Description
cylinder Airsal Sport 70cc Derbi Euro 3 / 4 (D50B0)
Cylinder kit Airsal Alu Sport 70cc, aluminum cylinder suitable for everyday use from the Spanish manufacturer Airsal, sport version.
The cylinder has a 48mm bore and therefore a genuine 73cc. Due to its comparatively low port timings, it offers a smooth torque curve and a relatively wide usable rev range. The cylinder can be used with an original exhaust, but a sports exhaust is highly recommended, as is a 19mm carburetor.
Bore: 48mm / 73cc = not street legal.
Details Airsal Sport Derbi Euro 3 / Euro 4
- Aluminum cylinder with 5 transfer ports and split exhaust
- 1-ring piston, 48mm
- Aluminum cylinder head
- Gasket set included
Note: 50cc bikes with Derbi Euro 4 engines 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 to the cylinder head, you also need the MF96.91010 adapter.

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.
