Cylinder Kit Top Performances TPR 80cc aluminium d=50mm AM6
Description
Top Performances TPR80 aluminum AM6 cylinder kit
For the upper MidRace segment, Top Performances developed the TPR 80 aluminium cylinder kit for AM6 engines. With a 50mm bore, it reaches an actual displacement of 76.5cc — the maximum possible without switching to a long-stroke crankshaft.
A bridged exhaust port and modular cylinder head are standard on this kind of high-performance setup. The modular head is directly water-cooled, offering far better thermal performance than traditional one-piece heads. Depending on your setup, the TPR delivers around 20 hp.

To get the most out of this cylinder, you should run it with a 21-28mm carburetor and an appropriate racing exhaust.
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: High End 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.
High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.
Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.
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.
