Hot 
Cylinder cover suitable for Cilo Cross, Pony Cross and GTX mopeds / mopeds with Beta 521 or 512 engine.
The highly compressed cylinder head impresses with its high-quality workmanship and precise fit. Due to the 1.1 mm reduced crushing edge compared to the original head, this is now 2.5 mm instead of 3.6 mm (measured with the original 1 mm thick gasket). A lower crushing edge ensures better combustion due to increased turbulence in the combustion chamber, which significantly increases performance and efficiency.
If you want to reduce the pinch edge even further, you can find the 0.3 and 0.5 mm thick gasket in the accessories section.
Good, inexpensive standard spare part. GPO – GOOD PARTS ONLY.
