Description
Athena Sport Pro 80 Alu Cylinder
Complete cylinder kit (incl. piston and cylinder head) Sport Pro 80cc long stroke by Athena.
Performance Athena 80cc ALU Sport cylinder
Nikasil-plated aluminium, 5 transfer ports, single exhaust port, single-ring piston (12mm pin) and high-compression cylinder head. It is similar to the Sport Pro series cylinders, but can be installed with a longer stroke (43mm, 44mm for Piaggio engines) crankshaft (85mm rod) increasing displacement to 80cc.
This is designed for low/mid range torque resulting in good acceleration. We recommend a 21mm carburetor minimum as well as a racing exhaust (such as Yasuni C16, Roost, R1400 etc...). With the appropriate components and adjustments, you can expect 17 to 19hp (15hp on vertical Minarelli AC engines).
Note: this kit requires advanced tuning!

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.
