Long-established Spanish company Airsal manufactures very high-quality cylinder kits in its own factory. With decades of experience in cylinder manufacturing, Airsal offers tuning kits that deliver a substantial performance increase while ensuring the longest possible service life. This is achieved not only through features such as the aluminium construction with an extra-hard-coated cylinder bore surface. The other components, such as pistons and piston rings, are also consistently of the highest quality. Airsal can also supply individual spare parts for every kit, including gasket sets, piston rings, piston pins and more.

We offer high-quality aluminium sport cylinders from Airsal, providing significantly better heat dissipation than cast iron cylinders. Their hard-coated cylinder bore surface is also extremely tough, ensuring a long service life!

In terms of performance, the 50cc Sport is on a par with Polini or Malossi Sport, while the 70cc Alu Sport cylinders deliver slightly better performance than the DR Evo, for example. A larger carburettor is not strictly necessary, but the main jet should be adjusted.

This 70cc Airsal aluminium Sport cylinder delivers excellent acceleration at lower overall engine speeds. One of the most practical Sport cylinders for everyday use, at a great price. The cylinder is also suitable for use with stock exhaust systems. The main jet must be adjusted, or better still, upgrade straight to a 17,5mm carburettor.
