Description
Bidalot cylinder 80cc (47.6/44.9) Factory 2011 AM6
Bidalot is a French tuning company for high-end racing products with which over 100 championship titles have already been won.
Some manufacturers also sell cylinders "naked", i.e. without cylinder head and piston. Simply keep the original cylinder head and use it with the new cylinder.
Aluminum is used for high-quality cylinders. The bore is given an extremely hard and resistant coating. The advantages of an aluminum cylinder are better heat dissipation and low weight. In addition, the tolerances of the piston play are kept low by the material, which leads to more power. If the piston starts to rub (slightly), in many cases it is not necessary to replace the entire cylinder but only the piston, as the coating is very resistant.

Of course, you need a bit of know-how to install the racing parts correctly and adjust them to yield maximum power.
To get the full potential out of your engine, we recommend buying a high-quality carburetor with the right diameter for the selected displacement.
Also remember to adapt the chassis to the increased engine power, e.g. with improved brakes and suspension.

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.
