Description
Airsal 72cc Aluminium Cylinder Kit "Sport" Derbi Euro 3 (D50B0).
This Sports version of the Airsal cylinder is made of Nikasil-coated aluminium for improved cooling. The exhaust port is divided for improved flow, the 48mm piston is a 1-ring piston.
To get the most out of it, we recommend setting it up with a bigger carburetor (at least) like this 19mm carburettor and a sports exhaust (such as this one by Stage6).
Bore: 48mm / 72.4cc = not street-legal.
Note: Models with Derbi Euro 4 engine use a slightly smaller temperature sensor (thread: M12 x 1.5) than the Euro 3 models (M14 x 1.5). To fit the smaller Euro 4 sensor on the cylinder head, you will need the adapter MF96.91010.
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: Sport
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.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
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.
