Cylinder kit Athena Sport Pro 80CCM Minarelli LC
Athena Sport Pro 80cc cylinder for long-stroke crankshafts (43mm) - powerful long-stroke tuning cylinder for liquid-cooled Minarelli engines (Yamaha Aerox, MBK Nitro).
Performance Athena 80cc ALU Sport cylinder
The Athena Sport Pro 80ccm is one of the few long-stroke cylinders not built for extreme revs. It's identical in design to the Stage6 Sport Pro MK1 but with 4mm longer stroke. This is an aluminum cylinder with Nikasil coating, 5 transfer ports, and a simple exhaust port. It comes with a 1-ring piston (12mm piston pin) and a high-compression one-piece cylinder head, made for crankshafts with 43mm stroke and 85mm conrod. Displacement is increased to 80cc.
Thanks to the longer stroke, the bore/stroke ratio is improved, giving the engine a much better power curve than tuning cylinders designed for standard stroke. The result is solid torque – in other words, "more power" across the full RPM range, boosting both acceleration and mid-range punch. For even more performance, we recommend a 24mm carb and a racing exhaust (e.g. Yasuni C16, Stage6 R1200, etc.). With the right setup and tuning (carb, variator, etc.), this kit can easily reach 17–19 hp – awesome! But heads up – a bit of know-how and experience is definitely recommended.

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.
