43.5 mm cylinder cover suitable for your Cilo Cross, Pony Cross and GTX moped / moped with Beta 521 or 512 engine and corresponding Airsal 43.5 mm racing kit.
The tuning cylinder head impresses with its high-quality workmanship and precise fit. With the 0.5 mm thick head gasket from Airsal, the crushing edge is only 1.2 mm. Compared to using the racing cylinder with an original head, not only is the combustion chamber geometry optimized by the matching diameter, but combustion is also improved by the lower crushing edge. This leads to greater turbulence in the combustion chamber, which increases performance and efficiency.
If you want to reduce the pinch edge even further, you can also find a 0.3 thick gasket among the accessories.
You can find cylinder head gaskets, the matching racing cylinder and a carburetor set in the accessories section.
Good, inexpensive standard spare part. GPO – GOOD PARTS ONLY.
