not necessary to replace the entire cylinder but only the piston, because the coating is very resistant.

How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.
Tuning Level: Racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
