Piston Airsal d.39,90mm, Derbi D50B0.

Airsal is a Spanish brand known for top cylinders at unbeatable value for money.

The piston with piston ring(s), piston pin and circlips is the moving heart of the cylinder. Due to the constant up and down movement, the piston is subject to wear. At some point the tolerances are no longer correct, the piston ring no longer seals perfectly and the performance decreases, i.e. the piston must be replaced.

Technical details:

  • Bore: 40 mm
  • Piston pin: 12 mm
Questions about the product
Notes and Safety

When to replace the piston?

To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).

Extending Piston life

To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.

It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.
